Разборка нескольких Bluetooth-3.5mm переходников для проводных наушников
- Цена: 2-5$
- Перейти в магазин
Захотелось подключить проводные наушники к ноутбуку по Bluetooth, заказал несколько экземпляров в ценовом диапазоне до 5$. В одном было заявлено чип [Qualcomm] QCC3008. В одном их них действительно есть поддержка AAC.
Первый экземпляр T66
https://aliexpress.com/item/1005006067102853.html
При подключении Bluetooth, название «T66»
Звучит хуже всех, такое чувство что он не может раскачать обычные наушники затычки, а может только в автомобиле передать звук в 3.5мм jack
чип www.zh-jieli.com/ Jieli JL BP1X678-56C4, это наверное AC6956C
Больше микросхем нет

Заявлено QCC3008
При подключении Bluetooth, название «BT001»
Звучит хорошо, на мой слух, звучит очень похоже на прямое подключение к макбуку.
Заявлено подключение двух устройств. Я попробовал подключить MacBook и iPhone, получается так, что если в настройках макбука стоит устройство для воспроизведения этот свисток, то с айфона невозможно услышать звук до тех пор пока на макбуке не переключить устройство воспроизведения на что то другое. (свисток подключение двох устройств одновременно действительно поддерживает.)
Разьем micro usb.
Внутри ожидаемо чип QCC3008:
Внутри
Нет, китайцы обманули, внутри DAJB14078
больше чипов нет.
DAJB14078 не гуглится, есть только это:

При подключении Bluetooth, название «ES-BT09»
Звучит примерно так же как и «BT001» (хорошо).
Чип C1618B от того же производителя что и «BT001», подключение двух устройств не поддерживает.
У чипа меньший размер в сравнении с «BT001»

Захотелось подключить проводные наушники к ноутбуку по Bluetooth, заказал несколько экземпляров в ценовом диапазоне до 5$. В одном было заявлено чип [Qualcomm] QCC3008. В одном их них действительно есть поддержка AAC.
Первый экземпляр T66
https://aliexpress.com/item/1005006067102853.html
При подключении Bluetooth, название «T66»
Звучит хуже всех, такое чувство что он не может раскачать обычные наушники затычки, а может только в автомобиле передать звук в 3.5мм jack
чип www.zh-jieli.com/ Jieli JL BP1X678-56C4, это наверное AC6956C
Больше микросхем нет

Заявлено QCC3008
При подключении Bluetooth, название «BT001»
Звучит хорошо, на мой слух, звучит очень похоже на прямое подключение к макбуку.
Заявлено подключение двух устройств. Я попробовал подключить MacBook и iPhone, получается так, что если в настройках макбука стоит устройство для воспроизведения этот свисток, то с айфона невозможно услышать звук до тех пор пока на макбуке не переключить устройство воспроизведения на что то другое. (свисток подключение двох устройств одновременно действительно поддерживает.)
Разьем micro usb.
Внутри ожидаемо чип QCC3008:
Внутри
Нет, китайцы обманули, внутри DAJB14078
больше чипов нет.
DAJB14078 не гуглится, есть только это:

https://aliexpress.com/item/1005006427441715.html
При подключении Bluetooth, название «ES-BT09»
Звучит примерно так же как и «BT001» (хорошо).
Чип C1618B от того же производителя что и «BT001», подключение двух устройств не поддерживает.
У чипа меньший размер в сравнении с «BT001»
