Some people really don’t like that, so do try the headphone on first. For me personally this isn’t an issue with any of the filters, but they’re very close. Another thing some might find annoying is the driver flex. While normal and completely acceptable, you will experience this when putting the headphones on/off or adjusting them.

This headphone is one that you’ll be using at home or in your office in quiet environments as all the music leaks out and every single noise will crawl in. The ES-2a does need an EST amplifier and those usually are not portable either. The ES-2a comes with a hardwired 2.3m cable, so you do have a good range from your amp.
