If you prioritize a premium gaming experience with excellent sound quality, microphone clarity, and an expansive soundstage, the EPOS PC38X will serve you well. However, for a lower-priced option that offers a more versatile, portable experience with active noise cancelling for better isolation, and longer battery life for on-the-go listening, the Sennheiser 450BT would be suitable. Keep in mind that while the EPOS excels for gaming due to low latency, it lacks wireless capabilities and is not optimized for exercise or air travel, whereas the Sennheiser provides those conveniences along with foldability for ease of transport.

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
