Review on 🎧 FiiO UTWS3 Bluetooth V5.0 aptX/TWS + Earbuds Hook MMCX Connector with Mic Support - Enhancing the Listening Experience for Shure SE215 SE315 SE846 SE535 SE425/JVC/FiiO FD5 FH7 with 30 Hours Playback and APP Control by Heidi Massine

I would give 5 stars but the pairing never worked the way Fiio intended. I tried to pair by pressing the multifunction button for 3 seconds and it doesn't turn red and white as shown in the video to indicate pairing. As a result, I had to make each earbud separately. Constant problems with Bluetooth "connected, disconnected, connected, disconnected, connected, disconnected, connected, disconnected, connected, disconnected, connected, disconnected" THE CYCLE NEVER COMPLETES AND NEVER TRANSMITS AUDIO! Has anyone actually used these things before putting them on the market? [Edit 2]: 2 months later. The charging case will no longer charge adapters until they are full when the case is unplugged, even if the case LED shows that the battery level in the case is good. [Edit 3]: 6 months later. Now they are completely dead, connecting to nothing, not updating from FiiO app, getting no sound, nothing. This company gets high marks and I ask WHY? This is an absolute joke, $80 down the toilet. Also, adapters CONSTANTLY lose connection when playing and pausing videos rapidly. This is a big problem when you need to edit videos and play/pause to censor words, or when you're watching a movie and want to rewind 10 seconds. FiiO said they can charge the adapters up to 5 times, I can't even get a full charge.
