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 Brinson Quarterman

These adapters offer great sound quality, they're comfortable and offer decent noise cancellation. However, the adapters are so bizarre in their functionality that a rating above 2 stars would do Fiio and the people looking at it a disservice. Problems I often run into is that they don't always charge when in a suitcase. They randomly turn on in the case and drain the battery. The automatic shutdown function when putting it back in the case is unreliable. I have to turn on one headset before the other or it strangely connects to my phone. Lots of curiosities. I'm used to them but they're annoying and I wouldn't buy them again or recommend them to anyone who wants something that just works.
