Bluetooth Headphone Amplifier - BTR1


Project background:
Back in August 2016, we had planned a Bluetooth headphone amplifier. In the earliest design, it has a headphone cable and is much smaller. To learn more about it, you may check this post
https://www.head-fi.org/f/threads/turn-your-detachable-cable-headphones-into-hifi-bluetooth-headphones-fiio-btc-mmcx.817539/

And during the design process, the product shape has changed quite a lot. It's mainly because the small size design could not meet our requirement for the high sound quality. So we have aborted the design of integrated headphone cable and upgraded the project to the BTR1, which has a 3.5mm headphone port and is more applicable. What's more, since the short headphone cable is not everybody's choice, we eventually decided to sell the cable separately and will not supply it as standard accessory. This very first short headphone cable is applicable to the MMCX connector headphones, including our F5.

Main features :

1. Bluetooth 4.2, supporting SBC, aptX, aptX low latency
(Good compatibility: compatible with Android, iOS and many other types of devices)

2. Discrete high-performance DAC chip, up to 48kHz/24bit decoding support, designed additionally with high-performance work mode
(SNR≥95dB, far better than average Bluetooth receivers, free of background noise even when connecting to high-sensitivity headphones)

3. Supports Bluetooth voice calls, with built-in omnidirectional microphone
(Equal to smart phones' built-in microphone, which makes you enjoy high-quality phone calls)

4. Rechargeable Li-on battery, with around 9 hours' battery life
(Around 9 hours in normal work mode, and around 6 hours in high-performance work mode <Will also adjust>)

5. Working status indicator (Blue + Red) and discrete audio effect indicator
(Remotely switch the audio effect without taking out your phone, easy and convenient)

6. Metal clip design and lanyard
(Easily clip to your collar, bag straps or anywhere)

8. Bluetooth effective range: around 10 meters

Very interesting product. I would really like a mobile replacement for my Fiio E10k, but with bluetooth and the same nice sound quality.
The BTR1 is very similar to the Bluewave GET https://www.bluewaveaudio.ca/?v=3a52f3c22ed6
But the GET offers also APTX HD and AAC. Can you include especially APTX HD?
I also would like an even longer battery life. A somewhat bigger size would be ok.
Can you charge and play back at the same time?

Very good products, thank you for providing product reference, the next generation of Bluetooth products will support APTX-HD, but the current BTR1 does not support, just aptX, aptX-LL

Fantastic, mounting it onto over the ear headphones is exactly what I'm looking for!

Together with an aptx LL transmitter with optical in (e.g. Avantree Oasis) I can finally get rid of my Sound blaster E5 which is way too heavy for that.

Edit: what impedance are you designing this for?

You may op for Q5 for longer battery life I supposed :)

Looks very interesting - essentially what I have been looking for. As @gzahl said, similar to the bluewave get, and similar launch windows as well, so excited to give both a try. That said, FiiO has earned a lot of good will from me, so all things equal, this might be my next buy.

Very interested and will likely get this even though I do plan on getting the Bluewave get as well. For future consideration, is it possible to allow codec selection? With the BW get, it's aptX HD but I was told it's backwards compatible with LL (just can't do both at the same time). The use case I was thinking of was I'd like to watch movies occasionally on LG V20 but would like it to utilize LL instead of HD for those occasions. Hopefully your next iteration would allow this and feature Class 1 range too. ^_^

P.S. Any specials for pre-orders?
