A pair of very affordable wireless over-ear headphones with active noise canceling, the Mixcder E8 will set you back a mere $70/€60, and if that's all you can spend on a pair of wireless headphones, there are many aspects in the Mixcder E8 to completely satisfy you.
First and foremost, for the money, the Mixcder E8 sounds quite good—not very detailed or wide-sounding, but with thick, boosted bass that makes up for a lot of that and delivers exactly what many average listeners want to hear. While artificially boosted, the bass is not completely overdone, which means this pair of headphones is by no means only suitable for fans of hip-hop and EDM—the Mixcder E8 holds its own in a number of other genres as well, including guitar-driven ones. However, the ANC feature is disappointing as it does not actively block anything except for very deep and constant frequencies. On the other hand, after going through over 30 ANC headphones this year alone, I can confidently tell you that you simply won't find a good ANC variant in the sub-$150 price category. The Mixcder E8 falls way below that, of course.
These headphones are also very comfortable during even longer listening sessions, and the rechargeable battery regularly offers around 15 hours of playback. The built-in pinhole microphone is very usable for wireless phone calls, although it's a shame that this functionality isn't available in wired mode as the manufacturer didn't equip the supplied audio cable with a secondary microphone (or a set of buttons for playback and volume control). The build quality isn't very convincing either, which is the biggest drawback as far as I'm concerned. I actively used them for about a month and didn't run into any integrity issues, but the fact remains that the cheapish plastic and creaky joints don't look or feel like they could take too much abuse. If you carry the Mixcder E8 around in a crammed backpack, do use the supplied hard-shell carrying case. With a bit of care, the Mixcder E8 should serve you well for years, which only makes the investment that much more worthwhile.
