Customer Reviews

The sound is very good - but why the split cable?
After suffering with inferior quality earphones for a few months after my cx300s died I had to go for sennheiser again for the great sound quality - and these looked ideal because they provide the all important shirt-clip. My main use is whilst running and I want good sound with lightweight earphones that are secure and cannot bounce out of my ears.

The new lead design is horrible. A far-too short lead with an extra meter of lead that attaches by a weighty connection. Basically, because of the extra weight if you want to run they bang around uncomfortably knocking all over the place. Also the leads fly up and whack you in the face making these some of the most annoying earphones I've had.

After elaborate experimentation I've made them more or less secure involving tucking the connector-weight inside my shirt and using an extra clip from old earphones to fasten the round the back - they would have been absolutely perfect with just 1 longer lead and a decent fastening clip.

Great phones
I was quite sceptical about in ear bud type 'phones, but these CX400 'phones are great. A bit strange when you first wear them, but they fit really well and block almost all outside noise out without needing the volume high at all.

Stick with the CX 300 instead
Just purchased these headphones and I must say I am very disappointed. Having previously owned the CX 300, the cable split so I decided to try these.

The CX 400 cable has been shortened to the extent that it is unusable with anything that will sit in your pocket without using the supplied extension lead. The sound was also disappointing compared to the CX 300. I've just tried both pairs and the CX 300 had a much nicer bass, cable was perfect length and the "behind the head" cable design was more comfortable.

I love Sennheiser headphones and have owned several pairs over the years, from outer ear to these and I've even owned some Shure EC3 headphones. My favourite for comfort, value and usability is the CX 300 so stick to these and you won't be disappointed. All the positive things you hear in other reviews about the quality of these is true, but better in the 300 (and cheaper). I'm going to tape up my old ones and use those instead.
