If you value wireless convenience and portability for use during travel and exercise, along with superior build, sound quality, active noise cancelling, and sweatproof features, consider the Bang and Olufsen Beoplay EX, but note they are at a premium price. Conversely, if you seek good overall sound quality and comfort at a budget price, and don't mind a wired connection or lack of noise cancelling, the Sennheiser HD 400S headphones would be a suitable choice. The Sennheiser are over-ear and may be better for long listening sessions, but they aren't as portable or workout-friendly as the earbuds. Give Feedback

"If you’ve wanted truly wireless headphones, but couldn’t pick them up because they sound terrible, these will be the headphones that win you over. If you’re the kind of person who would consider spending $400 on headphones, these are the right truly wireless headphones for you."

"Sennheiser has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you."
