? 1MORE Piston Classic In-Ear Headphones, sometimes being named 1MORE Piston 2.

1MORE is a brand that specializes in manufacturing headphones and in-ear headphones (earphones, earbuds) and have developed some highly well established models like the 1MORE Triple Driver In-Ear Headphones and the 1MORE Quad Driver In-Ear Headphones. Moreover, 1MORE is the brand behind all of Xiaomi’s earphones; meaning that they are the brand that builds Xiaomi’s earphones which is a brand with many great in-ear headphones like the Xiaomi Mi PRO HD, Xiaomi Mi In-Ear Headphones Pro and the ultra budget Xiaomi Mi Piston Basic Edition and Xiaomi Mi Piston Fresh Edition, to name just a few of them.

The 1MORE Piston Classic In-Ear Headphones have a simple yet sophisticated premium look with piston-like housings that are robustly built in metal and have a very good finish. Despite the metal construction they are extremely light weight and as you might appreciate from the photos they are very small, similarly sized to the UiiSii HM7 or the Plextone X41M.

The cable has a section which is rubberized and another which is braided (a cable style that we have previously seen in our Xiaomi Mi Quantie Pro Hybrid Review), the combination offers quality feeling finish and effective anti tangling capabilities. The cables are rounded and a mic/3-button control is found inline (which is also the cable bifurcation section); the mic/control is built in the same metal material and quality as the housings and shares also the same finish and color. On the 3-button control you will find that the 2 buttons dedicated to change volume are on one side and the other remaining button that controls play/pause and answering/rejecting calls is on the other side. The stereo mini plug is also built in the same color, finish and metal as the housings.

Accessories & Packaging

You will get them in a packaging that resembles very much the one of the Xiaomi Mi Piston Basic Edition or the Xiaomi Mi Piston Fresh Edition but inside you will find a very nice hard carrying/storage case almost identical to the one that is provided with the Xiaomi Mi PRO HD; 3 extra pair of eartips and a metal branded clip are provided as additional accessories.

Bass & Sub Bass

Maybe you just peeked at the high score that the 1MORE Piston Classic In-Ear Headphones has obtained in this category and might think that, therefore, they must be bassy and high impacting earphones but instead they are quite the opposite offering a greatly well-achieved and balanced bass response with the right amount energy, punch and depth and are free of bass-bleed, boomy sound or any other issues that arise with bass-boosted earphones. At the same time you must not fear of getting an anemic or too conservative bass. It is for this reason that they have gained this well worthy score; also remember that, as we specify in our Earphones Scores Comparison Charts, a higher score in the Bass/Sub-Bass section does not strictly represent a stronger bass response or higher punch and depth. In fact, the 1MORE Piston Classic In-Ear Headphones are certainly not the best choice for bassheads or EDM music.

… a higher score in the Bass/Sub-Bass section does not strictly represent a stronger bass response or higher punch and depth.

Applying an EQ they can be boosted to provide a great extra amount of mid-bass punch and sub-bass depth making them much more party-styled.

Putting the 1MORE Piston Classic through our extreme bass tests they were able to handle a jaw-dropping 69% of the maximum power of a Fiio E12 Mont Blanc portable amplifier (custom basshead EQ applied, Fiio E12 set to high gain and bass boost function turned on).  The result of such a drastic amplification was a very strong increase of punch and depth but despite their insane amplification power capacity they did not achieve any type of basshead impact nor rumble, certainly do not expect an ear-exploding sensation as what you can get with the Xiaomi Mi In-Ear Headphones Pro or the amazing Pioneer SE-CX8 and Sony MDR-EX800st.

Mids & Vocals

As we just mentioned in the Bass/Sub Bass section, the 1MORE Piston Classic In-Ear Headphones are free of mid-bass bleed and so their lower mids are less prone to sound muffled. Despite this, there is some lower mids recession that could make lower vocals sound a bit distant depending on the type of music but in general they sound warm and smooth. Higher mids are not forward nor recessed and do not get harsh. With an EQ, lower vocals get bumped up and sound less distant while still not getting boxy; higher mids become harsh.



Highs & Treble

Highs have enough brightness and some detail that will probably make happy normal listeners that do not have audiophile expectations. There are no piercing highs but slight tiny sibilance may be perceived at times. Using an EQ, highs open up very noticeably with a clear added amount of brightness and substantial extra detail while remaining free of piercing highs and as sibilant as before.

Sound Leak

The sound that leaks out of these earphones is on par with most average earphones, setting a moderate volume they are perfectly usable in normal situations without disturbing anybody, for library use you will need to limit your volume to a very low setting.



Sound Isolation

Their capacity of blocking outside noises is very good, providing a noticeable level of reduction even while using a low or moderate volume.




The 1MORE Piston Classic In-Ear Headphones are wonderfully comfortable to wear, their small size and almost flush fit makes them perfect for a pain-free experience even after continuous hours.



Response to Equalization

The response to custom equalization was very effective if you want to brighten up the sound you just need to eq up the higher frequencies and they will clear up and reveal detail. If you want to make them more party styled bassy sounding, just emphasize frequencies below 125 or 80Hz and they will provide noticeably more punch and depth. Regarding mids, lower vocals got more lively and less distant but higher mids started to become harsh.
