We had more fun with this IEM than we expected.
Differentiating yourself in the budget IEM market is crazy hard and the Mee Audio M6 Pro 2nd Generation is competing right in the midst of it. At the ~$50 price range, you get companies like KZ who is able to pump out multi-drivers IEMs (See KZ AS10) at dirt cheap price.
Mee Audio positioned the M6 Pro as a professional monitor earphone for musicians. It further reinforces its seriousness on music with its IEM design and included accessories.
At the end of our review session, we weren’t too sure if it was indeed musician-worthy. But one thing for sure, we ended up finding the M6 Pro more fun than expected.
- Detachable Cable
- Both stereo cable and headset cable provided
- Custom faceplate
- V-shaped sound signature
- Strong punchy bass
- Not so pleasant-looking circuitry
- Unfriendly 2mm DC connectors
- Flat background detailing
- Good quality packaging
- Additional cable with mic provided
- Comply foam ear tips
- 6.35mm adaptor
- No balanced cables options available
Instead of the usual flimsy packaging that you normally find on budget IEMs, the M6 Pro has actually put in effort in their package design. It comes in an attractive-looking packaging that is made from cardboard that doesn’t feel like it’s going to crumble with some pressure.
The cables of the M6 Pro is designed to be detachable. So what does that means for someone who is looking for a monitor earphones?
If you want to switch to a single-ear monitoring mode, you can detach the stock stereo cable and attach it with a stereo-to-mono cable.
A 6.35mm (quarter-inch) adaptor is something rarely included for IEMs, even the expensive ones. I guess this inclusion is a statement for them to stay in line with the “professional monitor earphones” theme.
Unfortunately, unlike their other models which supported MMCX connectors, the M6 Pro uses 2mm DC connectors. There are currently no balanced cables that supports that connector.
“I’d also just like to clarify about the 2mm connector – our internal data strongly shows that the 2mm connector is more reliable than the MMCX connector in the long run (partly because it is not allowed to rotate in the socket), so as much as we would like to keep our products compatible with the wide range of accessories available for the MMCX standard, we actually decided to move away from MMCX for our next musicians’ monitors – the MX PRO series.
Instead we will expand our accessory offerings for 2mm cables so customers have more choice (currently we have 5 cable types available). And of course 2mm cables are always going to be less expensive than their MMCX equivalents because the connector itself is so much less complicated.”

What’s in the box:
- M6 PRO In-Ear Monitors
- Cable (2)
- Hard carrying case
- Comply memory foam ear tips
- Silicone ear tips (6 pairs)
- Shirt clips (2)
- ¼” adapter (TRS)
- Transparent casing reveals simple circuitry
- The custom faceplate can elevate the look
- Easy replacement of the cable
The transparent casing of the M6 Pro is an interesting choice. Given that it only has a single dynamic driver, with no complicated circuitry to boast of, the few exposed wires made the driver unit looked cheap.
However, the 2nd Generation of the M6 Pro has a secret weapon. You can purchase custom-engraved faceplates from Mee Audio and paste them on the side of the driver unit. This instantly brings up the classiness of the IEM. I can imagine someone engraving their band name on it.
The M6 Pro uses a 2mm DC connector that plugs into the driver case. There is a marking that dictates the alignment, making the replacement of the cable a breeze. I actually prefer this over MMCX connectors which was a nightmare for me to detach (I always fear that I’m going to break the connector).
- Low profile
- Stiff over-the-ear memory wire
I like that the M6 Pro is low-profile. The flat driver shell (in order to paste the custom faceplate) makes sure that the driver unit doesn’t stick out.
The IEM is lightweight at 20g (including cable) and doesn’t feel bulky in the ears.
Fit is usually not the problem with IEM that is designed to be worn over-the-ear. However, I wish the over-the-ear memory wire had been more moldable. It was a bit tough to wear at first and took some time to get the perfect shape of my ears.
- V-shaped sound signature
- Bass is my favorite frequency
- Background detailing is not strong
The bass is nice and strong enough for me to enjoy EDM songs like Unfinished Sympathy by Massive Attack and Save The World by Swedish House Mafia.
The mids are okay. Nothing to shout about. Despite the stronger bass, I don’t find the mids being muddied by the bass.
The highs work pretty decently for me too. For classical violin songs like Rude by Daniel Jang (my favorite track for testing treble), I find that the M6 Pro round off the highs in a pretty smooth way without making it sound dull.
There are songs where I preferred the background detailing to be stronger. The IEM brings out those details but in a flat kind of way. For me, the sound signature of the Mee Audio M6 Pro is V-shaped. This is my favorite kind of signature when I’m working out.
Overall, I’m satisfied with the sound quality of the M6 Pro. It was within the expectation of what a budget IEM can offer and a little more with it emphasized bass. Among the ~$50 range of IEMs, it is one of the better ones that I have heard so far.

For me, the Mee Audio M6 Pro 2nd Generation is quite a bargain for its extendability.
At this price range, you get to do more things than other IEMs in the same group can offer you.
