Pros: Excellent comfort, cable and build quality, good sound quality overall
Cons: Bass-slanted and warm sound, slight veil, over-the-ear only, too "fat" timbre, possible fit issues for people with small ears
Bass is slightly boosted with a bit of extra warmth thrown in, but nowhere near the amount present in IE8.
Mids sound a bit aggresive with some 3.5k boost.
Highs are present, though not exactly delicate. Some 6k hump exists. Extension is ok, but the highest lack volume.
In general, the response is bass oriented, which is easy to correct with an equalizer. Timbre is a bit fat on this one. Not smooth, but a kind of "substantial", heavy-handed sound with not a lot of microdetail.
Comfort is excellent.
Isolation is mediocre - the vented design and shallow fit take its toll.
A decent set of tips is included in the package - single flange, biflange of 3 sizes and smallish olives. Cable is perfect, thick, tangle free and supple, with high quality straight 3.5mm jack, zero microphonics. Both ends are well strain-relieved.
Soundstage is huge and pretty far away, but intimacy is correctly rendered. Positioning precision could be better.
If not for the heavy handed detailing, these could be called an older brother of VSonic GR07. Sound signature is similar, with more bass emphasis and definitely no sibilance in the Sennheisers, but some slight veil.
