Plextone X50M – Review

Plextone X50M

Plextone X50M

| 8 mm Driver |


? We have reviewed other Plextone earphones in the past and we were highly surprised by the quality offered at such low price, for example the Plextone X41M has gained a position in our Editor’s Pick couch and is also ranked as one of our Top 10 Basshead earphones and Top Fun Sound earphones. The Plextone X50M have an identically sized dynamic driver as the Plextone X41M and also share the same aluminum construction material, magnetic back housing and cable design. Whether if they both sound identical or not will be discovered during our tests results.

… the Plextone X50M left behind the piston-like design and opted for a more refined style…

Despite sharing some specs they have clearly different aesthetics, the Plextone X50M left behind the piston-like design and opted for a more refined style with a 2-piece metal housing and a classic bullet design that overall results in neat looks that make them seem a premium earphone. As we have mentioned before the cable is the exact same as the Plextone X41M, it is nicely designed, has a rubber anti-tangling material but it tends to preserve the winded form with almost no chance to fully straighten it up. The cable has an inline microphone and 1 button control and it also has a switch to select Nokia or iPhone compatibility. Plextone is selling the X50M in a green/gray color or in gold/gray combination (like the one we own), cable color pattern matches the color of the housings selected.

Accessories & Packaging

The Plextone X50M come inside the typical cardboard box provided with almost every Plextone earphone (nothing fancy), 2 extra eartips and a cable clip.



Bass & Sub Bass

Bass coming from the 8mm dynamic driver of the Plextone X50M is rich, punchy and fun with very deep sub-bass that is stronger than mid-bass punch but out of the box they are not as powerful, impacting and deep as the Plextone X41M. So, despite sharing the same driver size they do not seem to use the exact same driver or maybe the acoustics of the housings are making them perform differently.

… the Plextone X50M is rich, punchy and fun with very deep sub-bass that is stronger than mid-bass punch…

Nevertheless, the Plextone X50M still have a great quantity of bass with enough strength to comply with the bass requirements of any music genre, even with highly bass demanding music. After an EQ, they got noticeably punchier and deeper, approaching a little more to the performance of the Plextone X41M. Under our extreme bass test (custom basshead EQ, extreme amplification with a Fiio E12 amplifier set to high gain and bass boost on) the Plextone X50M were able to handle up to 72% of Fiio’s maximum power, which is almost identical to what the Plextone X41M were able to take. As a result you can expect an incredible increment in mid-bass punch and sub-bass depth and an outstanding basshead impact and rumble level above the KZ ZST, KZ ZS2, Xiaomi Mi Quantie Pro Hybrid, similar to the Senfer 4in1 or Doboly Q18 and below its brother, the Plextone X41M.

Mids & Vocals

Higher mids of the Plextone X50M are a bit forward and can become a bit harsh. Lower mids have a slight recession but not too much, this recession can make lower vocals sound a bit distant at times. The X41M had slightly better mids but with a similar sounding style. With an EQ, mids removes almost every hint of recession but become harshier.



Highs & Treble

The highs of the X50M are bright and have the ability to reproduce some detail but not too much. Unfortunately, highs become piercing with high notes and can sound sibilant at times. For treble sensitive people the Plextone X50M might be fatiguing. Equalizing, a great amount of brightness and detail is gained but with more frequent piercing and sibiliant highs.  



Sound Leak

The sound that leaks out of these earphones is fairly reduced. They might not qualify as a perfect companion if you intend to use it at libraries but they offer enough privacy on mediumly noisy environments.



Sound Isolation

The Plextone’s do a reasonable job blocking outside noises. Sound surrounding you will get reduced but higher volumes are required to isolate better.




The X50M are very comfortable to wear for short or long sessions; they are toughly built and at the same time lightweight. Fit is firm and not invasive, they will hold their place under normal use. The bullet design protrudes from the ears just a bit and makes them easy to grab.



Response to Equalization

The Plextone X50M showed a respectable response to custom EQ, bass became very noticeably punchier and deeper without sounding muffled; mids removed most of their lower recession but introduced more harshier higher mids; highs gained a lot of brightness and a fair amount of detail but became strongly piercing.

We highly discourage anyone from trying to apply our testings to your own earphones, the risk of damaging or permanently breaking your iems is absolutely probable to happen. With our standardized equalization and amplification tests we push the limits of the earphones to the extreme. If anyway you decide to do so, we cannot be held responsible of the damage done to your equipment. Do it at your own risk.
