For the price, these are excellent earphones. I don't think you can get better value for money at this stage. That said, I can't help but compare them to the more expensive earphones I'm using them to replace.
At first, I had issues with bass drones overpowering higher tones to the point where some sounds were lost almost entirely, but this issue was mostly mitigated by just swapping out the foam caps for others (you actually get a generous assortment of replacement caps included, although mine mistakenly has three large caps and one medium instead of even pairs).
The sound still isn't as clear as I would like, but it manages a lot better than similar alternatives. The noise-cancelling options are also pretty impressive whenever it's needed, despite the clarity taking a bit of a hit in my experience. It's not really for me, but having options there is very appreciated.
The overall build and comfort is generally pretty good, too. They feel a lot more durable than my previous earphones at several times the cost, and the magnetic tips are a great touch. My only complaint is the inline volume slider; it works, and I'm glad to have inline controls, but it's very touchy at the high end to the point of being unwieldy, especially on the move. Physical volume buttons would make it control more consistently, but it may just be a matter of preference.
All up, if you need to replace a damaged pair of earphones, I would highly recommend these. None of my issues are deal-breakers, and there's plenty of nice touches to make up for them. Unless something goes horribly wrong, they're going to be my daily choice for quite a while.
