Summary: what there is to say ? soundstage ruins it all. it has nearly the same soundstage with the already trash earphones like the brainwavz m4, xiaomi piston etc. the bass is really there but i've to say, 125-250-500hz frequencies comes overly amplified, still not as koss kdx100 but it is enough to give one a headache.
Pros: Crystal clear highs, Above average bass
Cons: Bass acoustic is not big along with the soundstage
Summary: MEElectronics customer service was a pleasure to deal with. I told them about my old ear buds, still under warranty, and all I had to do was cut up the old pair, take a photo with a hand written note, and they sent me out this as a replacement. All done through email when I had the time. Couldn't be happier!
Pros: I received these as a replacement for another older model that is now discontinued and ultimately failed. All the negatives from the older model are wonderfully absent in this one. I've said it before, I'm no audiophile, but it sounds like these other reviewers are, and if they are happy with them, then I'm over the moon!
Cons: In the few months I've been using these, nothing yet.
Inexpensive headphone that outperforms many more expensive counterparts.
Harry L., Newegg
5 June 2014
Summary: While listening to some harsh techno I noticed slight bits of sibilance, but after 12 hours of burn-in with a pink noise FLAC on repeat, it has become unnoticeable.
Pros: It takes a full advantage of the dual driver design, and produces deep, punchy, yet well-controlled bass while excels in high notes like some balanced-armature headphones do. The sound stage is slightly v-shaped, as the mid may sound a bit subdued, but I find it rather fun to listen to.
Cons: Ear tips need some improvement. Those translucent tips quickly become slippery and easy slip out of my ears after hours of use. Replacing them with the double-flanged tips (included with the purchase) remedied the slipping issue, but they aren't as comfortable as the single-flanged tips.
MEElectronics M-Duo Dual Dynamic Driver In-Ear Headphone with Inline Microphone and Remote
30 December 2013
Summary: These are simply incredible earphones. The dual drivers provide not only amazingly powerful and extended bass, but real detail and clarity to your music as well. They rival the very best IEMs out there, but at a much cheaper price.
Summary: I received these headphones a month ago and am extremely pleased with them. First off, as soon as you place them in your ears, they are comfortable to someone who has had problems getting earbuds in the past. Once you plug them in, the true pleasurable sound experience begins. The sound quality is amazing on these headphones.
Summary: The Meelectronics M-Duo is the newest addition to their Signature series of in-ear headphones. Its dual dynamic drivers boast strong and well-extended bass, including a separate woofer and tweeter. I bought the M-Duo directly from Meelec and was pleased to see it did not skimp on packaging or accessories. Accessories include a redesigned hard clamshell case, shirt clip, and 6 sets of tips in various lengths and sizes. The tips are soft and of pretty high quality.
Pros: -Sound- The M-Duo fits right in as a flagship addition to the M-Series, offering a fun, yet only mildly V-shaped sound. These IEMs are far from neutral or analytical. The first thing anyone will notice upon listening to the M-Duo is the earthshaking subbass response, which enjoys a powerful boost along with the entire bass range. The result is a dominant and fully extended bottom end that remains well controlled. The bass may lag behind armature models in speed but ma...
Cons: - Remote/mic position hindered when worn over the ear - Mild driver flex - Average Isolation (need to blast away louder noises) - Longer tips may be uncomfortable - Soundstage wide but lacking in depth - No version without remote/mic (for some a Con)
Pros: When I first received my M-Duo, and opened the upscale packaging, the construction of the M-Duo really impressed me. The headphone itself is all metal construction, with a built in microphone/control switch on the cable. The headphone jack has a unique right angle designe..very easy to insert and remove from whatever device you might be using. The cable itself is supple, and I noticed almost no microphonics (annoying rustling and thumping noise when the cord brushes u...
Great IEM for the money, build quality needs attention
Tymen Jissink, Amazon

Summary: One of the best IEMs you can buy for the money. I actually prefer these over the Nuforce Ne-700X. Both have been tested with Comply T400 tips (a must, in my opinion). Unfortunately, the M Duo's left in-ear stopped working. Within just two months of very light usage. Very dissapointed with the build quality of these things, as it is probably a faulty cable. Anwyays, this is not supposed to happen so quickly!
