What customers say about "Key Specs"
Audio-Technica CKR7TW Full Wireless Bluetooth Earphone
  • Battery life is very good. I am impressed with the sound quality comparing with my wired earphones.
  • The sound quality is pretty good as well as the long, the magnetic dock works well, battery life is long.
  • The battery life is about 4 hours of constant use, which is decent.
  • Apart from that the battery life is good, the sound on playback is also good and the range was fine.
  • Overall, sound and the novelty of not having wires is nice. But battery life, fit and practicality lose some.
Sennheiser Momentum True Wireless Bluetooth Earbuds with Fingertip Touch Control
  • I primarily use these when working out at the gym. The low frequency bass is banging! Awesome. And the high frequencies have such good clarity.
  • The sound depth is amazing. Completely immersive! The noise cancellation is 1st class.
  • The soundstage is big and airy and the thumping low bass complements the clear higher frequencies.
  • The sound quality and detail from these earphones are the best I have ever heard.
  • There seems to be some distortion and crackling with longer high frequencies.

Sennheiser Momentum True Wireless Bluetooth Earbuds with Fingertip Touch Control
  • The units them self feel very well built and have a correct weight for its size.
  • The small size and weight mean they are comfortable and unobtrusive.
  • The size is good and comfortable, although I like it you will be looked in the streets because they look like you have earplugs.
  • The case is compact and a perfect size for pockets or bag storage while out and about with you.
  • Only complaint is that for nearly £300, the nearly all-plastic design of the earphones and case coupled with their light weight make them feel somewhat cheap.

What customers say about "Features"
Audio-Technica CKR7TW Full Wireless Bluetooth Earphone
  • Although they are obviously not true "Active" noise cancelling earbuds, these fit snugly into the ear canal and cut out a lot of the outside sounds you would normally hear with headphones or earphones.
  • The earbuds fit snugly and I found that no amount of shaking my head about or running on the treadmill dislodged them which is great if your exercise/workout is an intense and vigorous one!
  • I didn't feel any discomfort from wearing the earbuds over a prolonged period.
  • These have a 24 bit DAC, but only support 16 bit AptX, NOT AptX HD....which cripples the whole point of using a high end DAC.
  • Notice how there's no IPX water resistance rating? That's because, in a time when $40 earbuds can be fully submerged, these pricey earbuds may not even be sweat tolerant.
Sennheiser Momentum True Wireless Bluetooth Earbuds with Fingertip Touch Control
  • The connection has been so stable. The control design is lovable. The designers truely understands remote control and whats most convenient way to do so.
  • Great fit. A little large but fine. Connection is generally stable.
  • Bluetooth connectivity is great and haven’t had any signal drop-outs. Battery lasts for around the stated 4 hours.
  • Excellent sound quality, decent noise cancellation and maintains good connection.
  • One small issue, the app on IOS is rubbish, even when the headphones are connected via Bluetooth the app still won’t find them.

  • The battery life is surprisingly long! I absolutely love it. I have managed to use them for 3 days (many hours) without charging.

  • If you want full battery life you will need to carry charging case around.
Sennheiser Momentum True Wireless Bluetooth Earbuds with Fingertip Touch Control
  • A 4H battery life plus charges from the case is more than enough for what they were designed for.
  • The battery is ok. These are great for easy listening, travels etc.
  • The battery life seems fine, I haven't been anywhere near running out of juice and only need to charge the case every few days.
  • Overall a very good product, sound quality is great, isolation is great, it looks good, battery lasts reasonably long.
  • When the case is fully charged, this will allow 12 hours use, and this is 4 hours with the ear buds and an additional 8 hours rechargable with the case. Charging is very fast.
