Summary: After being impressed with the value of the MEElectronics M6 Pro, I wanted to take a look at a bassier IEM from the same company.
The M-Duo is a dual dynamic driver earphone with a separate subwoofer and tweeter unit.
Pros: Ample bass and clarity, No listening fatigue, Good quality construction (and stylish), Amazing customer service, Comfortable for hours
Cons: Cables not detachable, Value eclipsed by their own M6 Pro, No inline volume controls, Not a basshead IEM
Summary: i was a little beginner at the time i used & reviewed this earphone but fortunately enough, i was a Koss user which helped me a lot on this road. i used a lot of earphones after M-Duo and i'm not sure where exactly it stands now, i mean among other similars.
Pros: Hard hitting, deep & powerful bass. Detailed, high quality treble.
Cons: Small sound size and limited acoustic ruins it all.
Conclusion: While the M-Duo’s might not be for everyone, they do provide a fun sound signature that I would recommend to those looking for in the dynamic driver category and they win out over many in this price range.
Pros: Fun sound and value for the price, Great clarity at the top, Dual dynamic drivers, Fun dynamic sound signature with dedicated woofer, Comfortable and non-fatiguing, Plethora of ear tips & carry case
Cons: Slight V-shaped sound signature, Cable microphonics and wind noise, Right angle plug is too large, Flimsy silicone ear tips, No option to buy without in-line control/mic
