We spend some time focusing on 1MORE's Dual Driver In-Ear
Headphones. We can say straight out that these are incredibly good
for the price.
With the 1MORE website claiming that this product contains a
dynamic driver that takes care of bass and an additional balanced
armature driver to provide mid-range and treble sound, this dual
driver in-ear audio solution is vying to become your next audio
While 1MORE may be a new brand to most people reading this review,
I was thoroughly impressed by the packaging, accessories, comfort,
and performance that my previously reviewed 1MORE Crystal Piston in-ear solution had to offer. I'm interested in seeing whether it was a 'one hit
wonder' product or whether 1MORE will continue this performance.
Other than pure sound quality, this review will be looking at the
build quality of the unit, what accessories are included, the
asking price, and many other important factors.
Mirroring the technical specifications of the Crystal Piston
offering, the Dual Driver in-ear offers a sensitivity of 97dB, a
standard frequency response of 20Hz - 20KHz, and an impedance of 32
Weighing in at 15 grams in total, 1MORE has included a 1.25 meter
enamelled copper wire with this product, providing a braided cord
exterior that splits into two rubber coated cables that lead to the
earpieces. Capable of functioning with most Android and iOS based
devices, this unit connects through a single 3-ringed (4 pole)
connector that carries audio and microphone signals through a
single connection. Providing an in-line control unit that allows
users to play, pause, adjust volume and answer calls, this product
further comes with an attached microphone for hands-free phone
Pricing & Availability
While the two-in-one package of the Crystal Piston is priced at
$79.99, expect to pay $59.99 for this Dual Driver unit from Amazon,
including free shipping to your door. This price point places the
Dual Driver earphones directly into the mid-range of consumer
audio. While it is a little more costly than offerings in the
gaming scene from the likes of Razer, Roccat, Tt eSPORTS, and more,
this price tag is firmly in the middle ground when having to
compete against the likes of Sony, Bose, and Sennheiser.
For $59.99 and looking at competing with some of the world's top
brands, I would come to expect a refined package that offers handy
accessories for daily or consistent use.
What's in the box?
Once again providing an exceptionally laid out and well-presented
package, 1MORE has included just about anything you need with such
Besides the supplied user manuals and warranty information, 1MORE
provides a useful set of handy accessories that are presented
beautifully within the well-padded packaging. It's not often that
I'll make mention of the packaging at all, but 1MORE has done a
brilliant job here with presenting and protecting the components
within, similar to how Razer will often blow away its competition
in the gaming peripherals scene.
Included in the overall package is a small leather protective carry
pouch, three differently sized rubber ear grommets for comfort, a
little metal cable clip to keep things tidy, and an aircraft
adapter for those who like to travel. While these accessories look
extremely well built, for the most part, I would have liked to have
seen the aircraft adapter adopt the top-facing brushed metal look
to help it synergize with the clip.
The carry case is hard leather in design and quite different to
most other in-ear offerings, this ensures that your product is
completely protected from being crushed or scratched, but may be
uncomfortable for some if you're intending to carry it in a pants
Let's dig deeper
Providing yet another strongly built product, 1MORE has once again
opted to go for a combination cable covering of braided cloth on
the single lower part of this product, splitting into two rubber
coated cables that run to each earpiece.
Using this product for an extended period didn't make me run into
any comfort issues with these off-centre earpieces, opting to use
the medium pre-installed grommets for regular use. I had issues
with the 1MORE Crystal Piston earphones in the fact that the rubber
was too smooth and prone to sliding out of my ear. This wasn't
present in the Dual Driver model, but I did experience slight
initial discomfort on cold
