Only had my ear buds for a few weeks and have used them a handful of times. So far I’m not too happy with my purchase, they keep rebooting and making a thumbing noise. I am going to continue to use and hopefully these issues will go away

The left earbuds has a squealing sound like mosquito sound and it cannot be heard while listening to audio but I also use it while reading and it's irritating. Chose this for comfort instead of Sony

Thanks for your review! It's good to hear you're enjoying the noise cancelling of the QuietComfort Ultra Earbuds. If power-cycling the product doesn't help with the sound in the left earbud, then the sound would appear to be normal. A certain "noise floor" will exist in all earbuds with active electronics, but it should only be heard in quiet environments, with music off and noise cancelling set to high.
This are the pair that louse all day and loved them the punch bass and the noise cancellation, comfort fitting in my ears is the best totally recommend to everyone!
