"It is safe to say that FD1 has great value, an ergonomic shape, and good sonic quality for the price. It sounds much better over balanced and if you have a 2.5mm cable, or if you have some adapters from 4.4mm to 2.5mm, you'll have more fun with it, and it will be able to drive harder to get to IEMs and even headphones. The battery consumption is not very high either and it has a warmer, fuller sound that works well for most music styles."
