Considering your options, if you prioritize wireless convenience for tasks like casual music listening or air travel, the JBL 510BT would be the right choice, thanks to its wireless capabilities and longer battery life. However, these headphones might not provide the best comfort for extended listening sessions. On the other hand, the Sennheiser CX300S, while costing a bit more and being wired, offers better sound quality and noise isolation, which could make them preferable if you're looking for earbuds to use in noisier environments or for focused listening to TV and videos. The CX300S are also lighter and more portable, making them a better pick for on-the-go use. Neither option is well-suited for gaming due to latency issues and for exercise because they lack sweatproof certification. Give Feedback

SoundGuys

Sam Smart | September 2023
"The JBL Tune 510BT is affordable and compact, making it a great companion for a commute, so long as you don't need active noise canceling. If you wear glasses or have ear piercings, the on-ear design might not be comfortable, since the ear cups will squish your ears."

Major HiFi

Carroll Moore | April 2019
"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."
