Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I've tried out a couple, they're usually overpriced for what they are (average to mediocre IEM that would sell for $10-40 + BT functionality that shouldn't cost more than $40)...
I'd rather use my regular high-quality IEM w/a Bluetooth receiver. Yeah you don't get rid of wires entirely going that route, but my biggest goal is just freeing up my phone/player so I can handle it w/o wires bouncing everywhere; plus when the receiver runs out of charge you can just plug the headphones into the player directly... There's other advantages too, like longer battery life, easier to handle controls, etc.
Most BT IEM/headphones are worthless once the battery's drained (there's some exceptions). Sony MW600's a good receiver IMO:
