(Note: Currently, there is a 1\/3000 proportion of cases where loud speakers cause the motherboard to restart, and the copper wire that costs over one yuan is very thin.) There are no other reasons besides this.\u003c\/div\u003e\u003cdiv\u003e② How to pair? ---Disconnect the phone, turn on the speaker, quickly press the power button three times to start a team - wait for 10 seconds to search for Bluetooth connection again. The initiator of the team is the left channel. Four hits cancel pairing.\u003c\/div\u003e\u003cdiv\u003e③ The sound feels very low - very few, the phone needs to enable Bluetooth volume synchronization function - Settings - Bluetooth - Expansion - Check volume\u003c\/div\u003e\u003cdiv\u003eSynchronize or absolute volume, or connect a touch switch control on the reserved volume pad on the motherboard.\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003eProduct List:\u003c\/div\u003e\u003cdiv\u003e1x module\u003c\/div\u003e\u003cdiv\u003e2x speaker cables (optional)\u003c\/div\u003e\u003cdiv class=\"detailmodule_html\"\u003e\u003cdiv class=\"detail-desc-decorate-richtext\"\u003e\u003cdiv\u003e\n\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf8e5e65e9a3e4e5190e9ffe2524bba94j.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sc9bb0cfabbd74846a10c9cf02af0ea85S.png\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S929cfbea721b4a0bbc0b6ed7e294a706A.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Seefd41f8abfe4177acca0450eaae842b6.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S4e9a6ee14b994c29bc87545ecc0df5349.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sd0d64de58bd04d7da495c301f69818afk.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S99b568b2ea6948c587abab9316120fe1K.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sd9a7079f216d4817ae6542dc28841d5aR.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sa82fda956f4747e7856b45c1f45ee1a5B.jpg\" slate-data-type=\"image\"\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"Board 2x10W","offer_id":55506296865067,"sku":"14:1202#Board 2x10W","price":16.52,"currency_code":"USD","in_stock":true},{"title":"Board speker cables","offer_id":55506296897835,"sku":"14:4044226#Board speker cables","price":17.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/Sf8e5e65e9a3e4e5190e9ffe2524bba94j.webp?v=1788929691","url":"https:\/\/yoeruyo.com\/products\/dc-3-7-5v-tws-stereo-bluetooth-power-amplifier-board-dual-channel-high-sound-quality-2x10w-output-sound-module-supports-charging","provider":"Yoeruyo","version":"1.0","type":"link"}
