Pros: Very clean, Clear, transparant sound, better improved high end response. Great detail
Cons: Had some fit issues, had to send them back twice, but now good
I had owned the UE-10's before this for about 3 years. So upgrading to these was a huge improvement in my opinion. Very nice full sound, with improved frequency response from 20 Hz to 18,000 Hz. Bass is much more present on these but not too overly stated. Gorgeous build quality. Very happy with these In ear monitors, I also own the JH-16's and still love listening to these all the time on the go.
