    I was in the market for a headset for my iphone 3gs to replace the ear bud ones that came with it. Those sound pretty bad. The Sennheiser MM-400 by contrast, sounds great. One of my pet peeves with cell phones is having to hold the thing up against the side of my face. That gets uncomfortable after a while. Since the iphone also includes a very nice ipod feature, I also wanted a headphone that will do full justice to my music. The Sennheiser mm-400 does all of that and does it very well.

    This Sennheiser produces top tier sound, and the stereo blue tooth works perfectly with my iphone. Sound quality is impressive and my high bit rate mp3 music files sound like real music…not the tinny sounding stuff that the standard Iphone ear buds produce. They are not an active noise cancelling headphone…for that you have to buy the next model up from sennheiser, the mm450. They do isolate you from external noise by their very design though. They are a closed back design and seal onto your ear to block out noise. I have worn them for hours at a time and they have never felt uncomfortable.

    The headphone has intuitive buttons on the right earcup for adjusting the volume up and down as well as changing audio tracks and turning the headset on and off. The changing tracks function does not work at this point with the iphone, but that is no fault of Sennheisers. Apple chose not to implement that particular control function in the iphone with their current bluetooth firmware. That could change in future releases. Being able to keep my iphone in my pocket while listening to music and still being able to adjust the volume is very handy. Being able to change tracks would be nice as well.

    Making or answering a call with the headset works great. If I’m listening to music and a call comes in, the iphone beeps and a touch to the main button on the headset stops the music and answers the call. Voice quality, both on my end and on the side of those who are talking to me is excellent. They have said they can’t tell I’m talking on a cell phone at all. The mic is built into one of the earcups and is not visible externally. It works though.

    The user replacable battery has a very long life. I have used the headphone for several days without it needing to be recharged. Recharging can be done through a USB port in a computer or through the included wall plug. You can also buy an extra battery from Sennheiser and swap out a depleted one for a freshly charged one if you will not have access to a charger for an extended period. The battery is rechargable outside of the headphone as well as while installed in the headphone.

    For occasions when you prefer to use a corded headphone, the sennheiser comes with a cable that allows you to do that, deactivating the bluetooth system. For example, on an airplane when you can’t use wireless devices, place your iphone in the airplane mode and use the wired headphone connection. That turns off the cell phone and blue tooth capabilities of the iphone and allows you to use it strictly as an ipod for audio and video.

    The MM-400 can synch with and remember up to 5 different devices. Once you have made the initial synch, just turning each device on within range will link them.

    Included in the box is a nice zippered travel pouch for carrying the headphone plus it’s charger/cables. The headphones fold compactly for travel and are robustly constructed with lots of metal construction that has a quality feel to it. That bodes well for long lasting durability.

  • Review by Robert O. Peruzzi "Mixed Signal Design/Verifi...

    I had been looking for a headset with these features for quite some time:
    * On-the-ear (as opposed to over the ear or in the ear)
    * Telephone compatible
    * Pretty good stereo audio

    That’s all I needed. On-the-ear so I can use it with hearing aids in place, and pretty good audio is good enough for my burnt out musician’s ears ;-( I use it to listen to web radio and also take calls from my business cell phone with a push of a button.

    Wireless Bluetooth wasn’t my requirement, but I’m glad it’s there.
    Most important to me is speach intelligibility, and the quality of my voice to others. I vouch for the first, and others have confirmed the second. I’ve read others’ reviews raving about the audio quality and I won’t contradict it. The audio is better than I can appreciate.

    While writing this I’m happily switching between Pandora and Live365 through my BlackBerry. Using my laptop Bluetooth I listen to Shoutcast or go directly to streaming websites. My new MM-400 handles it all.
