Summary: I've purchased my MC5's from Ebay around a year ago (If I remember correctly.)
Since then I've kept them as a backup IEM whenever my main IEM would break on me.
The build quality on these are just fantastic, I've tried recabling one before but I broke one of the drivers on it because my soldering iron was too hot.
But yeah, the build quality is really good, the cable is of average thickness however it is strong.
Summary: These are pretty good IEMs for the average consumer who wants relatively good sound reproduction. This is the first etymotic product I have owned, and overall I feel that they have fantastic isolation and pretty accurate sound reproduction. They are not bass heavy, so if you are looking for something such as that, do not purchase these!
Summary: Etymotic Mc5 vs. Etymotic Hf5
Both are are very ‘true to the ear’ as Etymotic would say... both have amazing tri-flange eartips for superb noise isolation, best in the business actually... and both led me to feel that clarity was an essential part of my music, perhaps even more so than dynamic bass and shiny treble... but in the end, well, lets just save it for the end, shall we?
Fullness of vocals, more bass quantity, slightly recessed.
Summary: (Bear with me, this is my very first review...)
Included in package:
Triple Flange tips, small
Triple Flange tips, normal/medium
Black Foam tips
Replacement Filters (+ Filter replacement tool)
Zippered Carrying Case
Snap-on Cable Clip
Etymotic MC5 earphones
I found these iems fairly uncomfortable; my ears ached moderately after long listening sessions. All tips included never really provided much comfort.
Summary: Sound comparison to the hf5:
Slight increase in bass (may be due to the dynamic driver moving air). Drum kicks and low bass feel more realistic on the mc5, however the bass is of higher quality on the hf5. It's a good compliment if you love Ety's sound with a bit more kick in the bass. And it responds to equalization much much better than the hf5, I could turn this into booming bass monsters with a degree of clarity being remained. Lovely.
Summary: Audio Quality: 1/10
These sound much worse than my cheap Sennheiser cx300s. They manage to suck all life and energy out of any track I listen to. I actually enjoy an analytical and neutral sound signature. These however don't have the detail or sparkle to make up for it's lame frequency response. They just sound thin, small, and dull. There is no fun to be had in the low end. It's there, but it will not make you bob your head or shake your tail feather.
Pros: Fantastic build quality, lots of accessories, good isolation
Cons: Sounds like cold pasta, difficult to fit, very long housing, stock foam tips fell apart
Summary: I received these as a birthday gift and was excited to try them out. The inserts are too large (even the smallest ones) and hurt my ears when in place. Once in the ear, the sound is much weaker than convential ear buds (such as the default units that came with my iPod) and lacks clarity. I made sure that they were inserted far enouogh to block ambient noise, but the sound was still inferior.
Cons: Poor Sound, Too Much Ambient Noise, Uncomfortable
Summary: These have great sound for the price, and of course great isolation. The only thing I'm disappointed with is that they don't fit my Etymotic custom earplugs that work with my ER-6. The nozzle is smaller on the mc5. I'm stuck using the included plugs which are more uncomfortable than my custom-fitted plugs.
