The sound quality is great on this--music and other audio sounds excellent and the volume is so much higher than the Plantronics headset I had. Ordered one size up and it fits well. Great shipping, great product. Vs el Logitech G305 era la gran pega. I ordered another pair of slippers for my other granddaughter in Medium. Ok look. Look and fit great on our 2 almost 3 year old daughter. This trash is going to be returned asap. I shelled out the bigger bucks for these after my LL Bean slippers finally gave up the ghost, beyond (my ability to) repair. With the adapter being so small, I dont have to worry about losing it.
