The Harman site lists the following audio specs…
|JBL T110I||JBL C100SI||JBL C150SI|
|Driver||9mm driver||Advanced 9mm driver||Advanced 9mm driver|
|Impedence||16±3.2 ohms||16±3.2 ohms|
|Driver Sensitivity||100±3dBSPL, 1mW||100±3dBSPL, 1mW|
|Rated power input||3mW||3mW|
|Cord Length (m)||1.2M||1.2M||1.2M|
Not much right. So, here are the audiocheck results.
|JBL T110I||JBL C150SI|
|Perceptual Sweep Spectral Flatness||Good||Good|
|Dynamic Test||72 dBFS||66 dBFS|
|Bass Shake||Rattles 40Hz onwards|
|Full Range Sweep||Good||Good|
As you can see from the above, T110I one is slightly better than C150SI in terms of bass frequency response and noise isolation. It also feels snug in the ear and doesn’t hurt the earlobes on prolonged wear unlike the C150SI which is bent at a very odd angle and can hurt sometimes.
