HeadRoom AirHead

Pros: Cheap, powerful, great-sounding, light, small
Cons: None

I have a pair of Sennheiser HD 580's, which are impossible to run off portable CD players well. So the airhead ($179) is a great cheap solution to give them volume and better bass. For a high impedance headphone like the Sennheisers, an amp like the...

Pros: Excellent sound with reasonably efficient phones. Adds bass, clarity and detail.
Cons: Plastic case. Won't adequately drive inefficient headphones.

I originally bought a Headroom Airhead to improve the sound of my Senn HD-497 headphones when used with my portable. I can't adequately describe the improvement. Let's just say that the bass finally has the clean solid punch that had been missing, and...

Pros: Portable, good Amp., AC/DC power source
Cons: Clumsy plastic case. That's all.

I have used my HD580 for 3 weeks and I have been missing what I called a quality sound.

From my tv/vcr, there is no problem in driving this HD 580 with DSP Pro. But, for my portable CD player and my computer, I have used only 1/2 the quality...

Pros: adds clarity, definition, bass and detail to music
Cons: cheaply made

During this past summer I began to get involved with headphone listening as my main source of audio listening. So I decided to purchase some Grado SR60's which by themselves sound great with a portable player. But I kept reading about the headphone amps...

Pros: Portable, nice sound
Cons: Noisy at high levels, inflexible cable

If you have never used a headphone amplifier on the output of your computer or walkman, you are in for a surprise. The Airhead not only gives you higher volume level (very nice in noisy environments such as airplans) but also improves the overall audio...

Pros: Cheap and sounds good. Long battery life.
Cons: Plasticky case.

I never really considered the need for headphone amps-- but then, before this, I also never owned a decent set of headphones. I've been using these with my Sennheiser HD580's, and it sounds amazing, and now I see the point.

A while back,...

Pros: Portable, decent sound quality
Cons: A little too noisy

This is a great amp for portable use, I've used it on many occasion with both my laptop and my Dennon DCP-150 (the worlds greatest portable CD layer) paired with my Sennheiser HD495 headphones. It does what it's basically designed to do, provide...

Pros: Build quality, battery life, portability, increases volume, power, and enhances spatial sound quality
Cons: Not enough of an improvement to warrant the $150 investment.

After my review of the cheaper "Airhead," I ordered the upgrade--the "Total Airhead". I received the Total Airhead (minus the mini-to-mini connector which HeadRoom says they will ship to me, though why bother? I just went out and bought a mini-to-mini f ...
