in april, my parents got me this with an iphone 16e. its good, had the bass, and other things i like. noise cancellation is good. later on, yesterday, my left ear started making noises. stopping this, i have to hit it a few times to stop. build quality could be a bit better, but i aint complanin.

This is the first ever pair of noise cancelling headphones I've owned. First thing that amazes me is the battery life. I went almost 3 weeks without having to charge these headphones. The app has equalizers so you can customize the sound. These headphones are very comfortable as well.

Never had noise canceling headphones. WHat a treat. I fly often and the headphones quiet the outside noise so I can actually sleep on the plan. Playing a movie or music on the plane is awesome you actually can hear the diolog or music with out the outside noise. The price was great.

Maybe these deserve a better rating. If volume isn't an issue for you, these are really nice. As others have noted, they are tight, but super comfortable. Have good range. Easy to use out of the box. But they are just not loud enough. Nothing I could do with the EQ made it any better.

Bought two weeks ago. After charging it with the given connector overnight (approximately 8 hours), the u stayed on for about 45 minutes, and promptly went off. Subsequent connections to the left side port did not show an orange light, or any light at all when plugged in.

Love the headphones but if you want super loud music this isn’t it. They do get loud but if you’re working out pretty intense you can hear some distortion for sure. I would buy again tho. One thing I don’t like is when I move one side off the ear to hear my gym partner that it pauses the music.

I bought customized 660 headphones a few weeks ago. Really enjoyed. Top tier. I bought the customized version after losing my other pair. My only complaint is the design didn't come out quite as I wanted. But still I'm very happy with them.

I needed a pair of over ear headphones to wear at work. I work in a loud environment and noise cancelling headphones or earplugs are a must. I was having issues using earplugs everyday, shoving earwax deeper into my ears. I can't find noise cancelling earbuds that fit well so I gave these a try.

The headphones seem to be working well so far. But, the personalization is very shoddily done. It looks like a child's rub-on tattoo. I would NOT recommend getting any sort of personalization. I regret that we did.

They fit all sizes of heads. The battery life is excellent, which means you only have to charge them once every week. The portability is top tier. The weight of the headphones are very light so they are easy to carry around. The noise cancellation is very brilliant and constant.
