Owners of portable media players often complaint about the low volume of their device, when paired with a large headphone. The reason ? these devices are meant to be used with earphones and when paired with larger headphones, the small one just fails to deliver. But like everything else there is a solution, a portable amplifier (If you didn't know such a thing existed, well you know now, thanks to me :) ). Chinese manufacturer FiiO has a range of amps for all your needs, and your wife will approve; they are incredibly cheap and gives your little guy a lot more oomph.
As everything else that is awesome, they are not officially available in India (actually they are, but the distributor sells online and some buyers says stay away from the store, so its up to you); you'll have to get it from the grey market and it would cost you around INR 1000. I particularly like the E-6 (an upgrade of E-5, which had the same design as Apple shuffle), which is small (41mmx40.2mmx9mm), light (just 16g) and gets the job done. It is powered by a built-in lithium battery, so you don't have to worry about powering this unit using a heavy battery. Here are the specs (if you understand all the numbers) :
- Output power:150mW (16Ω Loaded);16mW (300Ω Loaded)
- SNR:≥95dB(A weight)
- Distortion:<0.009%(10mW)
- Frequency response:10Hz~100KHz
- Headset impedance:16Ω~300Ω
- USB power supply port:DC 5V/500mA
- Power supply mode :Built-in rechargeable lithium battery.
- Size:41mmx40.2mmx9mm
- Weight:16g
