I actually just got my pair of JH16's last week Thursday (today is day 8). I've probably listened to them for at least 4 hours each day, more on the previous weekend. So I have about 30-40 hours of use.
So far, I am not very happy with my purchase. I am holding out to make my final opinion until I get my desktop headphone amp (I currently only have two DAP's to use: Sony NWZA818 and clip+). I find the JH16's to be very, very sibilant. In fact I didn't really know what sibilance sounded like until I listened to these... My TF10's don't sound like this at all. When I fired up some tracks from my favorite artist, Seal, the sibilance in the song "Free" in his album "Soul" is just downright painful to listen to.
As far as the seal of the headphones go, I think it is perfect on the right headphone, but I will need to send the left headphone back for a refit (if i am not careful and move my jaw the seal is broken and I can only guarantee a perfect seal by applying ever-so-slight pressure on the top of the headphone). Even when I apply the constant pressure and have a good long listen I am dissatisfied with the results. It has been 5 months since I have been able to listen to my HD650's with amp (i get them back tomorrow - i moved a few months ago to Eruope). But I know Seal's albums very well and I just do not remember them sounding this badly. I can't say that there is a lack of detail, but I wouldn't say that the details presented by the JH16's is any better than my TF10's... which absolutely should NOT be the case. The JH16's should blow the TF10's out of the water.
The bass isn't nearly as punchy as everyone has alluded to. I have heard it called "visceral" upon multiple occasions. I do not find it so at all. I prefer the bass of the TF10's. Is there bass? Absolutely, but to my ears, its more boomy than punchy. Sure there is some punch in there at times, but not what i was expecting and I do think the TF10's are better in this area as well. Because it seems sort of boomy at times I am thinking that perhaps my DAPs just aren't up to the job without an amp (yes i know an amp will help regardless) but it was my assumption that the JH16's would work fine without an amp and would work just fine alone with a DAP.
As far as source material goes, I listen to solely FLAC on my clip+. I only have VBR-mp3's on my Sony DAP, i think they are about ~215 bitrate, which shouldn't be too much worse than 320 FBR.
Right now I'm feeling like my particular pair of JH16's is worth... I don't know... $250? But in light of the fact that TF10's can be commonly purchased for ~$100... I just don't know. I'm going to keep using my JH16's and talk to JHAudio on Monday... but right now I definitely prefer my TF10's. /Sigh
On a lighter note, I am a HUGE fan of the stock silver (clear) cable that came with the JH16's! It is very supple, smooth, and looks sharp. Now if only I could be half as happy with my headphones as I am with the cable!
So... WTF is going on? Any ideas guys?
