終於到
唔知呢度有冇人拎TWS黎開會(laptop, ms team),呢度可以順便集思廣益
手上有jabra evolve 2 75, wh1000xm5, souncorD L4 Pro, soundpeat air3 deluxe hs, 新加入az60m2
notebook係win10, bluetooth5.1, HFP 1.7 (應該係)
基本上呢堆TWS用bluetooth同notebook connect, headset microphone default最多都係出到1 channel 16kHz (應該係HFP問題)
mic performance基本上唔可以用黎一般講電話黎比較
暫時試過將呢堆耳機同jabra link 380 dongle (BT5.0) 試,唔知係唔係dongle BT太舊(對比呢啲耳機既BT ver),基本上冇因為dongle microphone performance有比較好
應唔應該買個BT 5.2 (BTD-600)黎試下

jabra evolve 2 75 (BT5.2)
wh1000xm5 (BT5.2)
L4 Pro(BT 5.3
air3 deluxe hs(bt 5.2)
az60m2 (BT 5.3)
