Boost your sound with Sennheiser's CX 300S earphones which offer amazingly detailed sound reproduction and enhanced bass response thanks to Sennheiser's transducer technology.
Never received à this day :) UPS sucks
It's the third pair of Sennheiser headphones I buy, one for me and 2 for my kids and we all love them. I personnally own the older CX 5.00G, while my kids have the CX 300S. Build quality, sound and comfortability are amazing. The only drawback is that the cords carry noise to the headphones while walking, so maybe not the best sports heaphones.
Sennheiser sound signature and clarity is great. Bass is a bit muddy but maybe it’s the product blemish i guess? But overall good for music and office work.
everything fine; i only miss a practical earhook to this In-Ear-headset
