Summary: I use them continuously: during the commuting in the subway, on the plane, at home and in the office for my conference calls.
I was expecting much lower musical quality from a BT can, but actually I had to change my mind: those headphones are remarkably good.
Pros: Work as a headphones even without batteries, very comfortable, light weight, very good built , good sound
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! Good sound considering they are wireless. Very well built and look like they will be very durable over the long haul. Very comfortable. Noise cancellation is great for eliminat...
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. My iPod was upstairs and I was downstairs listening to music without any interruption in the sound quality.
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. The noise reduction feature doesn't muffle the sound quality. These are comfortable headphones for long-play audio. I took the advice of a fellow user and bought a backup battery so I'm never without stereo music.
Pros: Terrific sound quality, truly portable, comfortable for long periods of time.
Excerpt: I am not an audiophile but I would rate the sound as very good to excellent. The sound experience seems to have more to do with how well balanced the recording is than with the headphones themselves. Sometimes the bass is a little lacking on some recordings but is much more than adequate on others.
Excerpt: I am an international frequent flier and the airline headsets can be really nasty. I wanted something that was portable, wireless,had good noise cancelling technology and great sound. I opted for on-ear as buds too uncomfortable and over-ear made them less compact. I pack a lot of gear (iPad, PC, iPhone, adaptors for 4 countries, so wanted something that would fold up and safely and compactly fit into my biefcase.
Pros: Alternate between music a, Bluetooth pairing, Clear Sound, Durable, Easy Controls, Lightweight, Long battery life, Versatile
Conclusion: Kjøpte dette for å bruke ved kollektivreiser til og fra jobb. Støyreduksjonen fungerer bra, og stenger ute det meste av bussdur og togsus. Det kunne dog lukket ute mer av høye frekvensområder som skranglelyder og snakking. Lydkvaliteten er det ingen ting å si på, det er ekte "sennheiser-lyd" og låter som andre sennheisere jeg har prøvd. Godt detaljrikt lydbilde og fyldig bass som ikke blir påtrengende. Prisen er stiv, men jeg angrer ikke på kjøpet.
