My Take: 8.5/10 However, I'd give the Sennheiser MM450 Travel a 10/10 for functionality. You won't find another pair of bluetooth headphones that does more.

- High quality material. - Comfortable, they are not too small and sit over the ears. - You can fold them. - 8/10 sound. - You can take your calls, control volume, and skip/pause music easily. - Somewhat short battery life. (around 7 hours) - Noise cancelling is nothing to write home about.

Had them here for about 8 months now, and they're absolutely gorgeous, before I had the Nokia bh something for 500 bucks, and it's such a big difference. Haft dom här i ungefär 8 månader nu, och dom är helt underbara, förut hade jag Nokias bh nånting för 500 spänn, och det är så stor skillnad.

I have used MX400 before I got these, and unlike the very bumpy and somewhat overpowered bass, the bass is much towards the natural side. If you are expecting very loud bass, MX450 isn't what you are looking for. I recommend Sony's e888 or AKG's k14p for strong bass response.

Making ( Durrrrr) Noise in Apple Ipod Touch Full sound -Am I received the faulty product ? i dont know but i returned back. EvenSennheiser MM 400-X is doing very good job.

They are great lightweight and comfortable for traveling. They do everything I wanted them for Music and phone. Bluetooth is great not having a wire to get tied up with, but wire can still be used when battery goes dead.

The awesomely portable MM 450-X cans might be the only pair of headphones you ever need
