Nop, with all due respect that's incorrect.   The High socket has at least 50% more gain that the low one.    With my JH16's I can handle the volume up to 60% ( 1:00 o'clock ) when on low output but once connected to high output I can't bear the loudness beyond 40% ( 10 o'clock )

Quote:   JHA recommends that you fully open your mouth to avoid breaking the seal with jaw movement.   Most of the Audiologist don't find it necessary though.

Quote:   And that's because ?  ( why , how come, what genre do you listen to, what's your setup and what are you comparing these to ) 

Quote:   Yeah but I don't have an Iphone . Would that be an issue? From what they wrote " made for iPod/iPhone "

Out of curiosity , the Low headphones output on the D100 means it has high impedance and vice versa ?    Correct me if I'm wrong.

Also something I never mentioned, it depends on the listening volumes. I listen most of the time at really loud volumes.   If you try the test track "Stereophile 40 Hz or 31.5 Hz, one third octive warble tone at -20dB" , you can never feel the bass at low volumes unless you have an amp. From...

Quote:   I think it all depends on what your ears are used to. Shure 530/535 are brighter than the 16's. The 16's are brighter than the 8A in my opinion.

Quote:   They are only bright if I break the seal. Once they are in it's another story. The sound signature is more like L shape instead of V. You know that feeling when the first octave note on the piano rattles your ears because of the bass... Something I never experienced with other...

Quote:     I spent another 2 days with my Shure SE535 and went back to the JH16's. I found the 16's way too warm. I think it's not the burn-in but my ears getting used to the sound.   I'm starting to believe that it's all in my head.

Quote:   Well I must admit that it was a quite fast judgement and review. Not sure what could have changed in the next day you listened to your 16s. Burn-in needs hundreds of hours.

Well yeah the JH16's bass is unbeatable period.   I spent my night with some audio freaks friends and played with the Shure530/535 Westone4, Beats by Dre, Senn IE8, Q-jays and Ath-ck10...   No No No... seriously I amped them all with my Yulong D100 MK2 Dac/Amp and the JH16's literally...

Quote:   I mean you're not coming from tier-A IEM or anywhere close. It literally took me months to get used to the JH16 sound signature. My first impression was like yours but it lasted weeks.   I spent a lot of time matching impedances, changing cables, DACs and Amps to find my...
