If you prioritize gaming, calls, or music with a wide soundstage, the EPOS PC38X offers exceptional performance with a best-in-class microphone for clear communication. They're designed for long sessions with comfort in mind but are not made for exercise, as they provide poor isolation and aren't sweatproof. Conversely, the Sennheiser Momentum Sport earbuds are tailored for active use, featuring sweat and dust resistance, with added health tracking functionalities. They also support AptX Adaptive for better wireless audio quality, active noise cancelling for quieter environments, and are more portable, but they come at a premium price. Make your choice based on whether your use is more stationary and gaming-focused with EPOS or active and feature-rich with Sennheiser. Give Feedback

"Lightweight and comfortable design, Mic arm with mute, Excellent tuning, Highly natural midrange voicing, Clean and separated bass, Solid soundstage dimensions. Combining all day comfort and integrated coms with a balanced and spacious sound from essentially any source, it is hard to deny the versatility and value provided by the PC38X."

Amelia Schwanke | January 2024
"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
