Well, these devices (both the BTR3 and BTR1k) are bluetooth rigs. As such, with the Iphones (which is what I have as well) they use the AAC codec for transmitting music, which isn't technically lossless right? But, assuming the iphone XS has similar output power to the iphone7 (which I have) the BTR1k absolutely provides a nice volume boost. It's a more powerful amp than the iphone's. Anything up to maybe 64ohm buds would be able to reach ear-shredding volume I'd think...

and even though it isn't lossless, it sounds very very good. Actually, I'd imagine the DAC in the BTR1k is probably better than the iphone dongle as well.

Great, thanks a lot, I think I'll buy it for Christmas.

Hi guys,

Excuse my ignorance but I can’t find this info anywhere. Does the BTR1K add anything to the BTR1? Doesn’t it have Aptx HD and/or LDAC for example? Or is that limited to the BTR3?

I thought the BTR1K was newer and therefore better specced but I could be wrong.

Dear friend,

You could read the comparison from the following form:

Best regards

My review of BTR1K is live now!

I actually made a 4-Way review on BTR3, BTR1K, uBTR and FiiO FB1.

The Audiophile-Heaven link has all of them together

I couldn't find the product page on Head-Fi to post the review here as well.........

I am disabled and use two btr1k’s for as much as 10 hours of audio at night. By my bed side, I have and Anker power bank and after 4 hours I switch to the second btr1k and recharge the first. I always have a refreshed btr1k ready to go. I get about 5 hours of battery time from a btr1k

I keep the iphone se volume at ¾ so the 32 volume levels are near the bottom or lower register. I listen to audio books and audm magazine selections.

For my music, when not horizontal, I use the fiio q5 and listen through fiio fh5 or fiio fa7 iem’s.

Actually that's a good idea. I just bought the uBTR but bought the BTR1K yesterday so I can listen to one and charge the other. I'm happy with both but the BTR1K does indeed sound better. I'm also amazed how small it is. Thought it would be much bigger.

What's the highest sampling frequency and bit depth Fiio BTR1K can manage when it is used as a USB DAC?

 

[Freemanix]

Hi!

Is there anyone who succeeded in using BTR1K as USB DAC under Linux? On Ubuntu 18.04, the device is recognized, but there is no audio from it when I switch it as main sound output.

Same problem on arch linux, recognize but no sound...

Dear friend,

Could the BTR1K work fine in Windows computer instead? And you are also using Ubuntu 18.04?

Best regards

I have recently purchased the btr1k, and i'm having some issues with it,
When i connect it to an avantree priva 11a transmitter, the avantree indicates that is transmitting aptx ll, but the btr1k indicates that it receiving only sbc, and the sound is very distorted.
I also have a mpow transmitter/receiver that supports aptx ll, and that is the same.
It works fine with my phone and tablet.
Anyone out there having the same problem ?, and any solution.

I've also got a weird problem with my new BTR1K.
It occurs when using apt-x and listening to quiet content like podcasts or slow songs with no background noise. Every time the sound is going silent because there's pause in the conversation or music, there is a crackling sound only on the left ear.
I tested it with different content, different headphones. Doesn't seem to happen in SBS or USB DAC Mode.
Is this normal ?

Dear friend,
There is a electronic switch in the BTR for avoiding the impulse sound which may provide pop sound. Actually, both channel would have this sound but maybe the left channel is more obvious for you.

Thanks for the quick response.
No, it's just the left channel. I tested it by switching the in-ears between my ears. Both my ears hear it only on the left channel.
I ordered a BTR3 to check, if there is the same behavior or if its a faulty unit.
