I got to hear both the UE 10/11s and JH 10/11/13s at CanJam. I'm really not up to speed on the latest IEMs, I'm still using my ER6is. I really wasn't planning on getting a new IEM but after hearing these I think I might be.
I listed to each phone out of my Zune directly w/o any amp. I listed to each phone at least 2 seperate times, going back an forth between the two tables.
First, the UE 10s really underwhelmed me. They seemed very muddy for the price. The UE11s were much better. Clear, neutral, good bass. Not a bad phone at all, especially for the CanJam price of 25% off and free impressions.
Now the JH IEMs I felt were in a completely different league. Jerry said he's spent considerable time fine tuning the designs since leaving UE to get them exactly how he wants them to sound and I think it shows. The JH10x3Pro immediately blew me away. Head and shoulders above the UE10 and possibly as good or better than the UE11. Of all the IEM they had the brightess presentation while still having decent bass and good details/clarity. The JH 11/13s I found to be very similar. Both much more neutral than the JH10x3s with slightly better bass. Maybe a little more clarity as well. Overall I preferred the JH10x3s because they sounded a bit more lively. JH Audio is offering a CanJam price of 10% off although no free impressions. Since his prices are lower than UE for the same offerings, I think I'm going to go with the JH10x3s.
