- Closed-back, circum-aural, deep-padded ear cups (best for ANC)
- 42mm transducers 6Hz-22kHz (best I have heard on BT)
The only problem is that the second you take them off the music pauses so we could not use a frequency response or decibel metre to measure.
Well, not quite. We discovered that you can disable Smart Pause in the app so see the frequency graph later.
But first, let me tell you about some of the tracks I use to test headphones and speakers.
The Blue Brothers Peter Gunn Theme
Those magnificent trumpets over a deep, bass, backbeat – Just the facts mam! I could listen to Blues Brother Jazz all day long.
These cans have a 6-22kHz frequency response (excellent). I felt the bass coming on strongly from about 40Hz – that is as good as a dedicated sub-woofer will do. I felt the trumpets hit previously unheard-of treble levels with pin-point clarity.
Note that I used the term ‘felt’ – you do not listen to Sennheiser, it immerses you. And with the greatest respect to Bose’s new 700 and Sony’s WH-1000XM3 – well, audiophiles, this is the best BT/NC I have heard.
Next track is the Beach Boys Fun, Fun, Fun that is a vocal track with electric guitars and synthesiser behind it.
On most headphones, it tends to be a little muddy as it favours high trebles. The Sennheiser Momentum 3 brings this track to life – it sparkles.
Finally, Manhattan Transfer Twilight Zone that also mixes voice and heavy bass as well as using the complete directional sound stage. Here is a 432Hz version (almost high-res).
The Sennheiser Momentum 3 aces this with the sound coming from a wide, no huge, sound stage.
Let’s just say that on a scale of 1-10 it’s a 12!
OK, back to the sound signature tests.
Maximum volume was more than 90dB on BT and 100dB on 3.5mm cable depending on content and the source device. That is a good 10dB more than the Sony or Bose but you
The cable connection is superior to Bluetooth and better than the Sony or Bose in sound quality and volume.
