Major malfunction issue with all PMX Headphones,
Verified Purchase(What is this?)
This review is from: Sennheiser PMX 685i Sports In-Ear Neckband Headphones (Electronics)
Initially loved these headphones, great sound , very comfortable & good controllability. Unfortunately I found with these & other Sennheiser headphones after a short period of usage about 1 month in all cases they all developed a serious control & intermittent sound issue. The 1st pair I ordered from Amazon developed an intermittent sound problem in the left headphone & the controls stopped working. I had these replaced & the same thing happened again after 4 weeks usage with the replacement pair. As a result I received a refund . It's a shame that a company as big as Sennheiser & adidas have released a product with a serious design issue. I'm not alone with this problem having read other reviews & issues concerning these headphones. The same problem occurred with some PMX 680i headphones I purchased as well. These are not water or sweat resistant as stated as I believe this is the reason for appearance of major faults on these headphones. Purchase these at your peril & ensure you keep the packaging as you will need to return these within the 24 month manufacturers warranty. I hope this review helps save a lot of disappointment .
