Sennheiser CX 685

The Sennheiser CX 685 has received positive reviews for their awesome durability and for their decent sound quality. Users also like the noise-cancellation, suggesting they block out a lot of external noise, especially in noisy gyms. While this may not seem like an important point, the customer service is said to be excellent, with user pointing out they are quick to assist with any queries one might have. Some users did however find that there were some issues with sweat dislodging them from the ears. We hesitantly add this point however, as there were many opposing reviews where people found them to be a perfect fit for their ears. Users also found that although the overall sound quality was great, their bass was not as deep and full as they would have liked. All-in-all, the Sennheiser CX 685 in-ear sport’s headphones are built to last. They may not be ideal for activities that require a lot of movement, such as running related activities, but are perfect for busy gyms.
