FiiO BTR5-2021 Headphone Amps Bluetooth 5.0 Receiver High Resolution 384K/32Bit Native DSD256 USB DAC Supports LDAC/aptX HD/MQA for Smartphones/PC/Laptop/Car/Home Audio (Regular)

In general, I've been a fan of FiiO audio gear ever since I first got into higher end headphones, and prior to getting the BTR5, I had been daily swapping between a FiiO BTR3, and a much cheaper "Konecta Soundwhiz" bluetooth receiver. I am not a fan of being tethered to my desk, so I would just kinda use one of them until it died, and then I'd swap it out for the other. I was using these to drive my pair of Sennheiser/Massdrop HD 58X most of the time, and occasionally my Monoprice M1060's, and while there was a subtle improvement in terms of clarity on the BTR3 compared to the Konecta, the difference was very slight, and it ended up not really being a meaningful improvement. On top of that, the cheaper Konecta receiver also clearly was able to output at a higher max volume, which furthered my very lukewarm general opinion of the BTR3. It's a fine product, but battery life was pretty dismal on big cans, and in general, I have found that there are cheaper products out there that perform nearly identically.So when I saw Z Reviews' video on the BTR5, I was immediately interested. FiiO really seemed to understand all of the small things about the BTR3 that were holding it back from being truly excellent. And now, after over a month of use, I can say without any reservations that the BTR5 is the best execution of this type of product I have ever used, by a wide margin as well. The BTR5 has a very noticeable larger battery, giving me what feels like nearly double the battery life of the BTR3, and all the while, it is doing it while being able to output at significantly higher levels of power and clarity. I also have an xDuoo XP-2 BT receiver/dac/amp, which is a significantly larger device than any of the FiiO's, and yet the BTR5 in my opinion sounds cleaner and also somehow can push up to virtually the same high output levels as the xDuoo, all without sounding muddy or underpowered.Seriously, if you're looking at other options that are bigger and heavier than you think you would actually like, don't sleep on the BTR5, the hype is real, this thing sounds so good, and has so much power, I find myself using none of my other BT receivers anymore. The balance of size, features, and performance in this thing is about as ideal as I could imagine it ever being. Do I still find myself wishing it had more battery life? Sure, but that's an unavoidable aspect of something like a BT receiver. I use this thing literally all day long sometimes, and when it is getting low, I can just plug it in to any USB-C charger, whether that's a phone charger plugged into a wall socket, or a battery bank, and it seamlessly will continue to crank out the audio without any downtime whatsoever. Thankfully, as with the BTR3's, the BTR5 doesn't have to reboot itself or anything when you plug it into power, so you really can use it for any arbitrary stretch of hours or days, as long as you're able to plug it into power for something like 30-60 mins, 2-3 times per day.All of this is great, but to me, the most impressive thing about the BTR5 really is the massive output power and truly excellent and clear audio you get out of it. As I mentioned above, with the BTR3, I typically wasn't using it with my M1060's, as it just kinda felt underpowered and not ideal.This is not the case with the BTR5, for multiple hours each day I have been driving my M1060's with this little BT receiver, and it really is shockingly close to the wired experience in terms of the audio. My desktop setup is a DAART Canary ESS9018K2M XMOS DSD DAC fed via S/PDIF, line out feeding a Syba Sonic SD-DAC63106, pre amp out of that ultimately feeding a Micca Bluetooth transmitter, which is what my BTR5 connects to.All that being said, let me just say, being able to adjust the audio levels of my M1060's via the analog knobs on my Syba amp without being tethered to my desk is just one of those things you'll probably only find satisfying if you're really really into your audio gear, but for me, as a pragmatic and obsessive audio indulger, it's one of those experiences that never truly felt complete until I got the BTR5 as the final link in my audio chain.TLDR:I love this thing, and will instantly buy another one if I ever lose it, highly recommended!

UPDATE: 2y4mo the glass is showing age. Electronically it still is my goto daily audio option. Ive gone thru about 5 sets of cheap KZ IEMs but the FIIO amp keeps going!!!Excellent product.1 year update: I work heavy industry, which means heat, rain, cold, mud, snow, more mud, dust, even more mud. I need my Bluetooth headset to preform. I also hate tin, thin, crappy sounding audio. Whether listening to streaming news via Sirius, Podcasts, Apple Music or FLAC files I personally ripped from some of the best 1st vinyl pressing of classic rock albums, I want excellent sound quality. After using LG for years, then many of those neckband clones, I got sick of tearing one earbud off it’s wire with no easy repair path. I learned of the ChiFi products with replaceable wires. Ordered some Cheap KZ wired buds for less than 30$, then got the BTR5 as the BT and alp to power them. Wow, and Wow again, this is an amazing way to do this. With the expensive part now tucked safely in shirt pocket the cheap parts are now only exposed to element, mainly mud and rain. I’ve pulled buds off the removable wires only to be plugged back in WO/ problem. The BTR5 give me easily 10hour shift of loud, fully dynamic music/talk with fail, BT doesn’t drop on either my old S8+ and now the Iphone11. Also used as a pure DAC when plugged into PC with USB to Type C wire, or wireless via BT with my Laptops(both Mac and Win10.) One time, repeat Once it would not work properly, their website side do a hardware reset by holding power button for 10 seconds, worked fine. Seemingly no loss of amp hours after a year. Face has gotten some scratches but no cracks, chips etc. wish there was a glass screen protector for this. Otherwise it was been flawless and if you can still get one Go For It. In the end cheaper than buy a 40-50 neckband style BT headset every 9 months.
