If you prioritize wireless connectivity and active noise cancelling for environments like air travel, the JBL Tune 660NC headphones would be the better choice as they offer both, enabling you to enjoy music without cable constraints and with reduced background noise. However, if you prefer a more portable and less conspicuous option that might be less expensive, the Sennheiser CX300S earbuds could suit you better, especially since they have good sound quality and are optimized for listening to music and TV. On the downside, the CX300S lack wireless capabilities and noise cancelling. Additionally, for those considering durability and making calls, JBL's headset offers an integrated microphone and is rated very good in build quality, whereas the Sennheiser's microphone and build quality are rated lower.

"The JBL Tune 660NC is the best value you can get from a set of on-ear headphones. There's no companion app so you don't get many additional features, but everything the JBL Tune 660NC sets out to do, it does well. At this price, the JBL Tune 660NC is an easy recommendation for on-ear headphone lovers"

"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."
