JBMMJ MJ8500 – Review



| 9 mm Driver |

? The JBMMJ MJ8500 earphones are part of the large catalog that JBMMJ offers. We own and have previously reviewed other earphones from them like the JBMMJ MJ007 or the bigger brother JBMMJ MJ8600, and we were very satisfied with their price-performance and design. Both the JBMMJ MJ8500 and the JBMMJ MJ8600 share the same size of dynamic driver so we will see if they are a just a MJ8600 repacked in a different housing or if they have something different to offer.

The JBMMJ MJ8500 are made of aluminum with every single detail like the plug and cable bifurcation made of the same material

The JBMMJ MJ8500 are made of aluminum with every single detail like the plug and cable bifurcation made of the same material, the metallic material makes the MJ8500 solid but still light. The cable is rounded and rubbery to fight against tangling issues, the cable is thick and feels robust. The JBMMJ MJ8500 have beautiful colors with a shiny finish, besides the golden one that we bought there are: a coffee colored which looks very slick (the same color as the JBMMJ MJ8600 unit that we reviewed in the past), a silver one and a grey one without a shiny finish.

Accessories & Packaging

The JBMMJ MJ8500 unit that we bought came in a zip lock bag with no extra accessories but we know that a full package version can be purchased and comes with a large amount of accessories included.



Bass & Sub Bass

Mid-bass and sub-bass coming from the JBMMJ MJ8500 is not too strong or punchy nor too deep but it still has a good quantity of bass for most genres. If you are searching for a super bassy earphone the MJ8500 will not make you happy. If your preference is a bassier version and want to consider another earphone from the same brand, the JBMMJ MJ8600 will match better the bassy profile.

If your preference is a bassier version… the JBMMJ MJ8600 will match better the bassy profile.

After applying an EQ the JBMMJ MJ8500 became punchier and with deeper sub-bass but everything else turned up way too muddy. Putting the JBBMJ through our extreme bass test they handled 48% of a Fiio E12’s maximum power (the amplifier was set to high gain, bass boost turned on and a custom basshead EQ was used) and gained much more punch, sub-bass got deeper too but distorted. Bass rumble and impact was similar to the level of the Panasonic ErgoFit RP-TCM125, JVC Gumy Plus HA-FX5 or the Panasonic ErgoFit Plus RP-HJE190, above the Philips SHE3580 or the Panasonic RP-HJE120 ErgoFit and way below it’s bigger brother the JBMMJ MJ8600.

Mids & Vocals

Mids are too laid back and recessed mainly on lower mids, higher mids can become harsh at times. After an EQ was used, lower mids became less laid back but started to sound boxy and much harsher. Once again the bigger brother (JBMMJ MJ8600) performed better on this audio frequency.



Highs & Treble

Highs of the JBMMJ MJ8500 have enough brightness and some detail. In general they are not too piercing but suffer from sibilant highs. With an EQ a lot more of brightness is gained but no additional detail or definition is added. In this audio frequency the JBMMJ MJ8500 performed better than the bigger brother.



Sound Leak

Sound leakage of the JBMMJ MJ8500 is slightly better than most average earphones that we  reviewed, not exceptionally superior but a tad greater performer, were sound levels leaking out from them got reduced and attenuated to the degree that makes them usable in mediumly noisy environments without disturbing people nearby.



Sound Isolation

In the case of sound isolation the JBMMJ MJ8500 performed worse than most average earphones, requiring mediumly high to high volume levels to be efficient isolating you from noises (of couse, this could be a positive aspect if that is what you require)




The JBMMJ were able to please us with great comfort, no sore ears even after long listening sessions and enough tight fit to wear them without worrying about them falling from your ears. Their fit is tight enough for normal usage but probably not for sport activities, there better fitted earphones for sports and high intensity activities like the Puma Bulldogs or the KZ ZS3, even the JBL T110 would be better suited for this.



Response to Equalization

The response to custom equalization was below average showing some improvement over the diverse audio frequencies but also introducing undesired harsh and boxy mids and a very muddy sound signature.
