That&#8217;s the direct answer. The rest of this guide is about why that distinction matters more than most spec sheets let on.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">If you&#8217;ve spent any time scrolling Amazon listings or supplier catalogs lately, you&#8217;ve probably noticed &#8220;Bluetooth 5.4&#8221; popping up on more spec sheets. Some listings pair it with claims like &#8220;2x faster transmission&#8221; or &#8220;30% lower power consumption.&#8221; Other listings barely mention it at all. That inconsistency is the problem I run into constantly when buyers ask me to explain what they&#8217;re actually paying for.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">I work on the factory side of <a href=\"https:\/\/www.tashells.com\/what-are-tws-earbuds\/\">TWS earbuds<\/a> production, so I see the chipset datasheets before the marketing copy gets written. Most of what gets advertised about Bluetooth 5.4 in earbuds listings is inflated &#8211; the version number tells you about connection management and security, not about how the earbuds will sound.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">This guide breaks down what Bluetooth 5.4 actually changes, what it doesn&#8217;t touch, and how to decide whether it&#8217;s worth requesting on your next production run.<\/span><\/p><h2 class=\"md-end-block md-heading\"><span class=\"md-plain\">The Full Definition<\/span><\/h2><p class=\"md-end-block md-p\"><span class=\"md-plain\">To put a bit more precision on the one-line answer above: Bluetooth 5.4 was ratified by the Bluetooth Special Interest Group (SIG) in February 2023 as an extension of the Bluetooth Low Energy (LE) standard. It governs how devices advertise themselves, establish connections, and protect that connection data once paired. Nothing in the spec touches audio compression or codec support &#8211; that layer is defined separately, by the chipset and firmware.<\/span><\/p><h2 class=\"md-end-block md-heading\"><span class=\"md-plain\">Where <a href=\"https:\/\/www.tashells.com\/product\/ts-k4-tws-wireless-earbuds-with-case-bluetooth-5-4-oem-manufacturer-wholesale-best-earphones\/\">Bluetooth 5.4<\/a> Fits in the Bluetooth Timeline<\/span><\/h2><p class=\"md-end-block md-p\"><span class=\"md-plain\">For context, here&#8217;s how the recent versions build on each other in TWS earbuds:<\/span><\/p><figure class=\"md-table-fig table-figure\"><table class=\"md-table\"><thead><tr class=\"md-end-block\"><th><span class=\"td-span\"><span class=\"md-plain\">Version<\/span><\/span><\/th><th><span class=\"td-span\"><span class=\"md-plain\">Released<\/span><\/span><\/th><th><span class=\"td-span\"><span class=\"md-plain\">What it added for earbuds<\/span><\/span><\/th><\/tr><\/thead><tbody><tr class=\"md-end-block\"><td><span class=\"td-span\"><span class=\"md-plain\">5.0<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">2016<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">Longer range, faster data rates &#8211; made practical true wireless design possible<\/span><\/span><\/td><\/tr><tr class=\"md-end-block\"><td><span class=\"td-span\"><span class=\"md-plain\">5.1<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">2019<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">Direction finding (used for &#8220;Find My Earbuds&#8221; style features)<\/span><\/span><\/td><\/tr><tr class=\"md-end-block\"><td><span class=\"td-span\"><span class=\"md-plain\">5.2<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">2020<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">LE Audio and the LC3 codec, laying the groundwork for lower-bitrate, better-quality streaming<\/span><\/span><\/td><\/tr><tr class=\"md-end-block\"><td><span class=\"td-span\"><span class=\"md-plain\">5.3<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">2021<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">Connection Subrating, for more efficient power handling during active connections<\/span><\/span><\/td><\/tr><tr class=\"md-end-block\"><td><span class=\"td-span\"><span class=\"md-plain\">5.4<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">2023<\/span><\/span><\/td><td><span class=\"td-span\"><span class=\"md-plain\">Periodic Advertising with Responses (PAwR), encrypted advertising data, refined LE security<\/span><\/span><\/td><\/tr><\/tbody><\/table><\/figure><p class=\"md-end-block md-p md-focus\"><span class=\"md-plain md-expand\">Each version is additive.

This is the part most buyer-facing content skips.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Periodic Advertising with Responses (PAwR)<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">This is the headline feature. Before 5.4, a device broadcasting periodic advertisements (like a beacon) could only send data one way &#8211; it couldn&#8217;t get a response back without setting up a full connection. PAwR lets a central device send periodic broadcasts to multiple peripherals, and those peripherals can respond without a full connection handshake.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">This is the mechanism behind Auracast-style broadcast audio, where one source can serve multiple listeners at once &#8211; think gym equipment broadcasting audio to many headsets, or public venues offering multi-language audio feeds. For most consumer <strong><a href=\"https:\/\/www.tashells.com\/product-category\/tws-earbuds\/\">TWS earbuds<\/a><\/strong> today, PAwR is present in the chipset but not yet activated as a customer-facing feature, since it depends on the LE Audio ecosystem maturing on the phone side too.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Encrypted Advertising Data<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">Before 5.4, the advertising packets a Bluetooth device broadcasts while searching for a connection were sent in plain text. That meant device identifiers and some connection metadata were technically visible to anything scanning nearby. Bluetooth 5.4 adds encryption to this advertising data, so that information isn&#8217;t exposed during the broadcast phase.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">For earbuds specifically, this is a modest but real privacy improvement &#8211; it closes a small gap in how much a nearby scanner could infer about your device before a connection is even made.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Refined LE GATT Security<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">Bluetooth 5.4 also updates the security model around GATT (Generic Attribute Profile), the mechanism devices use to exchange data after they&#8217;re connected. The changes tighten how permissions and authentication are handled at the protocol level. It&#8217;s a background improvement &#8211; not something a user notices, but relevant for anyone building connected accessories with data exchange beyond basic audio.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-plain\">For the full technical spec, the <\/span><span class=\"md-meta-i-c md-link\"><a href=\"https:\/\/www.bluetooth.com\/specifications\/specs\/\"><span class=\"md-plain\">Bluetooth SIG&#8217;s official Core Specification page<\/span><\/a><\/span><span class=\"md-plain\"> lists everything ratified in version 5.4 and every version before it.<\/span><\/p><h2 class=\"md-end-block md-heading\"><span class=\"md-plain\">What Bluetooth 5.4 Does NOT Change<\/span><\/h2><p class=\"md-end-block md-p\"><span class=\"md-pair-s \"><strong><span class=\"md-plain\">It does not change the audio codec.<\/span><\/strong><\/span><span class=\"md-plain\"> SBC, AAC, aptX, LDAC, and LC3 support are determined by the chipset and firmware, not by the Bluetooth version number. A Bluetooth 5.3 earbud with LDAC support can sound better than a Bluetooth 5.4 earbud that only supports SBC. If a listing claims &#8220;5.4 means better sound,&#8221; ask what codec is actually implemented.<\/span><\/p><p class=\"md-end-block md-p\"><span class=\"md-pair-s \"><strong><span class=\"md-plain\">It does not guarantee faster or more stable audio streaming.<\/span><\/strong><\/span><span class=\"md-plain\"> Aggressive throughput or battery-savings figures on some marketplace listings are typically chipset-vendor marketing applied loosely to the Bluetooth version, not numbers defined by the Bluetooth SIG itself. The real-world gains from 5.4 are in connection management and security, not raw audio throughput.<\/span><\/p><p class=\"md-end-block md-p md-focus\"><span class=\"md-pair-s \"><strong><span class=\"md-plain\">It is fully backward compatible.<\/span><\/strong><\/span><span class=\"md-plain md-expand\"> A Bluetooth 5.4 earbud will pair fine with a phone running Bluetooth 5.0 or even earlier LE-capable versions. The devices negotiate down to whatever features both sides support. So if a customer&#8217;s phone doesn&#8217;t support 5.4, they still get a working pair of earbuds &#8211; they just won&#8217;t access the 5.4-specific features like PAwR.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5c77ff2 e-flex e-con-boxed e-con e-parent\" data-id=\"5c77ff2\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\" data-core-v316-plus=\"true\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2dc8141 elementor-widget elementor-widget-text-editor\" data-id=\"2dc8141\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h2 class=\"md-end-block md-heading md-focus\"><span class=\"md-plain md-expand\">Does Bluetooth 5.4 Matter for Your Product Right Now?<\/span><\/h2><p class=\"md-end-block md-p\"><span class=\"md-plain\">This depends on who you&#8217;re building for.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">For Amazon Sellers and Brand Owners<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">If you&#8217;re testing a new SKU, Bluetooth 5.4 is a reasonable checkbox to have on the spec sheet for future-proofing, since chipset cost difference versus 5.3 is usually marginal at the volumes most Amazon sellers order. But don&#8217;t let it replace the specs that actually affect the customer&#8217;s experience: codec support, driver quality, ANC\/ENC tuning, and battery life. A listing that leads with &#8220;Bluetooth 5.4&#8221; but is vague on codec support is usually compensating for a weaker spec sheet elsewhere.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">For Wholesale Buyers and Distributors<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">If you&#8217;re moving inventory at scale, Bluetooth version is rarely the deciding factor for reorders &#8211; price stability, defect rate, and consistent supply matter more. Bluetooth 5.4 is worth noting on your product data sheet for retail-facing markets (especially EU and UK buyers who increasingly ask about it), but it shouldn&#8217;t drive your supplier selection on its own.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">For Brand Owners Doing Full Custom Development<\/span><\/h3><p class=\"md-end-block md-p md-focus\"><span class=\"md-plain md-expand\">If you&#8217;re doing a custom ID with a longer product lifecycle, it&#8217;s worth specifying Bluetooth 5.4 chipsets now so the product doesn&#8217;t look dated at launch 12-18 months out. This is really a chipset platform decision made early in the <a href=\"https:\/\/www.tashells.com\/oem-odm-service\/\">ODM\/OEM<\/a> process, not something you bolt on later.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-b9c81b8 e-flex e-con-boxed e-con e-parent\" data-id=\"b9c81b8\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\" data-core-v316-plus=\"true\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-58aa79d elementor-widget elementor-widget-image\" data-id=\"58aa79d\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1000\" height=\"562\" src=\"https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review.webp\" class=\"attachment-full size-full wp-image-5452\" alt=\"Reviewing a TWS earbuds Bluetooth chipset spec sheet\" srcset=\"https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review.webp 1000w, https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review-300x169.webp 300w, https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review-768x432.webp 768w, https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review-18x10.webp 18w, https:\/\/www.tashells.com\/wp-content\/uploads\/2026\/08\/amazon-seller-earbuds-spec-sheet-review-600x337.webp 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c697278 e-flex e-con-boxed e-con e-parent\" data-id=\"c697278\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\" data-core-v316-plus=\"true\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-96c96fb elementor-widget elementor-widget-text-editor\" data-id=\"96c96fb\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><strong>Bluetooth 5.4 and Chipset Platform Adoption<\/strong><\/p><p>Bluetooth version support lives at the chipset level, so it&#8217;s worth knowing where the major TWS platforms stand:<\/p><p>&#8211; <strong>Qualcomm QCC series<\/strong>\u00a0&#8211; support is available across current-generation QCC platforms, typically paired with aptX codec options.<br \/>&#8211; <strong>Airoha<\/strong>\u00a0&#8211; widely used in mid-range and value TWS designs; 5.4-capable variants are in production and commonly paired with LC3 and standard SBC\/AAC support.<br \/>&#8211; <strong>BES (Bestechnic)<\/strong>\u00a0&#8211; a common choice for cost-sensitive OEM\/ODM builds; capable SoCs are available, though many high-volume orders still run on mature 5.3 platforms for cost reasons.<br \/>&#8211; <strong>Jieli <\/strong>&#8211; popular for entry-level and budget TWS; adoption here is newer and less standardized across product lines, so it&#8217;s worth confirming per-model rather than assuming platform-wide support.<\/p><p>By late 2023, Qualcomm, MediaTek, and Broadcom chipsets had begun supporting the spec, and by 2026 it&#8217;s become common in mid-range and higher-end wireless earbuds, though budget tiers still lean on 5.3 for cost reasons.<\/p><p><strong>How to Decide: Spec Bluetooth 5.4 or Stick with 5.3<\/strong><\/p><p>If you want a deeper side-by-side on the two versions specifically for TWS production, we&#8217;ve also broken that down in [<a href=\"https:\/\/www.tashells.com\/bluetooth-5-3-vs-5-4-earbuds-whats-the-difference\/\">Bluetooth 5.3 vs 5.4 Earbuds: What&#8217;s the Difference<\/a>].

When a customer asks about Bluetooth 5.4, we walk through which platform (QCC, Airoha, BES, or Jieli) fits their price point and codec needs, confirm certification status (FCC, CE, RoHS, BQB), and quote both 5.3 and 5.4 chipset options side by side so the customer can see the real cost delta before deciding. For most new SKU development at Tashells Audio, we can run either version on the same tooling, so it&#8217;s a configuration decision rather than a full custom build.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8ed03c1 e-flex e-con-boxed e-con e-parent\" data-id=\"8ed03c1\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\" data-core-v316-plus=\"true\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-8bdfd8a elementor-widget elementor-widget-text-editor\" data-id=\"8bdfd8a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h2 class=\"md-end-block md-heading md-focus\"><span class=\"md-plain md-expand\">FAQ<\/span><\/h2><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Is Bluetooth 5.4 better than 5.3 for <a href=\"https:\/\/www.tashells.com\/product-category\/products\/\">earbuds<\/a>?<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">For most listening use cases, the practical difference is small.

Sound quality is governed by the audio codec (SBC, AAC, aptX, LDAC, LC3) and the driver\/DAC hardware, not by the Bluetooth version number. Bluetooth 5.4 can carry the same codecs as 5.3 &#8211; it doesn&#8217;t add a new audio codec on its own.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">What earbuds have Bluetooth 5.4?<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">Adoption has grown steadily since chipsets from major platforms began supporting the spec in late 2023. By 2026, Bluetooth 5.4 shows up across a growing share of mid-range and premium TWS earbuds, though many budget models still ship on Bluetooth 5.3 chipsets.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Is Bluetooth 5.4 backward compatible with older phones?<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">Yes. Bluetooth 5.4 earbuds will pair with phones running Bluetooth 5.0, 5.1, 5.2, or 5.3, since Bluetooth versions extend rather than replace earlier specs. The connection simply uses whichever features both devices support in common &#8211; so a 5.4 earbud paired to a 5.0 phone still works, just without the 5.4-specific features active.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">Do I need Bluetooth 5.4 earbuds specifically?<\/span><\/h3><p class=\"md-end-block md-p\"><span class=\"md-plain\">Not necessarily. If codec support, battery life, and build quality already meet your needs on a Bluetooth 5.3 product, there&#8217;s no functional gap that 5.4 alone will close. It&#8217;s most worth prioritizing for products with a longer planned shelf life or export markets where buyers actively ask about it.<\/span><\/p><h3 class=\"md-end-block md-heading\"><span class=\"md-plain\">What chipsets support Bluetooth 5.4?<\/span><\/h3><p class=\"md-end-block md-p md-focus\"><span class=\"md-plain md-expand\">Current-generation platforms from Qualcomm QCC and Airoha have solid Bluetooth 5.4 support, BES offers it on select SoCs alongside continued 5.3 production, and Jieli&#8217;s 5.4 adoption is newer and varies by model &#8211; worth confirming per SKU rather than assuming across the whole product line.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c377c75 e-flex e-con-boxed e-con e-parent\" data-id=\"c377c75\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\" data-core-v316-plus=\"true\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d5f24c7 elementor-widget elementor-widget-wpforms\" data-id=\"d5f24c7\" data-element_type=\"widget\" data-widget_type=\"wpforms.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<div class=\"wpforms-container wpforms-container-full wpforms-render-modern\" id=\"wpforms-178\"><form id=\"wpforms-form-178\" class=\"wpforms-validate wpforms-form wpforms-ajax-form\" data-formid=\"178\" method=\"post\" enctype=\"multipart\/form-data\" action=\"\/fr\/wp-json\/wp\/v2\/posts\/5449\" data-token=\"538ba8bda0f8aebc37cb7d56365001ad\" data-token-time=\"1785870572\"><noscript class=\"wpforms-error-noscript\">Veuillez activer JavaScript dans votre navigateur pour remplir ce formulaire.<\/noscript><div id=\"wpforms-error-noscript\" style=\"display: none;\">Veuillez activer JavaScript dans votre navigateur pour remplir ce formulaire.<\/div><div class=\"wpforms-field-container\"><div id=\"wpforms-178-field_0-container\" class=\"wpforms-field wpforms-field-name\" data-field-id=\"0\"><label class=\"wpforms-field-label\" for=\"wpforms-178-field_0\">*Name <span class=\"wpforms-required-label\" aria-hidden=\"true\">*<\/span><\/label><input type=\"text\" id=\"wpforms-178-field_0\" class=\"wpforms-field-medium wpforms-field-required\" name=\"wpforms[fields][0]\" aria-errormessage=\"wpforms-178-field_0-error\" required><\/div><div id=\"wpforms-178-field_1-container\" class=\"wpforms-field wpforms-field-email\" data-field-id=\"1\"><label class=\"wpforms-field-label\" for=\"wpforms-178-field_1\">*Email(We will reply you via email in 24 hours) <span class=\"wpforms-required-label\" aria-hidden=\"true\">*<\/span><\/label><input type=\"email\" id=\"wpforms-178-field_1\" class=\"wpforms-field-medium wpforms-field-required\" name=\"wpforms[fields][1]\" spellcheck=\"false\" aria-errormessage=\"wpforms-178-field_1-error\" required><\/div><div id=\"wpforms-178-field_3-container\" class=\"wpforms-field wpforms-field-text\" data-field-id=\"3\"><label class=\"wpforms-field-label\" for=\"wpforms-178-field_3\">Phone\/WhatsApp\/WeChat(Very important)<\/label><input type=\"text\" id=\"wpforms-178-field_3\" class=\"wpforms-field-medium\" name=\"wpforms[fields][3]\" aria-errormessage=\"wpforms-178-field_3-error\" ><\/div><div id=\"wpforms-178-field_2-container\" class=\"wpforms-field wpforms-field-textarea\" data-field-id=\"2\"><label class=\"wpforms-field-label\" for=\"wpforms-178-field_2\">*Enter product details such as model, color, materials etc. and other specific requirements to receive an accurate quote.<\/label><textarea id=\"wpforms-178-field_2\" class=\"wpforms-field-medium\" name=\"wpforms[fields][2]\" aria-errormessage=\"wpforms-178-field_2-error\" ><\/textarea><\/div><\/div><!-- .wpforms-field-container --><div class=\"wpforms-recaptcha-container wpforms-is-recaptcha wpforms-is-recaptcha-type-v2\" ><div class=\"g-recaptcha\" data-sitekey=\"6LcwpyMpAAAAAJRWcB_WdfQodkoDcUQv70yIYK-j\"><\/div><input type=\"text\" name=\"g-recaptcha-hidden\" class=\"wpforms-recaptcha-hidden\" style=\"position:absolute!important;clip:rect(0,0,0,0)!important;height:1px!important;width:1px!important;border:0!important;overflow:hidden!important;padding:0!important;margin:0!important;\" data-rule-recaptcha=\"1\"><\/div><div class=\"wpforms-submit-container\" ><input type=\"hidden\" name=\"wpforms[id]\" value=\"178\"><input type=\"hidden\" name=\"page_title\" value=\"\"><input type=\"hidden\" name=\"page_url\" value=\"https:\/\/www.tashells.com\/fr\/wp-json\/wp\/v2\/posts\/5449\"><input type=\"hidden\" name=\"url_referer\" value=\"\"><button type=\"submit\" name=\"wpforms[submit]\" id=\"wpforms-submit-178\" class=\"wpforms-submit\" data-alt-text=\"Send...\" data-submit-text=\"Send\" aria-live=\"assertive\" value=\"wpforms-submit\">Send<\/button><img decoding=\"async\" src=\"https:\/\/www.tashells.com\/wp-content\/plugins\/wpforms-lite\/assets\/images\/submit-spin.svg\" class=\"wpforms-submit-spinner\" style=\"display: none;\" width=\"26\" height=\"26\" alt=\"Chargement en cours\"><\/div><\/form><\/div>  <!-- .wpforms-container -->\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What Is Bluetooth 5.4 in Earbuds?
