Anyone interested in the King Pro, might want to take a look at the $59 "2019 My Love Limited" model. Apparently it uses the driver from King Pro, 55 ohm impedance does kinda support that claim. Available at penon: https://penonaudio.com/tfz-my-love-edition.html or Ali tfz store...

Nice !! Any info on when these will be available ?

B pin for C16/AS10, C pin for CA4/ZSN/ZS10 Pro

If only they'd gotten rid of the ceramic antenna. Choppy connection is pretty much the only major downside in an otherwise excellent cable.

@FiiO is there any plan to release a RC-BT v2 ? Perhaps with QCC3005 chip, 130mah battery and 2 Pin option ? I really love the RC-BT, they are the only ones in my collection of > 20 bluetooth cables, which have low enough noise floor that 16 ohm earphones don't hiss at all. I've even done a bit...

Ah ! thanks for pointing me towards the right direction.

Not sure if this is the correct thread, but has anyone used mmcx to 2 pin adapters ? They seem real useful. https://www.amazon.com/connectors-Conversion-Connector-OKCSC-Converter/dp/B07CZD93LN https://www.amazon.com/0-78mm-Cable-Adapter-Westone-Tralucent/dp/B07C4R3P9S...

It does support AAC and AAC-LC, as seen in this hcidump output, for the "A pin" one I got. $ sudo hcidump avdtp HCI sniffer - Bluetooth packet analyzer ver 5.44 device: hci0 snap_len: 1500 filter: 0x400 < AVDTP(s): Discover cmd: transaction 0 nsp 0x00 > AVDTP(s): Discover rsp: transaction 0 nsp...

Usually the reply is that discrete DAC and bigger battery to power the extra electronics is not possible in a adapter cable. But it might be doable in a Samsung Level U type form factor where the bulk of the neckband housing is behind the neck. If Fiio did launch a MMCX adapter neckband with...

@FiiO does the CSR receiver chip in BTR3 improve bluetooth connectivity over BTR1 ? My BTR1 range is poor, and loses connection with the slightest obstruction in los.

On average how much playtime do you get on a single charge ?

Interesting. I got the impression from this infographic.

Correct me if I'm wrong here, but isn't the Shanling M0 limited to SBC and LDAC only when receiving ? Unless one has a Android oreo device with LDAC set to default from developer options, they'd have to use SBC, no AAC for iDevices either.
