I use the Sennheiser HD-485 for a week now and am quite happy with this model. What I like most about this model is the sound reproduction (I find pleasure Technology circum-aural) and the design ...
The peculiarities of this model are:
<ul> Impedance: 32 Ohms
Frequency response: 16 Hz to 24.5 kHz
Sound pressure level: 110 dB (SPL)
Total harmonic distortion: less than 0.2%
Connector: 3.5 mm stereo jack with adapter 6.35 mm
Weight: 220 g
Cable: unilateral OFC strands 4, 3 m
</ul>
I purchased this model mainly for its quality sound reproduction (bass present, deep sana excess, medium and treble correct and clear) and its low impedance (I use a Hi-MD Walkman) ...
Compared to my old Sony CD250 headphones, there's really no comparison!
The quality / price is acceptable (bought new for 72 €) yet if the sales team at Sennheiser and my dealer could make it less pockets, it would be better for sure ...
With the experience I remake this choice largely!
