Sennheiser CX 300S Reviews

Can't go wrong with Sennheiser

Sennheiser makes great products. Definitely worth the purchase.

Disappointed

Sounds great. However, when engaging someone on the phone, they have difficulty hearing me if at all.

Great wired headphones

I already had a pair of wireless earbuds but there are situations where wired is better for remote work. The Sennheiser CX300S provides a mic if I need it instead of my larger external microphone. Using it for remote work on my computer, it provides clear consistent sound for my needs.

Poor sound quality

Bought this to replace an old CX300 headphone that has been discontinued. Sound quality is night and day. This one sounds similar to a $5 cheap earbuds from the dollar store. Very deceiving for Sennheiser to use similar model name to push a low end product milking their brand name
