The M100, by V-Moda, are spectacular headphones and a must have for any recording or mixing/mastering engineer! They have a killer frequency response, perfect for mixing music and listening to those higher and lower frequencies usually missed. The M100's asre built durable to last and have shown no sign f age since I bought them a year ago! They are also engineered to fit comfortably on your head, which is very helpful when you are investing hours into your music. All and all a fantastic buy and definitely worth getting if you are serious about getting the most out of your headphones!
