The overall construction is a lot like the Audio Technica ESW9, which a lot of people are familiar with. Due to the bigger housing diameter and the stronger headband clamping force, the ES10 isolates better than the ESW9, while still retaining the same comfortable fit. The cable is still small and soft like the ESW9. I wish Audio Technica would construct a more rugged cable for their portables, as I feel that the soft cable doesn’t inspire a lot of confidence for outdoor use.
I have heard a lot of portable headphone, and I felt that the Sennheiser HD25-1, the Shure SRH-840, and the Audio Technica ESW9 represent the best of portables. As I mentioned in the three-way comparison, each of those portables have their own sound, and each are truly unique in their own way, while offering an overall superb sound. When Audio Technica released the ESW10, it was priced much higher than the ESW9, and though in some areas like soundstage, the ESW10 was better, I felt that the overall improvement is not worth the pricetag, and moreover, ESW10 seems to have lost the tube-like sound that the ESW9 has.
The ES10 is priced close to $600, and that’s a very high pricetag for a foldable, closed, and portable headphone. Yes, you still have the Ultrasone Edition 8 topping the chart at some ~$1500, but the Ultrasone Edition 8 is something of a statement product. Anyway, whether the $600 is a fair price, only you can decide.
