First of all i wanna point out that they haven't got any issue like only one handset connecting and the other one not working . They are a good fit , never had issues listening for long time and the best part is that they last more than it is advertised . Now , a little pros and cons :
+ Great price tag / Paint doesn't chips away / having extremly sound drivers perfectly for listening to bass and treble
- They need some improvement though like a better sound driver because the sound is like stuffed and too low when speaking on the phone either via callss or social media calling services
