A:Answer They would hold up well, but you should consider the Sennheiser HD280s. They also are pro monitor headphones, they sound almost identical to the HD380s, seem to be built even more sturdily, and are about $100 less! I have both, and the difference in sound between them is so small that it took extensive listening and instant switching between them to hear any difference between them, and it was so subtle that I could write the same review about either of them. Only when your music goes to the very bottom of hearing are the 380s only slightly more solid. You will hear no difference on 99.48% of all music.
As to sound, the Beats phones sound artificially boosted somewhat in the midbass, where the Sennheisers may not be quite as strong, but are a more accurate reproduction of the recording. Listen to both, and decide for yourself. Trust your ears.
