Very powerful

Nice looking and very powerful. I'm very happy with the choice i made.

Good but...

The sound on this music system is great: it can go very loud indeed. However the 3 speakers are huge and take up too much space, so it's not really a mini hifi system. Haven't tried the other features yet.


Good speaker love it good good good loud chill man and

excellent looks and great sound.

This is an excellent Hi-Fi System with great looks and excellent sound system. Good value for the price paid.

Clear, crisp sound in an awesome display

What I love most about this Hi Fi System is how clear the sound is. There is no distortion, no matter how loud you play it. The Hi Fi is in constant use and being able to connect via Bluetooth has meant my phone is no longer having to remain connected. I can walk around the house and play whatever song I fancy. The KaraokeStar is a great feature, the inner popstar in me has been released!

Powerful Hi-Fi system to get the party going

I've got this and didn't know I would have got so many compliments about it. All my friends want to know where I've got it from. It's amazing for a party and the volume goes high with no distortion of the sound. I had a BBQ last week and I was conscious of the disturbing the neighbours, It really bounces and got all my guest buzzing. The Auto DJ is pretty cool, I had an old CD with some 80's hit and with the feature, it blended all the songs in perfectly as those I was standing over a turntable mixing tracks. It allows me to connect my phone and play my music as well. It's worth every penny and it looks good on my table as well.
