Article Review 


How’s the sound and power compared to that ifi? 

Not even close on power to the ifi. Different devices and physical sizes. Sound quality is ahead on the ifi too

When it is secondary pair. Is it automatic or manual?

It will pair automatically, theoretically.

Can this power the Senheizer HD598 ?

According to numbers, HD589 are pretty sensitive, so there shouldn’t be any problems, but unfortunately, I didn’t test in practice, so I can’t be 100% sure

Is BTR3 paired with android smartphone has battery level for this device?

Actually. BTR3 shows battery status on iOS, but I’m not sure if it’s supported on Android

also, BTR3 got new FW with remote control via FiiO Music app, I think it can display battery status (but I didn’t tested new FW yet)

Can i use the Fiio e10k or the btr3 with car to improve the sound quality?

Actually, it depends on your car stereo system. if it already has good bluetooth module, BTR3 won’t give big improvement. and if it doesn’t, then you can improve sound with it. 

Which sounds better the shanling m0 or fiio btr3?

In wireless mode BTR3 is better, but M0 is a bit better playing files from local storage, especially on treble, as it’s affected by wireless codecs most of all. 

Did you say LDAC is better than wired connections?

No, I said that it can be sometimes (if headphones out isn’t good), but not more

Is it neutral or warm sounding?

Definitely not worm. closer to neutrality, as much as it’s possible for bluetooth device 🙂

How does it compare to the BTR1 and the Cozoy Takt Pro? 

Tiny bit better then BTR1 on aptX and noticeably better with LDAC/aptX HD

Takt Pro is noticeably better (not huge difference, but it’s audible)

Can you please tell, which one has more power (louder), BTR3 or BTR1K? 


≥ 25mW (32Ω/THD<1%)

≥ 45mW (16Ω/THD<1%)


About 25mW (32Ω loaded)

About 33mW (16Ω loaded)

Can tell me does it boost the Volume output of the earphones / headphones ?

It’s a bit more powerful then regular smartphones, but there won’t be huge difference

Does this work with a bluetooth cable like the trn bt10? 

No, it’s a receiver, not transmitter

How do you compare it with fiio BTR1K which one sounds better?

if your player/smartphone supports aptX HD or LDAC, then BTR3 will sound better. otherwise, there won’t be big difference.

Headfonics Review 

Build Quality

Form Factor

The BTR3 is marginally taller but not quite as wide as the BTR1. It weighs 6g more at 26g compared to 20g but the difference in the hand is negligible. If anything, the BTR3 just feels a bit more solid.

The form factor seems more in keeping with a premium version of their very cheap uBTR dongle than the BTR1. Gone is the ribbed lightweight aluminum 2-piece shell and in its place is a black aluminum and a very attractive 2D glass variant of the white plastic uBTR design.

2D Glass

I have seen a few 2D glass designs before on Shanling and HiBy DAPs and they are always visually striking. What I like about the BTR3 glass is the resistance to fingerprints (oleophobic as FiiO term it). You will be hard pressed to leave an oily smudge anywhere on the BTR3.

Behind the 2D glass, you do have a small amount of visual information in the form of a LED powered “FiiO” logo that changes colors to denote various status changes and an NFC logo at the bottom for NFC status alerts.

Spring Clip

The back has a similar spring clip and lanyard system as the BTR1 and uBTR and it does come with a black nylon strap to allow you to hang it from your neck should you wish to do that. The finish is a smoother black metal finish compared to the brushed black of the BTR1 and all-white plastics of the uBTR.

Headfonia Review 


BTR3 supports basically every codec out there. There are a few performance-related differences between them, but overall, as long as it receives signal, the BTR3 amazes. It also works as a USB DAC, and sounds great in that role. Measurements linked were made in SBC, AAC, and LDAC modes. As you can see from the screenie below and the information in the linked article, BTR3 is pushing the bounds of portable audio. There are dedicated audio players that measure worse. There are dedicated audio players that output less voltage. Damn good. 

I really wish that BTR3 bested the BTR1 in every non-audio respect. If only it had the latter‘s connection quality. Both return near-black backgrounds, though BTR3 hisses even less than an iPhone SE through Campfire Audio’s super-sensitive Comet earphones, making it the least hissy Bluetooth DAC/headphone amp I’ve yet tried, if not one of the least hissy devices in the audio mass market. FiiO nailed it. 

BTR3 bests uBTR in every unloaded audio metric, and even the amazing BTR1 in most measures, including less than a third of its IMD and noise. Not bad. Not bad at all. Under load, some of that is reversed; Note that in all modes I’ve tested, it shows a bit of high-frequency roll off. Honestly, if you hear it, you might like it. When done right, lowpass filters sound great. And honestly, BTR3’s lowpass filter is genius. 

One thing I really dig is how well the BTR3 portrays stereo gradations. At first I thought it was too central, but the more I listened the more I realised that it was that stereo bands are detailed and allowed to fade to the sides rather than present a wall of equal pressure sound. This style makes for a deep, nuanced sound stage whose lateral cues are delicate and fine.

A Portable Mindset

Flagship digital audio players (DAPs) and smartphones are getting larger and heavier, burdening pockets until a solution is found. 

Enter the FiiO BTR3, a Bluetooth receiver and amplifier, now in its third iteration (I must have fallen asleep for the first two). At 25g and just the size of a thumb, it turns your portable setup into a lightweight solution, so you carry just the BTR3 and earphones and stay active while your DAP/smartphone rests nearby.

The BTR3 also carries a slew of secondary functions. It receives calls with Qualcomm’s cVc noise cancellation technology. It converts car and computer speakers to Bluetooth receivers, playing music wirelessly from your smartphone or Bluetooth-enabled DAP. It can also be used as an external DAC (digital-to-analog converter) for your laptop or computer, instantly improving sound quality via its dedicated AK4376A DAC chip.

Thenextweb Review 

Fiio’s BTR3 is a gadget made for the former. It’s a thumb-sized Bluetooth receiver that allows you to connect your old wired headphones to your jack-less device without a dongle, but it also sounds better than most phones or laptops with a headphone jack too. It’s an altogether attractive package: It costs $70, is built by reputable brand known for its portable amplifiers, and comes with class-leading codec support.

By class-leading, I mean it has every significant Bluetooth codec: SBC, AAC, AptX, AptX HD, AptX Low Latency, LDAC, and even Huawei’s new LHDC are all on board (AptX LL and LHDC are particular rare). I’m not about to start an argument on which codec is the best, but that’s the beauty of the BTR3: you can choose whatever you like. Even the “never wireless” crowd should be satisfied, as the BTR3 can still be used as a wired dongle via the included USB-C cable.

I personally stuck to LDAC for most of this review, but tried all the other codecs too. The BTR3 actually lights up a different color for each codec, which is a small but welcome touch in case you’re not sure what codec your device is transmitting. The BTR3 uses Qualcomm’s latest Bluetooth chip and provided as stable a connection as I’ve gotten from a wireless device; I didn’t see any significant dropouts in a couple of weeks of testing.

Moonstar reviews

Hardware and Functionality:

The FiiO BTR3 sports a Qualcomm CR8675 Bluetooth Chip and an Asahi Kasei AK4376A DAC with build in amplifier. 

  1. a) Bluetooth Chip:

The Qualcomm CR8675 Bluetooth chip used in the BTR3 is a premium low-power solution designed for enhanced audio applications with support for 24-bit transmission and processing, thanks to its 120MHz DSP. This chip is also much more stable in signal strength than other competing chips, especially in situations with lots of interference.

  1. b) DAC and AMP Section:

The AK4376A is a compact DAC with a build in headphone amplifier for portable audio products. It has some nice specs such as -107dB THD+N and signal to noise ratio (SNR) of 125dB.

  1. c) Drivability:

The FiiO BTR3 has a power output of 33mW@16 Ohm & 25mW@32 Ohm, which makes it loud enough for IEM’s with an impedance between 8 to 60 Ohm (HiFiMAN RE800 Silver). The BTR3 was also able to drive my full sized headphone the very popular Audio-Technica ATH M50 to very loud volume levels.

Primeaudio Review ( FiiO BTR3 vs Radsone Earstudio ES100) 


FiiO BTR3 vs Radsone Earstudio ES100 ($99 USD)

This is one comparison that everybody has been asking for and understandably so, considering these are the 2 major players for Bluetooth receivers in this price segment.

First of all, let me say that they both sound fantastic and there’s very little difference in actual audio quality. To my ears the BTR3 sounds just a tad more vivid and has more note density but that could possibly be a result of stored settings from the Earstudio app (crossfeed, digital filter etc.)

The FiiO unquestionably has a more premium build with its metal chassis and 2.5D glass front. Its clip has a better grip too, making it feel more secure when attached to clothing etc. That’s not to say the ES100 doesn’t have its own charm. If I were forced to make a choice between the 2, I’d probably have to flip a coin because I genuinely love them both.

For anyone who’s not sure which device suits them best I would say this: If you need to drive high impedance earphones or headphones then the ES100 is the better choice for you (requires balanced cable). Similarly, if you’re a control freak and demand EQ functionality and a multitude of tweaks then again the ES100 is the way to go.

If you’re the type who wants a simpler plug and play experience then the FiiO BTR3 would likely be your best choice. The BTR3 arguably has a better button layout than the ES100 and it supports a couple of rarer codecs such as aptX-LL and LHDC. One more thing worth mentioning is that the FiiO costs around $30 less.

Informinc Review ( Want to know the Pros and cons?) 

What are the pros and the cons?

There are plenty of things to like about the BTR3 and here are the most important ones:

  • The broad codec support
  • The high-quality audio performance
  • It comes with a built-in microphone
  • The battery lasts for a good amount of time
  • You get support from Siri
  • It’s easy to carry around
  • It has a nice looking and tough body and build
  • It’s easy to pair
  • It’s easy to adjust the volume

The downsides aren’t deal breakers from our point of view, but it’s always better to have the full picture:

  • Not everyone goes for its flashing logo
  • The placement of the USB port and power could be better
  • The lack of Line out in USB mode
  • The USB file resolution support isn’t the best Review 

Three things have occurred in the realm of Bluetooth specifically at the right time to support this. 

The first was the mass adoption of streaming standards and codecs from Qualcomm and Sony. 

These are in the form of Qualcomm AptX/AptX HD and Sony’s LDAC. While these aren’t new, they have only since mid-2017 been hitting the mass market hard. 

The second is the release and wide smartphone adoption of the Bluetooth 5.0 standard; the most pertinent thing for audiophiles here is the increased bitrate transmission to 2Mb/s. 

Lastly, is smartphones in 2018 running the latest iOS and Android supporting all of these together right out of the box. 

Thanks to a strategic move from Sony, all versions of Android starting with 8.0 Oreo will come with the LDAC codec built into the source code; the pesky licensing is all dealt with here. 

Qualcomm’s AptX is another story but most devices are coming with support for that as well through paying a licensing fee.

All these factors combined create a fusion of the right time for high-quality wireless audio to hit personal headphones. 

Headphone jacks disappearing off smartphones is also a key point here and has helped further the ‘need’ for a Bluetooth amplifier for your portable headphones. 

Ilounge Review 

Right out of the box, one thing seems clear: Fiio is abandoning the BTR1’s design language in favor of the clean looks of the μBTR. 

The BTR3 is, like the μBTR, a small rectangle with rounded edges. Its materials and build quality, however, are fully upgraded, with a full metal housing and rear clip and glass front — a welcome improvement on the μBTR’s easily-scratched acrylic. 

It’s heavier and larger than the μBTR, but at 26 grams and 58mm x 25mm x 10.4mm, the BTR3’s weight and size are still negligible. 

All controls are on the side — clicky buttons for power/pairing/mode and play/pause and a rocker switch for controlling volume/track control. 

Like its predecessors, a microphone is also included for wireless calling. Inside the BTR3 is a 300 mAh battery that charges in about 90 minutes and lasted about 10 hours in our testing. 

Two Bluetooth devices can be paired a time; double-clicking the power button toggles between them. Unlike the μBTR, the BTR3’s headphone jack and USB-C port are both on the bottom of the device. This can be a bit problematic in practice, since it can be impossible to use both with anything other than the included USB-C cable and a low-profile headphone plug.


The FiiO BTR3 has two of the most diffused and standardized ports: a 3.5mm audio jack and a USB Type-C for charging and for USB DAC mode. Both connectors are placed on the bottom of the unit, the USB port is on the right edge and the 3.5mm jack on the left edge.

This allows the FiiO BTR3 to transform into a wireless Bluetooth device any headphone, earphone, speaker, home audio and car audio system – using a 3.5mm cable. For example, if you ever wished a wireless Meze 99 Classics or 1MORE Triple Driver Over-Ear, now you can simply connect them to the FiiO BTR3 and have a Bluetooth Meze and 1MORE over-ear headphone.

As mentioned before, this is not only limited to earphones and headphones, you can also use the FiiO BTR3 with your wired home audio/home theater system/speaker and with your car audio system to transform them into a wireless system.

The FiiO BTR3 is equipped with a Qualcomm CR8675 Bluetooth chip, a low-power model with a 120MHz DSP which supports 24-bit transmission and processing. Moreover, the brand grants 30 meters of Bluetooth transmission (on open areas), which is 3 times more than the standard 10 meters of most Bluetooth devices.

More than obvious by now, the FiiO BTR3 can be paired with any smartphone, tablet, PC/Mac and device that can connect to a Bluetooth receiver/amp.
