Nice Sound. Poor Durability,
This review is from: Sennheiser PMX 685i Sports In-Ear Neckband Headphones (Electronics)
After previously owning a bright orange pair of Sennheiser "sport" headphones that had unfortunately stopped working due to rust in the ear buds I decided to give them another shot with the Sennheiser PMX 685i headphones.
Soundwise I was impressed and (unlike some reviews) I found them to be very comfortable to wear, even over 15+ mile runs. On this alone I'd have given them 5 stars.
However, within two months they developed a fault where the volume control no longer works although play/pause still does--very annoying. Given the number of other reviews with similar control issues, you have to say the build quality of this Sennheiser kit is very poor. My experience isn't an isolated incident. It's not like they're the cheapest of headphones either.
On a less important, but equally irritating note, the little blue rubber pieces that go around each ear-bud (I guess for comfort) slip off with amazing ease and regularity. On several occasions I've found them on the path outside my house or on the floor somewhere inside. Again, poor build/design. Take care or they will get lost.
Sorry to say but I really think I've purchased my last pair of Sennheiser headphones.
