"Wireless, digital and over 10 hours between charges"

He Sennheiser MM400X Bluetooth Headphones are very much what you’d expect from their description, headphones, designed by Sennheiser, supporting Bluetooth apt-X protocols.

Advertising literature points out that these are primarily designed for ‘smartphones’ – although their use is not limited to this, indeed I have never actually used mine for this purpose.

The headphones comprise of a padded stainless steel headband, two ‘closed back’ sound units into which the electrics (including battery) have cunningly been concealed.

The phones can be folded flat, and can be stored in the profided zip-up black nylon case – along with the headphones come a standard ‘wall wart’ charger featuring a micro-USB charging lead, a number of international plug adapters (so you could connect to the mains in the UK, the European continent or further afield)

Especially handy is a patch cable, if your battery runs out, you can connect it directly to your audio device through standard 3.5mm stereo lack plug.

For normal listening, the battery will last around 10 hours, use as a ‘bluetotooth headset’ this increases to around a claimed 20h (presumably lower quality audio takes less power) and re-charge can be achieved in 3 hours, although I know this to be significantly les if you use a high current charger, although a shorter battery life might be anticipated.

The device is based on Bluetooth, which is a digital format. That’s digital in the same sense that it offers a broadly acceptable and reliable connection, but almost certainly falls short of ‘audiophile’ quality.

If you think MP3 files sound fine, or are intent on listening to speech-based content, they’re well up to the task. If you’re the sort that insists on storing digital files as ‘lossless’ in order to preserve the highest possible audio quality you might find these wanting,

It is easy to tell left and right sides apart; the left has a ‘plain’ back, the right has the
on/off and volume controls, as well as ‘transport’ buttons, which allow you to skip forwards and backwards (if your device allows this)

I use my headphones mostly at home, mostly on a Bluetooth connected PC and mostly at night when I don’t want to be running ‘open’ speakers and wake the rest of the family!

I paired my PC (a relatively painless experience) which was almost the same as establishing connectivity to a conventional monaural earpiece.

There are volume controls on the headphones, although I tend to keep mine set ‘full power’ relying on the Windows ‘audio mixer’.

Should you wish to use your headphones as a two-way headset and do phone calls etc, these have all the support you need, as hinted before, I have personally never used them for this but customer rvuews seem to give this the thumbs up

Range is typically ten or so metres, this allows you to have the PC at one end of the room and affords you the option to move around the room. Like all wirels devices, there is a limit to that range, and that is based on environmental factors – my house is built of pretty substantial brick, which plays havoc with wireless network connections but I can still hear audio content from the next room to the PC.

A rough cost, if oulook around, is about £140 sterling – not cheap my any sense, but the units have some distinct advantages;

They don’t tie you to your sound device by a cable – it’s possible to be listening whils moving around the room.

You can seemingly accept incoming calls, or indeed use them as microphones for video conferencing.

You are spared the problem of moving away from your sound source, and pulling it over because of a connected cable.

I find these comfortable, easy to use and the ‘listen time’ is sufficient for me to watch roughly a week’s worth of video on demand (most often iPlayer)

I have a slight hearing impairment (mostly tinitus) and use an aid, the 'over ear' format allows me to wear these whilst still still wearing my lug-bug.

Shoud the internal cell on the headphones, the patch cable is an added bonus, even with an entirely fat battery, the phones act as ‘passive’ units.

Sound quality is completely satisfactory – being relatively small, bass lines can be less than imposing but for general TV viewing, I have nothing to complain about.

The folding option would be handy f you are constantly on the move, but I just hang mine on a hook next to the PC monitor.

'Pairing' is entirlely straightforward, the instructions go into great detail, but in essence you charge the battery, spres the 'ON' button, and keep your finger on it until it flashes 'red/blue' like virtually other headset. You then go about "finding" the headset n your PC or smartphone and supply a code (from memory it was "0000" but that's detailed in the instructions).

Crunch time; would I recommend these? – I would give a qualified yes.

They’re not cheap, but have worked flawlessly for me over twelve months.

Audio quality is every bit as good as you’d expect for a Bluetooth devce (If I want to do ‘serious’ listening I still tend to reach for my ‘passive’ cable connected cans)

But overall, it delivers what it promises.

To that extent then, recommended.
