beats solo are cheaper and they can break easily while solo hds have a stronger headband and they have much clearer sound too
yes
Beats by dr.dre solo hd is better than studio its portable lightweight nice quality
None. solo hd doesn't snap that easily but i'm not saying that they won't break but the solo breaks very easily Beats solo suck even the hd get studios or pros if not enough money to buy them then save up the money until you get enough to buy the pros
The solos have a matte finish, the solo hd has a shiny finish The solos have much better bass, but the solo hd has clearer sound so you can hear the mids and highs the solos are cheaper than the solo hd
