Review on Sennheiser CX 300S In-Ear Headphone with Smart Remote - Black (One-Button Control) by Hideo Masuda ᠌

Decided to take more expensive and newer. I thought that the sound quality would be higher than that of the cx 300ii, but this is far from the case. Before listening, I let them warm up for an hour, just played at 60% volume, I thought the sound would change after. Nothing has changed as it was and remained after the first start immediately felt the difference. It's a pity they don't release cx 400 there are very cool double ear pads. And the sound in 400 is very balanced there was just enough. In general, I gave new ones to a friend and took cx 300ii from him, although they were worn. And a friend also said that the sound is better on the old cx 300ii.
