Great site and awesome headphones

This order was placed and in less than a week I received these headphones. They are great and the sound quality is amazing. I am using them with power amp on a Samsung Galaxy S phone and they work and sound great. About  30 foot range but I can just put the phone in my pants pocket and it works perfect too. I think VMinnovations is a great place and my first buying experience was awesome. They let me know when they shipped and an e-mail when they were delivered. Thanks!

Great price for quality genuine product

It hurts my ears when I used it after 2 hours, otherwise comfortable. I'm a small Asian so I am not sure how it would work for bigger persons. That's why I gave it 4 out of 5.

Absolutely worth the price

I upgraded from a wired Sennheiser 201 set and can attest that the sound quality on these is vastly superior. The difference is subtle but you can definitely hear much more detail. Except for the fact that my set didn't come with the 3.5mm audio cable, I am completely satisfied and it's well worth the price. Also, the headphones fold for easy transport and come with a nice soft case.

Very versatile, but pricey
I love that I can use it for my Android phone for listening to music, calls and even for Skype calls!  Not good noise canceling and a bit tight on the ears, but I seem to be able to get used to it.  Not too bad when walking at the park to prevent falling off with all the motion.  Not great for sitting at the desk all day.  Great carrying pouch, multi-country power adapters and USB power cord that also works with my phone (mini-USB).  The price is very high, but more reasonable for refurbished (I would not call them a steal).  My refurbished unit looks brand new. Overall, I love them, but not perfect.

Sound Quality

The headphones look great and deliver awesome sound from a bluetooth headset. My roomie has beats by dre bluetooth and the sennheisers blow them out of the water in every category except heavy bass but these headphones put out plenty of enough to suffice. With such a crisp, clean and beautiful sound you can't go wrong. My only complaint is that they have cut out on me a few times but it's rare and it generally only happens when I'm using them in the gym. Fantastic purchase and I would buy again from Sennheiser and VMinnovations.

Great price

For the price refurb is a great deal, If I woould of payed retail I don't think I would be as happy. after using it for a few days now I can say that is great for music and ok for phone calls. This is a solid unit, comfortable and easy to use. I own all kind of head phones Beats, Bose, Sony and so on...
