On the first glance, very good! Moreover, I'd say perfect. Repeating, that I'm not audiophile, just love music and I don't try to hear more than I can, I say ES10 is great headphones for portable. Currently, I listen more electronic music and I'm delighted to all of frequencies - from very low bass upto ringing highpass.
Second day. During the day I listen them. During the night I warm them up with "TARA LABS Cascade Noise Burn-In Disc". I especially do not believe in magic, but once there is a physical explanation of the process - let it be. It won't be worse, but it seems to me, the sound became a little more space. Although, perhaps this self-deception.
Convenience is fine. They are tight enough sitting on my head, and it's no excess pressure there. Nor from headband on top of the head, not from embouchures on ears. On rapid walking ES10 don't move back and forth.
Something about "COLD WEATHER". I should say, that these days in Moscow cold enough. To minus 10 degrees Celsius, or plus 14 Fahrenheit, but we never measure in Fahrenheit - I wrote just for fun
I wore them under my hood jacket, and even tried wear them over the fine sport caps. Both options is acceptable - but better avoid both of them under the warm, bright sun, for example, in San-Francisco
Hello to all residents warm places on the globe!
Something about "HOT EARS". By the way, for my topic about UNIVERSAL propeties. Yesterday I listened them at work. All is ok, but it's great ear heaters
Not a big problem, but after some hours your ears will become red and ache a little bit. For listening at home, I still want something other (like Denon AH-D5000 or similar). But, if get used to listen ES10 at work (and home) may be I will refuse from buying other headphones and return to thought to make ES10 universal. That is important to have some mobilty to travel not only street but and inside home. And ES10 with my "old friend" Cowon iAudio 7 - cool combination.
About soundproofing on the subway noise - it's 4 from 5. Little worse than my IEM headphones Sennheiser IE4. But (and this very important!) quality of sound ES10 compare to IE4 is much higher. Bass on IE4 so strong depends from positioning that I had to correct their situation all the time.
ES10 very comfortable, with excellent sound headphones and I think this purchase for $ 350 justified by 100%!
If something will change in this my opinion, I'll tell you, if you want.
