HA 4 : Very good for the price

This item does exactly what i says on the tin, I use it for band practices where each instrument is mic'd up and each band member can use this to adjust their own headphone volumes. This product feels very sturdy and will likely last a long time. The knobs also feel to be of a very high quality.

The only disadvantage of this product which should be noted by buyers in the UK is that it comes with a european plug so an adapter must be used for this to work with UK plugs.

Other than this I would definitely recommend it for the price to anyone looking for a headphone amp. I would also be easier if the headphone outputs were small jack plugs as it wouldn't require an adapter for most headphones to be used.
