Good sound but lacks power

These HP works well on my iMac but the advertised power is in my opinion a bit on estimated.
I once had a Harman Kardon amplifier (2x20) and I had a much higher volume ... This is not a worry to me
precisely because I changed the amp because it was too powerful (to 11m2).
But some may be disappointed if they expect to have real watts :)

Another little problem, they are not isolated and if I place my phone close it sizzles.
The off button on the back is not too convenient.

Apart from that, she is very beautiful and take up less room than I thought, the sound is good (at my level) and perfectly adequate for sound to my room of 11m2.

A note to Amazon:
The speakers were delivered in the original box which had been opened and re taped by Amazon.
No cardboard 'anonymous' only protected the whole. In this case Amazon should warn that the product is not necessarily 'new' but re-conditioning.
