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 Tamara Palmer

Probably the most difficult device I have ever owned. The red and white center for the draw never happened. You will see that the white LED will light up for just 5 seconds after opening the case and that's it. Connecting to my phone to update the firmware never went through. I wait 10 minutes for the reboot. Canceled and trying to update the right side, no don't want to update. The app looks promising, except that you can't change anything. For example, the equalizer looks like you can change the setting, but it's just an image. You can't customize anything at all. He comes back.
