Had these for about 7 months now. They have been good overall. After about 6 months the battery starts to die much sooner and recently have had issues charging even with the original USB cable being in good shape and little wear on the headphones. Paint scratches easily. From the start, the bass on these are lacking, especially if you listen to newer hip hop. As for the Google Assistant feature, it gets buggy sometimes and requires good signal connection and sometimes it is hard to connect to your phone. I love the feature when it is working properly. Maybe future models will have more customization options for the feature.

[This review was collected as part of a promotion.] If you're a big dude like me you'll find comfort in knowing that these headphones will fit your head perfect I've never found a pair of headphones that fit my head so comfortably not only are they comfortable they look good while you're wearing them the sound is amazing you can customize it anyway you like with the JBL app ....the noise-cancelling is perfect the JBL Everest Elite 750 NC is the real deal!!! You owe to yourself to to own a pair!

I've tried / purchased the top of line Bose and Sony NC headphones... Bose and Sony both had excellent acoustics but we're hollow on the low end. Construction was excellent or good /respectively. The JBL Everest Elite 750 NC are every bit the same. NC performance is as good but slightly different. Not worse or superior. Build ... Sony were slightly off but near 97% comparable. The JBLs fit well with perfect perimeter pressure and weight/bulk. Critically, JBL boasts tighter more powerful bass. I seem to FEEL more low end pressure well in excess of Bose or a distant Sony performance. In my profile of demand JBL wins easily with an edgy SQ, matching performance in build and acoustics combined with lower actual cost! Five stars easily! I might add I like the amplified mode ... However... We bought two sets and my daughter complianed one set has a faint humming in the background when sync'd on BT. I only heard it in silent transitions and judged it insignificant. So she uses the perfect set and I'm fine with the near impossible to hear humm with age 50+ ears. Final word... I've got a pair of iconic JBL 100 studio monitor (not true 4311 monitors) refurbished with factory original foam surrounds. So yeah... I'm partial to the JBL mix of acoustic character. Actually the Bose and Sony had unacceptable bass performance... JBLs were like the 3 bears with Goldilocks where the porridge was "just right"... Yeah... JBLs were perfect for acoustics!
