These are the real deal! My buddy and I ordered different ones, I ordered these and he ordered the beyerdynamic ones that I think are more than twice the price. I like beyerdynamic but apparently those clips are very good for other microphones.
These on the other hand won the battle, I couldn't be happier with them, they're cheaper than the sennheiser equivalent too! and they're good ones. These are more or less exactly the same as them. Absolutely brilliant!
They've even got the little XLR cable holder to make it a nicer job, couldn't get any better than that. Saves a load of trouble buying more mic stands and will save you a load of money (and more importantly time)
