After a quick check with my big HiFi headphones (usually on the stereo system in operation) it was clear that the iPod to significantly longer was capable of.
New headphones were needed.
The CX300 spoke to me for several reasons. Firstly, I have great confidence in the brand Sennheiser and know they are at that. The in-ear system also appealed to me for a long time, because I do normal earphones to time hurt.
I was not disappointed. The sound is a world away from the original parts. The bass is punchy, dynamic noticeably better. Just a balanced sound. The volume is increased significantly, so I had to make the first iPod quieter.
The in-ear system is super. The plug disappears almost completely in the ear and seals this off. There penetrate much less ambient noise inside and it lost less sound.
Sennheiser puts the plugs for the rubber parts in 3 different sizes, so that the CX 300 should actually fit inside each ear.
This purchase has more than paid off. Also priced one remains in the frame. Who values quality and just want to get more out of his MP3 player (or other devices), which is served right here.
