1MORE Crystal Piston In-Ear Headphones
| Dynamic Driver | Swarovski Crystals |
? 1MORE Crystal Piston In-Ear Headphones (also known as 1MORE Swarovski Crystal), a special earphone designed with Swarovski Crystals. In case that you are wondering; no, pink is not the only color available.
The 1MORE Crystal Piston In-Ear Headphones features metal housings that add to them a nice robust touch and have a rear section made with SWAROVSKI ® ELEMENTS (specifically a 2035 Chessboard cut design). These Swarovski details give a very attractive look to their design which can make the pink version (as the one that we are reviewing) an incredible gift for your girlfriend or wife. Valentine’s Day is around the corner… wink wink.
The cable of the 1MORE Crystal Piston In-Ear Headphones has 2 sections built with different materials, one is braided and the other one is rubberized; this is a cable style that we have seen in the Xiaomi Mi Pro HD, Xiaomi Mi In-Ear Headphones Pro
, 1MORE Piston Classic
, Xiaomi Mi Noise Cancelling Earphones and Xiaomi Mi Noise Cancelling Type-C Headphones
, for example.
The cable holds a mic/remote with 3 buttons that will allow you to change volume, skip songs, play/pause music and answer/reject calls; the 1MORE Crystal Piston In-Ear Headphones is compatible with Android and Apple devices.

Accessories & Packaging
The 1MORE Crystal Piston In-Ear Headphones unboxing results in 3 pair of translucent eartips, a metal cable clip, a nice soft carrying pouch and a very neatly designed hard carrying/storage case that resembles the crystals rear section of the earphones. Everything comes packed inside a well-built sliding packaging.
10/10

B
Bass & Sub Bass
The 1MORE Crystal Piston In-Ear Headphones bass is rich and punchy with energetic mid-bass and deep enough sub-bass. The bass coming from these earphones will provide as much energy and fun as needed for any music genre but there are bassier earphones out there.
Applying an EQ, they gain a substantial amount of depth and some extra punch too but things will get a bit boomy.
During our extreme bass tests the 1MORE Crystal Piston In-Ear Headphones handled 40% of a Fiio E12 Mont Blanc (high gain, bass boost on, basshead EQ) becoming highly punchy and crazy deep reaching even a mild basshead rumble and impact but still not being able to reach the baseline basshead impact of the KZ ATE
and nowhere near the Xiaomi Mi In-Ear Headphones Pro, SONY MDR-EX650
, KZ ZST
, Senfer 4in1, KZ ZSR
or SONY MDR-XB50
.

M
Mids & Vocals
The 1MORE Crystal Piston In-Ear Headphones mids are warm and smooth but lower vocals could sound somewhat distant depending on the track and your SQ expectations; higher mids are less rolled-off than lower mids providing enough crispness.
With an EQ, their lower vocals sound much more alive and less congested, higher mids will still do not get too harsh.

H
Highs & Treble
The 1MORE Crystal Piston In-Ear Headphones highs have some brightness and are able to resolve very marginal detail. No piercing highs will ever be perceived and sibilance will be mild.
An EQ adds a huge amount of extra brightness but no additional detail. No piercing highs will arise; sibilance will get stronger.

SL
Sound Leak
The sound that leaks out of the metal earphones is slightly stronger than on some average earphones, falling just a bit behind.

SI
Sound Isolation
Noise isolation is strong, higher than many average earphones. A low volume can be set and the 1MORE Crystal Piston In-Ear Headphones will have a fairly effective level of isolation.
8/10

C
Comfort
With a very similar size and shape to the 1MORE Piston Classic In-Ear Headphones, the 1MORE Crystal Piston In-Ear Headphones provide also the same excellent fit and comfort level. No discomfort or soreness issues will ever arise while wearing this earphone.

EQ
Response to Equalization
The response to the EQs applied during our tests was quite efficient making them gain a substantial amount of brightness without introducing stronger piercing highs, mids benefited from much clearer lower vocals with more energy and less distant sound, bass became much deeper and punchy but also bit boomy.
