Okay, so I've had these E7 noise-canceling headphones for almost a year now, and here's the tea: they're actually pretty solid for the price!
First off, the battery life is insane - like 30 hours? I only charge them once a week even with daily use. The sound quality surprised me too. The bass hits nice and deep without drowning out other frequencies.
The noise cancellation works well enough for my commute. It blocks out airplane hum and subway noises decently, though don't expect complete silence if someone's yelling nearby.
Comfort-wise, they're cozy but do get warm after a few hours. As someone with smaller ears, they fit me perfectly though I can see how big-eared folks might struggle.
Now for the quirks: that annoying voice that says 'power on' every time? Yeah, wish I could mute that. And there's this tiny blue light that never turns off - had to put tape over it for nighttime use.
The mic quality is... well, let's just say stick to calls in quiet places. But hey, at this price point you can't expect studio-level quality.
Funny story - my first pair lasted THREE YEARS even though I accidentally showered with them regularly (don't ask). That alone tells you about their durability!
All in all? 8/10 would recommend if you want decent ANC headphones without breaking the bank. Just maybe keep them away from water unless you're testing their limits like me!
