Definately deep bass, real punchy bass actually but at the same time have good clarity. I like it more than fiio F9. F9 is too bright. But fit and comfort wise, f9/f9 pro is ahead. The fit on F9 reminds me of the way Nuforce HEM series fit in the ear. Ch9t has a wide bore, same as 1more quad. If not wrong, comply size is T-500.
