I was looking for a speaker system for my ipod mini for an upcoming holiday, and I bought this item on the strength of the reviews I read here. I was not dissapointed either!! - it's quite remarkable how much power this unit can generate. The clarity is very, very good, and although the bass end is obviously not the beefiest (compared to a proper hifi unit) it does deliver a good punch, and the bass is still very evident, and retains very good solidity.
The volume controls are very easy to use, and I can't quite understand any complaints about them - you simply tap on them repeatedly to incrementally change the level up or down. The unit is solid, and a little heavier than i anticipated, but that can only helps the bass end I think, and there are no rattles when playing at high volumes, and let me tell you, this can really kick it out, but realistically, you'd probably only use it at half to 3/4 volume for a more than adequate volume for most uses.
Sound quality is retained at lower volumes also. The stereo image is adequate - the speakers are only 6" apart afterall!
I have noticed the same hiss that someone else mentioned (either on this or the white version), but have also noticed this is only when the screen on my mini dims! - I set it to not go off, and there is no hiss at all! - a quirk to be sure, but not enough for me to send it back, since it scores highly in all other aspects.
If you want a true hi-fi sound, then spend a few hundred on a hi-fi with big speakers and a quality amplifier, but if you want portability and power for your ipod, I think you'd be hard pressed to find a solution with comparable quality as cheap, and in fact, I have heard less quality from some hi-fi units to be honest.
Because of that small niggle on the hiss/screen dim, I would have given this item 4.5 stars, but given the value for money and overall high quality of the unit, it gets 5 from me!
Now - I wonder how many of these I could justify throughout the house.... ;)
