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
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
We repeat the warning that these are sunglasses and lenses
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
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.
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.
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
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.
These are ‘open-ear’ meaning you can hear your surrounds
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.
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
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
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.

Open ear audio is good for walkers
Three control buttons are easier
Sound is as good as it gets for soundglasses - particularly in aptX mode
BT 5.0 and aptX is impressive
Great battery life
Won’t replace your existing headphones – more supplement them
Uses a proprietary charge cable
Could do with a little more volume - its not an issue
