Thank you to Joe from MEE for sending these to me to audition, I have really enjoyed the experience. The A151 can be purchase from them from their website or through one of the retailers that carry them. I am going to approach the write up of the review backwards, providing the listening impressions and summary first, then details about the accessories, fit, etc... As I have stated before I am a classical music listener that also listens to other genres on occasion, the equipment used for this review was primarily my rockboxed fuze using VBR -0 files.
From the first day with these I have been very pleased with their sound. They have become my new number one for all genres. The sound is very clear and balanced, They sound great listening to classical but also excel with vocal, acoustic, rock, even drum and bass. They are not bass monsters, the bass is punchy overall they are very balanced and well defined. The cord is a braided dream come true, soft supple, tangle free. Its hard to use anything with a different cord after handling these I listen "with" them rather then "to" them when I listen to classical music. It is easy to get lost in the music rather then reviewing and comparing their sound. I prefer single driver IEM's and only have one pair of dual driver IEMs (UE700). I have many other single driver balance armature phones, I feel these are the best all around pair, a great value for the sound. My only regret is that I wish could have started my journey for the perfect all around pair of IEMS with them rather then ending with the A151. They are at the best of any IEM MEE has put out to date.
What follows are notes that I made while I listened to the listed tracks.
Beethoven Violin Concerto - Hillary Hahn
The separation is excellent, the timpani is very well placed and defined, with just enough presence. Her violin is very present but not in front of anything else. Very enjoyable and detailed.
Attack and decay are excellent on the cello.
Shostakovitch Cello Sonatas
Piano is extra pleasant with these. Plucking of instruments makes me sit up and take notice. Cello is fully bodied and very clear. Details are amazing from the time the cellist starts to draw the bow across the strings to the decay. Texture is smooth. Never fatiguing.
Mozart Sonata for violin and piano no. 18 K301
An amazing balance is heard between the piano and violin. Everything is so evenly matched. Natural. Pleasant. The piano has body, proper timbre. The violin here is sweet, satisfying.
Listening to Electro House
Nice clean sound. bass has good extension, bass does not bleed at all into mids,
Seriously nice tight clean bass, while being able to enjoy all other aspects of the hard hitting electro house mix.
Herbie Hancock quartet
Wow, everything is so well balanced, drums are tight, trumpet is placed well. Separation is awesome, drum solos are punchy never over bearing. everything has its own space. Everything is very balanced and presented together. Compared to my aurvana's, they have a ^ sound sig where the drums disappear behind the trumpet as does the piano. Very engaging lively sound, bright, not veiled not flavored.
Listening to RATM the bass is fast, bass drum has great placement, little minute details are clearly revealed. They are fast, clean, with great separation and instrument placement.

Packaging is their new cardboard box with a clear plastic insert that holds the phones and clamshell case.
Small, Medium, Large, Dual Flange, and Large Tri-flange tips are included. They are pretty standard silicone tips, although I did notice that for the best fit I had to step one size down to medium from my usual large that I wear. The dual flange fit me and were easier to get in and out but did not create an ideal seal. The tri-flange also work very well, however I just don't like the way they look on the IEM's.
Fit and Finish
These are very well built, they are made of plastic but feel very solid. As mentioned in the summary the cable is a huge benefit and a welcome change from what I used to. They are designed to be worn over the ear, they are very comfortable and stay put. The isolation is average and varies a little bit depending on which tips you choose.
