Is your onboard sound powerful enough to drive your headphones ?

[linuxyogi]

Hi,

I have one wireless headphone which I use to watch movies and the other one

is a corded Logitech headphone. The wireless headphone has its own inbuilt

battery powered amp like all wireless headphone do.

Issue is when I use the Logitech headphone the some is not loud enough to

utilize the full potential of the headphone. Not that its a very costly, high end

product but still when I use it with my mp3 player the sound is much louder

and the frequency response also improves.

One thing I have noticed is if I cross that 100% mark in pulse the output

increases but at the same time the sound gets distorted.

There is not a single brand that makes headphone amps here.

The only option is to import them using Ebay.

The prices are crazy.

256999

So is this a common issue ? Any suggestions ?

Try a Boostaroo (http://www.amazon.com/ThinkGeek-LHSFBA-HC-BOOST1-Boostaroo-Portable-Amplifier/dp/B000219896)?

You can build your own headphone amplifier--there are lots of plans on the web. What is the impedance of the headphones? You can measure the DCR (resistance measured with a DC voltmeter) to get an idea of the impedance. Common values for headphones are 16 ohms, 27 ohms, 32 ohms. It's possible that the headphone out on your computer can only drive higher values. Yes, distortion is a problem if your amplifier is not strong enough.

Read the reviews on your computer. You are probably not the only one having a problem with this specific model.

The item is available on the Amazon.com domain. There's nothing on the .in domain.

I assembled this PC myself. The mainboard is MSI model: K9N6PGM2-V2 (http://us.msi.com/product/mb/K9N6PGM2V2.html#hero-specification).

I have done some amp projects before but not specifically for headphones. Afaik these local amps

are available as a complete product these days so no need to do any kind of soldering but since

these are not branded the quality checking is very poor. So I will take my mp3 player and the

headphones and test the amp before buying it.
