I’m not a huge fan of wireless headphones. I love the idea and I’ve tried quite a few, but I always switch back to wired in-ear headphones, my favourite being Sennheiser’s M2IEG Momentum, reviewed as excellent last year. The Momentum Wireless has won me over in the last two weeks. It’s beautiful with  a nappa leather neckband and a mirrored chrome finish. The sound quality is unlike any bluetooth devices I’ve tried. It’s crystal clear, balanced and paired to the iPad, I played Osmos and realised it’s soundtrack had undertones in it I’d never heard before. It pairs easily, fits snuggly and I don’t feel weird wearing them in public – the neckband fits nicely underneath the collar of my black coat and the earbuds have just enough cable to dangle without getting in the way.

The Ergohacks Verdict

This is one of those items where I struggle to write about it without sounding like an bad advert. I just like it a lot. In two short weeks its moved up to share the top spot with my wired headset – I do still prefer the M2IEG Momentum when out and about because I have neck issues and wearing something around my neck when walking, moving and bending all day isn’t ideal, but I wish I didn’t because it’s much easier to remove and replace these – I never loose the cable, it’s fantastic.

I often wear only one earbud so that I can hear insulin pump alarms, the mild mannered protests of our disabled cat scratching when she gets stuck somewhere, the phone or the door. I’ve been making the effort to wear these as much as possible using both earbuds for testing and have come to the conclusion that I’ve been neglecting good sounds in my life. There’s more to sound than audible pump alarms!

I’m listening to music again. I’m downloading podcasts and breezing through audio books. I’m watching a bit of TV late at night when I’m awake anyway and I’ve streamed some nature sounds whilst completing up my creative writing project for my university degree. Sound isn’t always easy to access with some hearing issues. The Momentum Wireless has been a joy to use with both the iPad and my phone. It’s noise cancelling drowns out background noise whilst it’s sound quality is excellent for everything – sound effects, speech and music. The battery lasts, pairing is easy and it’s beautifully made to last.

I’ll keep my wired headset for migraine days in bed – it’s not comfortable to wear lying in bed – but for everything else – at home and away, I’ve been won over to the wireless side of sound. It’s a mid-range headset, retailing for around £170. Not a budget item, but for those willing to pay for excellent sound quality, luxurious comfort, a top notch battery that extends listening time to 10 hours and are looking for a high quality, durable product, you will get what you pay for. Highly recommended.

Sennheiser’s headphones are always well-designed and the Momentum Wireless is no exception. The neckband is covered in nappa leather for a comfortable fit and buttons are located on the interior on the right side. The cabling is red and black with a mirrored chrome finish on the earbuds. Four sizes are included and although it’s a product manufactured for adults, our six year old gleefully helped with the testing by wearing them as she watched My Little Pony. She swapped over to the smallest adaptor set and was amazed that they fit quite comfortably and didn’t fall out. I’ve been using the small, Chris switched over to the large when he borrowed them on holiday and it’s been a comfortable wear for all of us.

The case is wonderful to have. I threw it in a suitcase next to insulin vials and infusions sets as I speed packed last weekend for a short break in Dorset. They arrived unscathed and good as new, although the case did pick up a bit of fluff, cat hair and beach sand despite not actually taking it to the beach. I do feel more comfortable keeping them in the car during longer journeys as I can pack them up safely when not in use. It’s a hard shell case that flips open fully and even at home they store well within the case – I just don’t zip it up. There’s no fiddling to get it to fit in – the case is moulded to its shape and brings the added convenience of a good place to store the cable and ear adaptor sets not in use so I don’t misplace them two days after I get the headset  – never to be found again.
