Mutrics continues the soundglasses trend

Manufacturer: Mutrics

Mutrics are smart audio glasses – or as GadgetGuy has dubbed it and Bose Frames – soundglasses.

Mutrics are functionally equivalent to Bose Frames (review here), and both have strengths.

For example, both have

  • Polycarbonate matte nylon frames
  • Interchangeable nylon lenses UV400 lenses
  • Voice assistant and hands-free calls
  • Open ear wearable audio
  • Mutrics is 50g (Bose is 45g)
  • 2-hour charge via each’s proprietary USB-A to magnetic charge cable

Mutrics also has

  • Qualcomm Bluetooth 5.0 and aptX for 20-metre range (Bose BT 4.2/SBC/9m)
  • Three-button control (Bose one)
  • No app (Bose has iOS and Android app, but it is not mandatory for straight BT use)
  • Eight hours battery (Bose 3.5-hour)
  • IP55 sweat resistance (Bose IPX2)
  • Choice of coloured frames – black, orange and white (Bose is Black Nylon but has a choice of Alto or Rondo frames)
  • Virtual 5.1 sound with passive radiators (Bose is 2.0)
  • US$129 – or buy three and get one free (Bose is A$299)
  • Lenses US$10 (Bose is A$29.95 to $49.95)

No this is not meant to be a shootout – Bose buyers are a breed unto themselves and want the brand cred that Bose brings.

Mutrics, on the other hand, is relatively unknown and started life in 2017 as a Kickstarter project. This is its fourth-generation product debuting at CES 2019.

Putting both side-by-side they look like they are from the same stable. OK, this is a Bose Frames shootout!

Looks

Black nylon frames with no adjustment for the nose bridge or arm length.

Bose are slightly more stylish, and I do not like tye Mutrics blue lenses (as reviewed) – but you can order them with a non-polarised grey lens.

You can fit prescription lenses without voiding the warranty.

Summary: Bose is a little more elegant (if that is the right word).

Fit/comfort

Mutrics is 159mm deep compared to Bose Alto at 162mm.  The arms (ear hooks) have rubber grip pads making them a little less likely to slip off your nose that Bose. 

Both the Bose Frames and the Mutrics are non-adjustable and unless you have the perfect head size will slip off your nose bridge. An optometrist should be able to apply gentle heat and radius bending to make the ear hooks a better fit.

Mutrics

Build

We repeat the warning that these are sunglasses and lenses can scratch.

Mutrics is IP55 rated. The first 5 means the prevention of ingress of dust must be sufficient so as not to interfere with the satisfactory operation of the equipment. So, you can wear these to the snow or desert.

The second 5 means water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. It is rain/sweat resistant.

The hinges are nylon with a metal pin and tension screw to tighten the arms. Bose hinges are metal with a tension screw.

Summary: Mutrics IP55 versus Bose IPX2 is a strong incentive. Both have similar lasting quality.

Bluetooth

Mutrics

Mutrics uses a Qualcomm BT 5.0 chip with aptX high-def sound and Qualcomm cVc noise cancellation technology. No, they are not noise cancelling – no open ear headphones can be. cVc helps for handsfree calls and automatic gain in noisy environments. It is married with a TI amp and DSP to produce virtual (not real) 5.1 sound.

The Qualcomm SoC has up to 65% lower power use (than BT 4.2), which accounts for the exceptionally long 8-hour battery life.

As it is industry-standard, it will pair with any Bluetooth source device without an app. Bose Frames has an app but its not necessary for straight BT use.

Controls

It has an on/off button (as well as auto power off) and up/down volume buttons, and these are for accepting/rejecting calls, playing music (forward/back) and accessing the voice assistant.

Bose uses one context-dependent button. I prefer three buttons.

Battery life

The 140mAh battery takes a 5V/.5A to 5V/3A charge via a USB-A to a proprietary magnetic clamp.

Claimed battery life is 8+ hours.

Over five days of walking for a total of four hours, the charge level is 40% – pass.

Recharge for that 60% took just over an hour with a 5V/2A charger – pass.

Summary: Bose has a 3.5-hour battery, and if battery life is important, Mutrics has over twice the life for the same charge time.

 Sound

These are ‘open-ear’ meaning you can hear your surrounds clearly.

Mutrics claims virtual 5.1 sound that means Left/Centre/Right, Left/Right Up, and a sub. The claim is (impolitely) ‘hyperbole’.

The tiny speakers sit in the arms and give a decent left/right sound stage – separation is not as wide as over/on/in-the-ear phones but nor should you expect it to be.

Mutrics

But unlike the Bose where the sound appears to emanate from within your head, these have a far better L/R separation, and wider sound stage (music appears to come from outside your head), e.g. sound has more directionality.

It is not a ‘full’ sound that you would expect from over/on/in-the-ear headphones, but it is surprisingly listenable with good crisp vocals, just enough bass and treble.

We could not measure frequency response or volume as our test equipment is just not up to that task. So subjectively (using bass tracks, vocals, and symphony):

  • Low to mid-bass is non-existent (from 20-100Hz)
  • High Bass starts to kick in (100-200Hz)
  • Low mids are building (200-400Hz)
  • Mids are strong (400-1Khz)
  • High mids (clear voice) are strong (1-2kHz)
  • Low treble is there but recessed (2-4kHz)
  • Treble – almost gone (4-6kHz)
  • High treble and dog-whistle – non-existent (6-20Khz)

This is a mid-sound signature that is an OK for voice, podcasts and most music.

When walking in relatively quiet suburban areas, the sound is clear, although louder passing cars can drown out the volume. If you are in quieter surrounds its fine. It works well for hands-free calling.

We could not measure volume, but it is a little lower than the Bose. At full volume (approximately 80% Bose) it has a relatively clean sound.

Sound Summary: While it is not what you would expect from over/on/in-ear headphones, it is quite pleasant. Bose wins by a whisker here, but you would expect it to.

GadgetGuy’s take – Mutrics is part of this new soundglasses genre.

I think soundglasses are perfect for walking and if the lenses were right, office use too.

While Bose has brand credibility, Mutrics has the technology edge and its about two-thirds of the price. On that basis, it gets the tick and is a strong contender for Bose Frames.
