Excerpt: I bought these because I travel a lot for work. I was excited when I got these and took them on my trip to Orlando - put it to use with a flight full of kids. The noise cancelling worked well and bluetooth was solid. On the flight back however - different story.
Excerpt: I do a fair amount of traveling, and also listen to classical music frequently through headphones. For several years I have used Sennheiser PXC300s which provide excellent sound, but I was looking for 'phones with better noise cancellation.
Pros: Comfortable, Compact, Excellent noise cancellat, Great Sound, Lightweight
Excerpt: the sennhieser mm450x has a very clean and clear voice of song details but you feel at a moment that you need more volume while you reialize that this is the maximum. .. anyway if you think about it from health point of view.. the very loaud headphones might heart your ears ..
Pros: Attractive Design, Bluetooth, Durable, Easy To Assemble
Summary: None, I got these instead of the MM 550X because I prefer something smaller that doesn't encapsulate my entire ear. They are very light, fit very well, and they are not bulky at all.
Pros: This product has made me much more productive at work. I paired my business ShoreTel VOIP phone, iPhone, and PC with it. Now, I only need these headphones to manage all three with a single button. Make me more productive by allowing me to keep my hands on my keyboard and my eyes on my monitors! G...
Cons: None so far, I'll report back if I encounter any. A little pricey on the surface but once you have it and start using it the price concern will quickly fade away.
Excerpt: I use the bluetooth headset to stream music from my TV and music system and the quality of the sound is great. Pairing was easy. Fit is tight (which is what I wanted), but not too tight. Looks good too. Love the accessories that are included. More than what the competitors provide.
Pros: Comfortable, Compact, Good Bass, Great Sound, Lightweight, Stylish
Excerpt: After reviewing many makes and models of headphones, the Sennheiser MM450 was the one I chose. I'm thrilled with my selection !! Perfectly compact for travel and versatile use for audio cable or bluetooth. Plus, they are Active Noise Cancelling. I was really impressed with the bluetooth range.
Pros: Clear Sound, Easy Controls, Lightweight, Top Quality, Versatile
Summary: These are my top choice of go anywhere headphones. I've found the ideal product for use with my mobile devices. These headphones have outstanding sound quality especially the bass. I enjoy the sound quality of all types of music - rock, jazz, and classical.
Pros: Terrific sound quality, truly portable, comfortable for long periods of time.
Excerpt: Great sound and easy on the ears. Furthermore, great on a plane with screeming kids, noise canceling works as stated. ActivX is a plus. Rather pricey and a little finger practice with the controls.
