I've been using one of these devices for about 6 months now and it is pretty great. I bought it mainly because I can't deal with wires running from my phone to my earphones. I always snag the wire and have wrecked many earphones that way. I use LDAC to stream music from my Sony phone to the BTR3K, sometimes it is my FLAC files sometimes it is music from Qobuz and elsewhere. LDAC streams data up to 990kbps, it is great for music. I doubt many people could discern music streamed over LDAC from music played using a wired connection. Audiophiles do use these devices, at least those that are up to date with technology. I live in a busy city centre, I don't get any interference or drop outs, I sometimes get those problems with bluetooth earbuds. The device runs all my IEMs and headphones using 3.5mm SE. If you have any of the rare insensitive IEMs you may need to use a 2.5mm balanced cable. I bought the BTR5 a month after I got this, they are great devices.

very thorough and informative video, good work

The difference in sound quality is very noticeable, even when plugged into my PC and used as a USB sound card. There's also the BTR5 which is even better but twice as expensive. Definitely want to pair this with a good pair of headphones or you're wasting your money.

Has it enough power for 250 Ohm DT 990 PRO in an acceptable volume? I use them with a Monoprice Desktop DAC at the moment which works fine. I tried the Sharkoon Gaming DAC Pro S for mobile use but the Volume was just to low. Thanks

lmao that live drop test 🤣 great review 👍

Hi. Thank you so much for your review. I'm new into these "better audio world". I need help in deciding whether I should purchase a FiiO BTR3K or a Truthear SHIO.🙏🏻

can i use it with my old active speakers (microlab solo 7c) and pair them with poco x3 pro ? will i get a good quality sound out of them ? plz help me out.....

Thanks a lot for the review! Do you know if you can use it while it's charging? Thanks!

Mine btr3k can be fully charged and within 5 minutes it will say 80% Battery then every hour after that it will lose 20% Battery . I've had it for years now and only just recently started back using it again so this makes no sense. I have the BTR7 in a clip case but it's so heavy . I'm thinking I might buy the BTR5 2021 Version To Replace The BTR3K .

I just got this thing and it's already in the box headed back to Amazon. It was low and muffled. I got a Hiby FC3 and it sounded way better. Also, I have a Hidizs Ap80 pro dap which connects over Bluetooth to your phone and that sounds a lot better streaming Ldac. The Fiio sounds like a cheap $9. dongle.

Does it last long, Quality wise? Cause i was contemplating between this and ugreen bluetooth adapter, which is considerably cheaper, but ive read reviews that ugreen breaks after a few months. So maybe shelling out more money will be worth it. I dont really care about the diff in sound quality, im just tired of dongles breaking and have to keep buying again.

I know that btr5 is better than btr3k however does the btr3k better than shanling up4 v2022? why? thank you

Thanks for the video, really helpful. I had a Fiio K2 in the past, however I have a question! I am looking for a new phone, and of course, no phone supports headphones anymore, like you already said in your review. I am not that much in too audio, but I just wanted to look for a solution that makes my IEM-headphones usable with a new phone. My only issue is, I sometimes use my headphones for calls. My best friend moved, so we still have regular calls. I am assuming the Fiio BTR3K takes a signal from my phone and plays this as music, but it cannot send back the music from a mic on the headphone cable? Or would this work? If that works this would be THE solution for me.... If it doesn't I'll have to look on for another solution. Thank you for your time.

It almost feels like.. he is feeling drunk in between.. but awesome review.

Hello. Can I connect it via bluettoth with my hires sony walkman nw a35 player that uses all codecs or is it only for android phones?

When I Use The BTR3K As DAC for Wired Listening I Notice It's Not As Impactful As My Hidizs S9 PRO DAC AMP DONGLE at the same volume

Is it worth buying to use connected to minijack (aux) in my car?

Hi there ! Thank u for the review. Can I use it in my car to boost the sound from AUX? Basically when I use AUX cable, the volume is very low even when I put it on max. CD volume is ok, but when I connect AUX it offers me much worse volume and quality.

Sir can you also use TWS earbuds with the Fiio BTR3K?

Hi, how is the microphone quality? Can we use for calls ? Noise cancellation any good?

Will i be able to use a beyerdynamic dt 700 pro with this device?

does it can transmit LDAC over bluetooth? Im using Apple product (ALAC) and i want to connect to BTR3K (convert ALAC to LDAC) -> bluetooth -> sony headphone (LDAC)]

Now it's impossible to find for under $100

05:08 are you sure our phone has to support these codecs? been thinking to buy this BECAUSE my phone does not supprt the codecs

where you get high res songs?

Is there a difference in quality if you use this to listen to music streaming e.g spotify, compared to using FLAC local files when they both have to be transmitted to the bluetooth using the respective codec formats anyways?

I have a cheap smartphone with a ton of 128/192 kbps mp3s and a soundcore q30. Would a fiio would improve my quality of the music or would be a waste of money? Thanks

How does it compare to the old Fiio BTR3?

Its BTR3K not BT3RK

It’s rubbish. You & the other reviewers must be on a bung from Fiio. Bought it & sent it back. Avoid & spend another 10O bucks on the ifi blu
