MORE POWER AND ACCURATE SOUND DRIVEN BY AK4377A DACS & DUAL CRYSTAL OSCILLATORS

The power output of the all-new FiiO BTR3K is practically double the power output of the BTR3.

This light indicator displays the currently used format waste time keeping the track. It takes around 1.5 hours to fully charge the BTR3K while it gives you up to 11 hours of music playback. You can even charge the BTR3K while you are listening to music, all thanks to the USB-C Type C connector.

BEST PURCHASE EVER

This small amp/dac combo has absolutely changed how i work and listen to music. Being a bluetooth adapter is such a big plus, it does not limit me by the length of earphone or headphone, and the fact that you can use the inbuilt mic of the eaphone/headphone is a major plus, that means you dont have to clip the adapter near your neck, you can just toss it in your pocket and chill. The difference is there when you use it as a usb dac, it sounds way better than the normal audio output. Ability to connect 2 devices and switch between them effortlessly is also useful. A tip - upgrade the firmware version to 1.3 , then you can reprogram the volume up and down button, to a limited extent ofc. Very happy with this product 10/10 will recommend to anyone.!

Hey Akhil,
We thank you for this lovely review & we are glad you are enjoying it! Keep the music playing & Welcome to the Club.

Really good bluetooth receiver.

I was really skeptical about the power output figures, weather it would be able to drive my EX1 and Aria's however I was pleasantly surprised that not only can it drive them but there room to spare and that is out of the single ended output. You obviously cannot compare the overall sound quality to a desktop amp/dac but it does the job. Bluetooth connection is pretty stable upto 10 m beyond which it starts to distort. Hats off to Headphone Zone and Bluedart for the really fast delivery. I have bought quite a few products from them over the years and they do not disappoint with their delivery and customer service.

Thank you for sharing your review. We're so happy to hear that you've had a good experience with us.

Crazy convenience!

It's just amazing to hear what this little dac can do! I use it to wirelessly connect to my JBL stage a170 tower speakers via an amp. The amount of soundstage and details which this added was just mmmmm...apart from that I love the touch of uniqueness from headphonezone, it's my first purchase from here and it was a great one.

BTR3K - Best depending on usage

I own both the BTR3K and BTR5 so will compare both against each other.

My use case: Since new phones don't have 3.5mm output, I wanted something to play music, watch videos and take handsfree calls on my phone. I was only going to use either an earphone (Sony MDR xb55ap) or a regular headphone (ATH M40X).

Build quality - Amazing. No sharp edges, looks modern, small size, light weight. Can be easily clipped to shirt collar with the provided plastic clip. It is so light and small that in a few minutes, you forget it's even there. BTR5 is twice bigger and heavier. It is also small but not so small & light that you forget it. It is another device that you have to carry in your pocket.

Sound quality - Waaaay better than anything found in a phone/laptop/tab. If you haven't heard any other DAC/Amp so far, this will be audio nirvana for you. Good music separation, tight bass, wide soundstage, clear vocals, no background noise/pop.

Microphone - The microphone works as it should. If your earphone has mic, it picks up that. If it doesn't, it uses it's own mic. But since it will be on your shirt collar, it also picks up surrounding noise. So either use earphones with mic or bring it closer to your mouth which looks weird especially to others or take calls in a quiet environment.

Battery - Lasts a whole day easily from morning till late night.

Bluetooth range & latency - Depends on codec being used. LDAC has shortest range (one room only) but best audio quality. AAC has longest range (3bhk house) but worst audio quality. aptX is somewhere in between so pick as per your need. I mostly use LDAC and the latency/lag/delay is barely noticeable. It is there but only if you really notice. Pause and play again if there is delay in videos.

Value for money - Would have been perfect if Fiio had priced it 1K less but even at the current price, it is the best in the market for what it does. So okay there just not great.

Comparing with BTR5 - This is where it gets interesting. BTR5 has an objectively better sound quality. It is slightly sparkly in treble, has tighter bass and perfect timings on vocals and beats. It makes songs way more enjoyable and lively. BTR3K is laid pack in perspective, it is slightly warm, less tight bass and is loose on vocals and beats. And this is where it boils down to what you need. For long listening sessions (>1 hour), I prefer BTR3K. BTR5 sounds lively and immersive but it is so prominent and "in your face" that you can't focus on anything else. So, for my use case, where I wanted something to play music/videos on phone for long hours and still work or read/cook/run etc., the laid back sound of BTR3K is much better. It doesn't get fatiguing even after hours of music and the slightly warm sound is relaxing for videos/calls. Get BTR5 if you want to close your eyes, sit in a sofa, drown in music and do nothing else. Or if you have power hungry headphones. I now mainly use it as a DAC for my speakers in which it excels. If you plan to casually listen and work/study/run etc. BTR3K is better as its less revealing and fatiguing. BTR5 is better than BTR3K in analytical sound quality but it depends on your listening use case. Fiio has very cleverly designed and placed these products. BTR5 is well worth the extra price IF you have use for it and don't mind the DOUBLE size/weight/presence.

Headphone zone experience - Flawless. Delivered on time and the product is new. I even received some audiophile songs recommendations which is a good touch and sets them apart. Delivery updates were on time and accurate. Have been ordering from them and will again in future.

Hey Ayush,

Phenomenal Performance, Itty Bitty Package

This is my first foray into serious audiophilia. Please bear in mind that I am coming from a home setup of Marantz AVR coupled to Wharfdale Speakers.

The compact form factor belies the formidable build quality of this little gem. The chamfered front and rear glass panels bundled with the seeming solid aluminium body construction gives you a reassuring tactile experience. The buttons are uniquely shaped so as to make it easier to distinguish them just by touch.

The BTR3K does not come in your way of experiencing high fidelity, bar the multicoloured glowing FiiO logo. It's both encouraging to nascent audiophiles and scores coolness quotient for its minimalist vibe.

The way this FiiO delivers a phenomenal and immersive soundstage irrespective of the portable setup it drives is really eargasmic. I have listened to my collection of songs with the KZ ZEX IEMs and my Sony XM3s (in wired mode 😁). I must say the songs sound decongested, the music, more lively and the soundstage impressively wide.

Depending on the volume level you place the AMP/DAC at and the source of the audio, the battery lasts anywhere between 11hrs to 14 hrs as per my mileage so far.

Here's looking forward to many more ear tickling moments with the FiiO BTR3K. I would hands down suggest you to pick this up if your main usage profile is listening on the go and/or if you are like me taking your first steps down the audiophile rabbit hole.

absolutely almost perfect.

wonderful DAC, nice soundstage, accurate reproduction - the case could have been a metal ring with a clip instead of plastic - though it does act like a scratch gaurd. a must buy bluetooth accesory instead of a TWS or any other headphone.
