If you hold down the Bluetooth button when connected to an iPhone it activates the Voice Control so you can even select your tracks by name!

This is Sennheiser’s third generation of Bluetooth headsets and takes advantage of all the latest developments available in wireless technology.

The rechargeable battery is removable and should last for two years on average, depending on usage. It is called the BA 370 PX and is easily available. To fully charge the battery via USB or mains will take about 3 hours. You can then listen to music for a full 10 hours (8 hours if the noise-cancelling is switched on) or talk for 20 before having to re-charge!

To hear the full audio potential from your computer or audio device with a USB socket, Sennheiser recommends using the BTD 500 USB (a USB dongle accessory), to ensure the source is apt-X enabled

Sennheiser recommends this headset for...

... owners of the latest Bluetooth apt-X-enabled phones and laptops, such as more recent MacBooks, selected HTC or Samsung Galaxy music products, who would like to take advantage of their full audio capability. Also perfect for those wanting a high sound and build quality in a more convenient format.


The MM 550-X offers excellent compatibility with all Bluetooth apt-X-enabled mobile smartphone brands and computers.

For the first time in 30 years of buying Sennheiser headphones, I find myself having to return a pair of Sennheisers for a refund. I'm a big Sennheiser fan; I currently have the HD 595 for the Hi Fi, the HD 380 Pro for work, the MM 450-X when mobile, and the PX 100-IIi as a spare. I've owned many others over the years.

I um'd and ah'd for several weeks before deciding to take the plunge and buy the MM 550-X, having mainly been influenced by the excellence of the MM 450-X - I wanted a larger version of the 450 with the same functionality.

First impressions
When they arrived, I paired them with the BTD 300i APT-X adapter plugged into the iPad and fired them up. Setting up Bluetooth devices is simple, as long as you look at the instructions first. I thought the sound was a little hollow immediately, but I just thought they'd need to be run in a bit. I thought the build quality was excellent, and they are very comfortable. I imagine they could be worn all day without discomfort.

NoiseGard: noise cancellation
I carried on experimenting with with the settings on different music types, and with different settings on and off, and the results were always the same: with NoiseGard turned on, the sound quality is more like AM radio; it was as if the life had been sucked out of the music. The only near-acceptable configuration for noise cancellation is when using a wired connection. This completely misses the point for travel headphones: many users will want to use them without wires, and having a wired connection prevents the use of the headphones for calls. In each case, NoiseGard seems to hollow out the sound, a bit like boosting mid-range frequencies while leaving bass and treble slightly down.

Best place to start with these headphones is the price point, its a little high but you do get exactly what you pay for.

The sound quality is excellent and the issue with volume actually is not a problem, at least not for anything I have used the headphones on, through bluetooth I simply max the volume on my phone / bluetooth dongle and then use the volume control on the headset, and the headphones actually hurt my ears on full volume I am forced to lower it down slightly. (I have sensitive ears but these are no means quiet.)

Wired the headphones run in two modes, wired passive (Battery on charge / turned off.) In this mode the audio is passive and though great quality the volume is limited by the power of your device attached and thus i found for phones and similar the volume though fine could not get loud enough and none of the extra features such as noise guard functioned. (However it does tell you this in the manual and was expected.)

Wired + power, turning the headphones on so they are active rather than passive allows the volume to reach ear hurting levels once again, and the sound is beautiful, you can now use the noiseguard feature and the SRS feature and the sound quality even with eveything enabled is amazing. (Sound quality is best without noise guard and srs, but in a noisey environment they are very useful and work brilliantly.)

Talking on the headset works wonderfully well and the headset itself is very light and covers your ears fully. The sound is the best I have heard over bluetooth reguardless of using APT-X or not, though when using the better codec the sound quality is just as good wired or wireless and these are an amazing peice of kit, so long as they are used properly.

Vine Customer Review of Free Product ( What's this? )
Having used a Sennheiser MM450 headset for over 18 months I leapt at the chance to try its bigger, updated brother the MM 550-X. These over-ear "full cans" look very similar to the 450s - same style buttons, in fact the same controls full stop, and the same battery, and don't weigh too much more either. In the box with the headphones is a nice carry bag containing some instructions (booklet and CD), USB charging lead, mains charger with a selection of adaptors, audio adaptors and a stereo cable. Again, similar to the MM450, and the similarities don't stop there.

Physically the 550s look good and feel like they have the same good build quality of the MM450, and having use the MM450 for as long as I have I found that the way it pairs, and the way the controls work, were identical (barring new features of course). The electronics have been updated, and these headphones also support a kind of surround sound (SRS Surround Simulation) as well as noise cancellation and hands free calling.

Before we get started using the headphones I'm going to cover the controls. They look a bit daunting to start with as there are seven buttons on the right earpiece that provide everything you need to work your headset. Sennheiser have clearly done some careful research here as it is easy to work out which button is which by touch.

The five buttons on the side control power, volume and next/previous functions. The central power button doubles, no, trebles up as play/pause when listening to music, and answer/hang up when calling while the two buttons on the bottom manage bluetooth, noise cancellation and other auxilliary functions via long and short pushes.

So once you've charged the battery, hold down the power button and the while plastic around it will flash blue.
