I bought it mainly for audio line-in function. I have a 2-player Zune, and there are only two speakers Zune charging stations. Both are very expensive ($ 200.00 Sony ZS H10CP - Boombox - radio / CD and the price of $ 500.00) and are intended for indoor use. I would have rated it 10 if it is USB charging capabilites. I need something for the home numbered / and travel. You can be in any mini-stereo jack. It works with any MP3 player, iPod, Zune, etc. The sound quality is excellent on audio in. Boombox - - I do not have the radio or CD player or Sony ZS H10CP tried radio / CD price since I 5000 + have songs on my Zune. This thing is big, robust, dust-and waterproof. You can not throw it into the lake, but you do not have to worry about rain or spray hose. It also has a faily big compartment that your power supply, audio line-in, MP3 player, rubber stop, etc. I would definitely check it out if you have a Zune. Available at Sears for $ 129.00 plus tax, or Amazon $ 140.00. Now I can share your music anywhere without headphones. My family loves it, my neighbors, not with Sony ZS H10CP - Boombox - radio / CD prices O a lot.
