  • Near-Audiophile sound. Awesome build quality.
Dollar for dollar, the FiiO BTR3K has dramatically exceeded my every expectation! ...and I have reasonably high expectations... although not true audiophile. Oh, and it's sooo TINY. The build quality is amazing. Feels like a tiny little glass brick. I have this device paired to an LG V60 Android phone which fully supports all of the HD codecs like APTX HD and LDAC. I run the BTR3K in either APTX HD or LDAC (see below for a pro tip on getting this configured properly). Hanging off of this device are my 1more quad-driver, THX-certified in-ear headphones (best sound for the money, IMHO) with Comply foam ear tips for near-perfect comfort and sound isolation. Using the exact same headphones, the sound quality (especially in APTX HD or LDAC mode) rivals my portable USB DAC/Amp (a FiiO E18 Kunlun), maybe even exceeds it in terms of apparent clarity and soundstage. Of course, even in APTX HD mode, the DAC on this can only receive 48KHz, 24bit (essentially CD quality) data, so don't expect 96K levels of ultra-fine fidelity. That is just a limitation of Bluetooth bandwidth, not the BTR3K. As previously stated, the sound quality is amazing and, unless you are trying to drive really power-hungry cans, the volume levels are more than sufficient to cause hearing loss. A note here is that, unlike most Bluetooth 'headphones,' the volume control on these is completely independent of the source, at least on my LG. This allows you to run the BTR3K at lower volumes (raising the volume on the phone end) and conserve the battery life... which by the way is already amazing on its own! The included little holster is really well-made and allows you to clip it to your shirt to take full advantage of the built-in microphone. I am pretty sure that the BTR3K overrides the mic on my headphones. Just be advised that this little toy is HEAVY for its size and will drag down on your shirt collar. I place mine off to the side so that it is riding more on my shoulder/collarbone than dangling from my collar. That seems to work pretty well. PRO TIP #1 (see attached screen-shots): On Android 10 you need to modify your connection in Bluetooth settings (not the fancy developer-mode override, which requires a phone reboot every time anyway) to set the BTR3K Connection Type to 'Best Audio Quality.' This will give you APTX HD (if your phone or other source supports it) or LDAC. If your Android phone supports both APTX HD and LDAC, you will need to use the developer options to force LDAC if you want it. This is because Android prioritizes APTX HD over LDAC. You can tell which codec you are connecting through via the color of the little FiiO light on the BTR3K (when the source is actually playing). Yellow = APTX HD, Light Purple = LDAC. PRO TIP #2 (see attached screen-shots): If on Android, you absolutely should download the app called Neutralizer which allows you to set up each different headphone/connection combo to be as absolutely as 'true' to the music as your gear can handle. It uses a simple little hearing test, at various different frequencies, to allow you to literally 'dial in' the perfect balanced sound, regardless of how your headphones (or ears) were tuned from the factory. This is especially important as different codecs and DAC/Amp hardware can change the sound characteristics of your headphones A LOT. I have totally different profiles for my 1more's connected directly, via my USB DAC/Amp, and via the BTR3K. Same exact headphones. Three fairly different Neutralizer profiles. Sadly, I do not yet own a set of balanced headphones, so I can't speak to the fact the BTR3K has direct support for 2.5mm balanced headphone outputs driven by discreet DACs and Amps. I just have not been able to make myself spent the $1,500+ for a good set... yet. I do not doubt, however, that it can live up to that challenge. Just make sure that they are not too power-hungry. Anyway, hope this review helps. Happy Listening! - Matt ... show more

  • Excellent sound quality, super small size
Excellent sound quality, small size, and all the features most people need. Battery life is good with AptX HD and LDAC (I haven't tested SBC or AAC). Bluetooth stability with the newest firmware is solid. The AKM DACs sound slightly warm compared to ESS DACs without some of the weird pops and crackles at higher frequencies that I've experienced with ESS DACs. The choice of DAC is the main reason I bought the BTR3K over the BTR5K and BTR7. The power output is more than enough to drive all of the IEMs I have as well as the headphones that I rarely use. I highly recommend this portable DAC/AMP for people who primarily use IEMs or easy to drive headphones and prefer the AKM sound. ... show more

  • Great Product, unless you buy from Quality Photo Inc.
This product was exactly what I was looking for! Something I could listen to music with my over-the-ear headphones, since my phone doesn't have the headphone jack. It worked FANTASTICLY for a few weeks and I loved it so much. The volume control is a bit weird like some other reviews mention, but it's fine once you get used to it, same with the other controls. The sound quality was pretty decent with my headphones for a Bluetooth receiver in this price range I'd say. No real complaints about the product at all. The issue I faced is I bought from a seller called "Quality Photo Inc." and the product became defective after a few weeks of use. As in it would connect with to my phone's Bluetooth but wouldn't play any sound other than the "power on/power off" voice. When I tried connecting it to my PC's Bluetooth music would play, but it would be so choppy and low quality it was unlistenable. I tried to contact "Quality Photo Inc" for support about my defective product on Oct. 13th. Today is Oct. 30th, and to this day, I have only received automated support messages. This seller does not care they sent a defective product. Luckily, Amazon fixed that issue for me, but the seller should have had to do that. The seller totally ignored me. Overall, the FiiO BTR3K Receiver Amplifier Bluetooth Headphone Amplifier is fantastic! especially for the price. I'm sure FiiO is a great company with other great products! Just be careful which re-seller you buy the product from, so you don't end up like me with a defective product and no way to get a replacement. ... show more

  • Great sound
Before last week I didn’t know such a product existed. I wanted a pair of great Bluetooth headphone for home listening with an iPhone but after looking at nearly everything out there it seemed like there was always a trade off between sound quality, build quality and price. Then I stumbled across this and read the reviews on some audiophile websites. My problem is solved. I’m not a technical listener, I just know what sounds great to me, and these process music amazingly well. The sound using an older pair of B&O wired headphones is incredible to me. Setup is easy and it pairs flawlessly. Another great thing is the price. Now I can upgrade to new technology without having to ditch a pair of $400 wireless headphones when they are obsolete. The only wish would be for a slightly bigger battery. Granted, this amp lasts all day for me but I would still make the trade off between a slightly bigger size for a few more hours of use. Also, the app works fine but it could use some refinement and maybe a parametric equalizer or less extreme presets for the equalizer. I almost bought the BT5, but for my purposes and ears there is no reason. ... show more

  • Sounds great
I manage a small venue. When customers want to play some music, it was always the Android/Apple plug game. A customer came in with one of these and it sounded good and was easy to use and control. I bought it the same day. Works great.
