- Sound quality is superb, the attention to detail is astounding, the build quality is superb, you can hardly hear anything outside when you put them on, the bass is strong, the soundstage is wide, there is no background noise, the ear cushions are soft and replaceable, the wire is flexible, the case is included, and I personally like the straightforward design.
- Because of the slightly elevated peaks, I had to use an equalizer to tone them down; this is a positive; the bow presses too hard; I had to straighten it out; the case can be arranged more impressively; the soundproofing fee is still not ventilated; the ears sweat somewhat; however, this is less of an issue than with earlier models of Zenheiser headphones. After two years, I discovered a flaw: the right ear had ceased functioning. However, if you pulled the wire near the headphone cup, the sound returned. I plan to solder, as I later found my native cable to be priced at $2,500. Once the fix is complete, I'll update.
