headphone amplifier

[raymondgh]

Hi,
I have bought a headphone it's a low impedance (32) one with high sensitive (108) but comes with great power (2200mW)
do you think an amplifier would derive it better?
here's a link to it.

I usually listen to music with my macbook pro or Nokia phone

for macbook:

Jack type: 3.5 mm stereo
Maximum output voltage: 2 VRMS (+8.24 dBu)
Output impedance: < 24 &#937;
Frequency response: 20 Hz to 20 kHz, +0.5 dB/-3 dB
Signal-to-noise ratio (SNR): > 90 dB
Total harmonic distortion + noise (THD+N): < -80 dB (0.01%)
Channel separation: > 75 dB

Are you asking if an amplifier would help when using your phones with your Macbook and phone?

If your phones have the right plug to work with them, you can test it by plugging them in. Does it play loud and clearly enough? If not, then an amp may help.

The best way to find out would be to take your devices and phones to a store that sells such amps and ask if they will demonstrate the models they have in stock. If it sounds better, you'll know, and you'll know what it costs.

If you know something about building electronics circuits, and you're ambitious, you could build a very good one for probably under $20 in parts that would run on 2 x 9 volt batteries or a little more if you wanted to run it from a wall wart.

If that interests you, I'll see if I can dig up my schematics for one I designed a few years ago.
