It's not a question of whether you can, it's whether you want to or need to.

solo hd is built for portable rig such as ipod/iphone. so actually it doesnot need an amp to push it. else if you want to have a lil change on the sound signature, then you can couple it with an amp. but i doubt you can hear the change of sound signature, because beats solo hd is not made for details/clarity sound sig, just for fun listening.

or... if you want to boost the bass, then amp will help you with bass control.

for me, it is not worth to get an amp for solo hd. unless you get audiophile grade headphone to couple the amp.

actually it is not useless. if you want extra bass for ur solo, amp with bass boost can help you to get that.

Hafto audition first then you will know if you really need an amp. I'm still looking for my first amp. Choose carefully.

At least for my case, I'm looking for warmer and more bass due to the sharpness/lower bass on my ES7.

Need to do more and more audition.
