FiiOUTWS5 Bluetooth Amplifier Earbuds Hook 96kHz/24bit Hi-Res Wireless Bluetooth 5.2 30hrs Battery Life IPX4 0.78mm 2pins

--- Long-Term Use Update ---I installed the new v1.71 firmware today (which includes LDAC support!) and wondered how long I've owned these. Since I came here to find the answer anyway (18 months), I'll take a moment to update on their reliability.After all this time, my UTWS5 are still working perfectly, without the frequently-reported charging issues and no problems with them connecting randomly when they're in their charging case. Connection quality during use remains stellar. In the event that the aforementioned issues are user-induced, I'll note that I make it a point to ALWAYS wipe the earhooks clean (particularly around the charging contacts) before returning them to their charging case; this may or may not have contributed to my ongoing positive experience.LDAC has been rock-solid during today's listening session in my home office, with no audio stutters or connection drops even when moving around the room with the player on my desk. One session is hardly adequate for a definitive assessment, but it's promising so far.So, after 18 months of ownership, the UTWS5 are, for me, a five-star product that I'm still happy to recommend.--- Original Review ---I own two Bluetooth MMCX cables: an eight-year-old Sony MUC-M1BT1 and a six-year-old Westone BT v1 cable. They both still work perfectly, but I looked to the FiiO UTWS5 to add true wireless convenience, longer battery life, and a newer Bluetooth standard/codecs to my MMCX IEMs.I tested the FiiO UTWS5 with Westone W40, Sony XBA-H3, and 7hz Timeless. With all of these, the UTWS5 easily outperformed both aforementioned Bluetooth cables in sound quality and longevity. I'll leave the lengthy and nuanced sound analyses to the audiophiles.For IEMs with traditionally-located attachment points such as the W40 and Timeless, the UTWS5 ear hooks fit perfectly and comfortably. However, please note that if you have odd-shaped IEMs such as the Sony XBA-H3, they fall beyond the adjustment range of the UTWS5 ear hooks, and it is not possible to hang them behind your ears. You can still use them, if you like the idea of the ear hooks floating next to your ears instead of hanging behind them (I don't recommend doing so in public).Despite having countless other in-ear, on-ear, over-ear, wired and wireless options around, the UTWS5/Timeless combination is quite enjoyable to listen to and I find myself using it often.Regarding hardware and software, I have not experienced any of the issues listed by some reviewers. The ear hooks charge like they're supposed to, and they do not randomly reconnect to my devices (so long as the battery in the charging case isn't depleted). Phone call quality is good. I use the FiiO Control app only to update firmware as updates are released. I do not use the ambient pass-thru mode, and I don't care about custom button mappings. For my needs, the FiiO UTWS5 are great and I highly recommend them.

Sound quality is great. Won’t go into details.Tip: ambient mode can be triggered by 3x taps on right ear. Same on left activates assistant. This is not mentioned in app or help guide but on their blog post for firmware release.Fit: It’s light, but a bit bulky and can hurt ears over time.App: terrible. It works, but it’s glitchy and slow. Thankfully you can avoid it completely once set up.Operation and lid annoyance.The box has to close completely or the headphones will be connecting to the device again. Close the lid and they go to sleep.This is nice in theory but causes issues.If the fit isn’t perfect and it can’t close - it’s gonna be trying to connect to your device and stay on even if inside the box.If the lid opens in a bag, or in any other scenario - it will turn them on.If you are using an adapter, get the L shaped one. They won’t fit inside the box otherwise and all the lid madness will ensue.That’s very, very annoying, as the lid isn’t the best at closing firmly and staying closed. Problem can be resolved by a rubber band but it’s annoying. Did I say it’s annoying?To Fiio:Please fix the lid issue. Only turn on headphones when taken out of the box - can be fixed in firmware. The lid needs to be firmer or locking too.If you can provide adapters or sell adapters it would also be great. I needed an MMCX to IPX to make it work. Would be great if I could buy it from you.

So I am listening to Purple rain right now using the UTWS5 connected to my Vivo X200 Ultra and playing music through my Unique Melody Mest IEMs. I wish I could have written this review sooner, but I've been busy listening to music instead ofr 3 weeks straight, seriously. I've used this combo to relisten and rediscover music I've listened to before and now discovering new music. I can say a lot of technical things, but none of that matters. The UTWS5 got me to enjoy music again. It made my favorite pair of IEMs into a wireless wonder.Two things to note. The sound is damn good, not as good as wired, but darn close and I can walk like 70-100 feet away clear to the other side of my house from the phone and still hear music clearly. Battery with the Mest is lasting 6-7 hours on a full charge. The buttons are intuitive to control music. I simply love what the UWTS5s have done for me. Oh yeah and the EQ from fiio app is darn good. It pushes the hell out of my IEMs, never heard so much bass out of my Mests, they are like bass cannons now with insane highs. Thank you UWTS5... eerr FIIO.
