I am a fan of value for money (VFM)  products. JBL sells 2 VFM head phones – C100SI and C150SI – they look identical but later is priced Rs.700 more than the other. In a discounted deal, the later is actually cheaper than the former.

The packaging didn’t give me a clue to why one is superior to the other and the online comparisons were very qualitative in nature. So the hunt…

The Harman site lists the following audio specs…

JBL C100SI JBL C150SI
Driver Advanced 9mm driver Advanced 9mm driver
Impedence 16±3.2 ohms 16±3.2 ohms
Frequency Range 20-20kHz 20-20kHz
Maximum SPL 5mW 5mW
Driver Sensitivity 100±3dBSPL, 1mW 100±3dBSPL, 1mW
Rated power input 3mW 3mW
Headphone Jack 3.5mm 3.5mm
Cord Length (m) 1.2M 1.2M

Identical! So I set out to test. Here is a nice post on audiocheck for testing headphones and this is what I found for the C150SI (didn’t have the C100SI model to check, will update when I have access to one.

JBL C100SI JBL C150SI
Frequency Response
     Bass 30Hz
    Treble 16 kHz
Perceptual Sweep Spectral Flatness Good
Dynamic Test 66 dBFS
Bass Shake Rattles  40Hz onwards
Full Range Sweep Good
Wiring Good
Polarity Good
Binaural Test Good

As you can see, there are some issues.  Found good earphones to reproduce Bass as low as 20Hz and Treble as low as 14kHz with way lesser rattle.

Before signing off, on audiocheck, there are a whole range of other tests you can do to check the quality of your audio equipment including your headphones as well.
