If you're willing to invest more for superior overall sound quality and best-in-class build, the Bang and Olufsen Beoplay EX earbuds would suit you, especially for activities like exercising and air travel, as they feature sweat and dust resistance, active noise cancelling, and a longer battery life. These also support wireless charging and high-quality Bluetooth codecs for better wireless audio. However, if budget is a concern and you prefer wired listening, the Sennheiser CX300S earbuds are much less expensive and still offer good sound quality and comfort, suitable for casual music listening and watching TV. They lack the advanced features like active noise cancelling and aren't designed for exercise, but they are straightforward and easy to use without the need to charge them. 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 offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
