Yes if you are the guy who likes style. No if you take sound seriously.
Beats Solo, Beats Solo HD, Beats Tour, iBeats, urBeats, HeartBeats, PowerBeats, Beats Mixr, and Beats Pro
beats solo are cheaper and they can break easily while solo hds have a stronger headband and they have much clearer sound too
The power from the device your headphones are plugged into powers Beats Solo HD's.
Beats by dr.dre solo hd is better than studio its portable lightweight nice quality
but evn if it isn't wireless the sound beats all. it worth your money
No, Beats by Dr. Dre Solo headphones do not require batteries.
the beats solo
No, Beats Solo and Beats Mixr don't.
Yes!
3-20,000
yes
Beat pro are definitively worth it if you are looking to become a audio engineer or dj, but if you just want good sounding headphones for daily use, get the solo hd. Cheaper... I personally have beats pro and they are very good... not the best headphones out there but thats my opinion as i am a professional DJ.
