If your primary focus is on sound quality and you prefer over-ear headphones, the Sennheiser HD 350BT offers excellent overall sound and is especially good for gaming and TV due to its low latency. However, if you need active noise canceling and value the option to use wired connectivity, the JBL Tune 660NC is a suitable choice, although its performance for gaming and TV is not as strong. The Sennheiser lacks active noise canceling but has better microphone quality, making it a solid choice for calls. Both offer app customization, but only the Sennheiser supports AptX Low Latency codec. If you travel frequently, consider the JBL for its foldable design and active noise cancellation, but for long listening sessions at home or during commutes, the Sennheiser's superior sound quality may provide a more immersive experience.

"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"

If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."
