If you prioritize excellent overall sound quality and use your headphones primarily for music, calls, and gaming, the EPOS PC38X would be an excellent choice, particularly with its superior microphone quality. However, keep in mind that they are open-back headphones which means they don't isolate noise well, making them unsuitable for noisy environments or air travel. On the other hand, the JBL Tune 660NC has active noise cancelling and is more affordable, making it better suited for commuting or use in loud places. It's worth noting that the JBL has lower sound quality and mic performance, but offers portability with a foldable design and longer battery life for wireless use. If you often partake in activities where noise cancellation and wireless capabilities are valued over top-tier sound, the JBL could be the more pragmatic choice. Give Feedback

"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"
