The B&O Beoplay E4 headphones are really a great product. Not only do they look pretty good, but they’re generally comfortable and sound great too. They’re not for purists, to be sure — the scooped sound wouldn’t necessarily be described as accurate, no matter how you look at it. But for those looking for a good listening experience, a portable form-factor, and noise cancellation, these are a great option.

The BeoPlay E4 in-ear headphones sound great and have admirable noise-cancellation abilities, but the overall weight of the wired remote and control box makes it a less comfortable package than it should be.
