Sound signature was – whatever you want it to be! We tested with the flat EQ and
- Deep Bass: 20-40Hz – none
- Middle Bass: 40-100Hz – building and quite strong
- High Bass: 100 to 200Hz – flat (that means good)
- Low-mids: 200-400Hz – flat
- Mids: 400-1000Hz – flat
- High-mids: 1-2kHz – flat
- Low-treble: 2-4kHz – flat
- Treble:4-6kHz – flat
- High Treble: 6-10kHz – a slight decline*
- Dog whistle: 10-20 – peak and decline after 18kHz
*The decline from 6-10kHz is deliberate to remove the harshness or harmonic resonance that occurs in that band – very well done.
This means it neither adds nor subtracts from the source content and you can boost the bass, mid or treble accordingly. The Bose 700 sound signature is very similar, but its treble is not as strong.
So, it verges on warm and sweet (flat EQ) and can change to Bass, Mid or Bright vocal – very flexible and very listenable!
The App – Sennheiser Momentum 3 Smart Control
You don’t need the app to pair or use the device. But it adds a few extra features like an Equaliser (EQ) and for the occasional firmware updates.
This is not an obtrusive app – it does not ask for age, gender, address, bank account… It just needs BT access and optionally location.
The EQ is interesting. It defaults to flat, and you simply drag the curve up or down. It suggests that you play your favourite track and see if you can improve on it. While I may like the preciseness of Sony’s +/-10dB adjustment scales this is a fresh way of enhancing the sound. It turns out that flat is perfect anyway.
But if you are hearing impaired, you can match the curve to your hearing test, and that is wonderful if you have lost high, mid or low-frequency sensitivity. The settings remain on the headphones until you change or cancel them.
Ease of use
While I have grown to like touch-sensitive controls, many people prefer buttons. These are straightforward and logical
- ANC off/on/transparent
- Volume +
- Volume –
- Answer/reject call or pause music
- Voice assistants (Google, Alexa and Siri) and Bluetooth pairing
BT 5.0 – amazing
BT 5.0 puts earlier versions to shame for fidelity and range. Fidelity in that it can handle 2Mbps data stream allowing for HD or Hi-Res music streams at distances of up to 240 metres from the BT source (in practice 100m). With BT 4.2 the maximum (in theory) is 60 metres, but I find 20-25m is tops.
It also has NFC pairing (straightforward) and supports SBC, aptX, aptX Low Latency and AAC (so Apple users will love it). It can pair to up to eight devices.
If you have a BT 5.0 source, it will connect reliably and blazingly fast .
It has four ANC mics and two additional beamforming voice mics. That is like the Bose 700 (4 x ANC and 2 x beamforming) and it is very effective.
My favourite test uses an old clackety SteelSeries mechanical keyboard at 30cm from my head. The clackety keys reach 75dB at 100wpm touch typing – the same level as busy streets or alarm clocks. The ANC setting (off/ANC/transparent hearing) completely blankets the keys.
Another test is to have my wife talk to me from about 5 metres away. I cannot hear her at normal conversation levels and can barely hear her on the rare occasion she is shouting.
