FiiO UTWS5 2025 True Wireless Bluetooth Earbuds Hook & Headphone Amp for IEMs, AK4332 DAC, Hi-Res 96kHz/24bit LDAC -MMCX/0.78 2pins Connector, 10-Band PEQ, 20H Battery Life (MMCX)

Sadly the left hook only works for 2 minutes when you remove it from the case. Then it drops from 100% to 1% battery and dies after a further few minutes. Comfort and sound wise they are amazing though. I contacted fiio customer service since Amazon didn't want to know, they answers quickly at first but then nothing for weeks. So I returned these for a full refund and will buy another brand.

Arrived with the left ear hook charged and the right totally dead. Tried several times to charge the right ear hook but wouldn’t go above 10%. Poor quality is not acceptable at this price.

As a long time user UTWS3 adapters, I’ve been patiently waiting for FiiO to release a new version of these adapters that solves the charging problems. For some reason, FiiO seems to be the only company who has figured out how to make true wireless adapters that work well and have flawless sound quality. The only issue has been the charging connections being unreliable. But with these new UTWS5 adapters, they have finally created the perfect true wireless adapters for IEMs. The charging system works flawlessly as opposed to the janky UTWS3 that made you jiggle the case until the connectors lined up, and the sound quality is as good as it gets. There is absolutely no hissing noise, and these sound identical to a quality IEM cable. The Bluetooth connectivity is also super fast and reliable. The battery life is solid and the charging time is lightning fast. They are fairly comfortable, and I can even wear them comfortably under my motorcycle helmet and still slide a finger in to press the button to skip songs. I use these with 7Hertz Timeless AE IEMs and the sound quality demolishes AirPod pros or any other system I’ve tried, including over the head headphones. I will probably use this setup for the rest of my life as I genuinely cannot fathom how something else could sound better, and these don’t have any of the Bluetooth/battery/comfort annoyances of literally every other true wireless adapters. Edit: now that I’ve had more time with them, there is one huge frustration. Once every couple weeks or so, the left and right hooks refuse to pair with each other and you only get sound from one of them. This is fixed by holding down the hook buttons on them for 10 seconds until they both say “power on” twice. Then you wait for them to pair, which can take up to 5-10 minutes. Very frustrating that they do this when the previous versions do not. They still sound great and this should be fixable with a firmware update, but they’ve been doing this ever since I bought them.

Duró poco, con la actualización,,sólo está en CHINO…

Work as intended.

Very disappointing battery life, stays about three hours of continuous usage. Otherwise the performance is good like i wanted but the battery ruins it

Ive been through 3 iterations of these - the UTWS3, UTWS5, and the UTWS5 2025, and all three had their problems: UTWS3: had such a convoluted and near useless pairing protocol that I just gave up on them. I currently use this set for listening to music from the one device I did manage to pair to. The mikes are pure garbage and I couldnt tell you about how long they last because I rarely use them even so. UTWS5: these paired and sounded great until one side stopped charging. The charging contacts were oxidized so I cleaned them up with contact cleaner but it was hit or miss with the charging thereafter. Then they developed crackling sounds and sporatic sound drops, so I bought the... UTWS5 2025: sound great, wireless charging inside the case so no contacts to oxidize, and no problems pairing, but within a few months now after purchase the left side has momentary sound drops. I love their sound, I love their battery life, but the quality falls far below their price point. After 3 different models with the same eventual result of just going bad prematurely, my next purchase for this form of bluetooth will be the Shure TW-2. The FiiO UTWSx will go bad on you, it's just a matter of how soon.
