Description


German Maestro Studio Series

Introducing the GMP 8.300 D Professional Pro stereo headphones, the professional headphones in the Studio Series from German Maestro. Each pair of these revolutionary headphones are designed to meet the highest demands and standards that the German Maestro name represents. With a long history of sound research and speaker engineering, the company has released the GMP GMP 8.300 D Professional high performance headphones. They represent the highest headphone technology and exhibit the most advanced acoustic reproduction. With emphasis on clean accurate sound, these headphone offer the highest efficiency and impressive bass performance. The trebles are crystal clear, the mid-range emphasizes each and every rich detail, and the bass reproduction is quite dynamic. They are made from durable materials (included unbreakable steel) that ensure the headphones last many years. The soft synthetic leather ear pads ensure a perfect fit and an excellent comfort level for each and every time you put the head phones on your head. The user can wear the headphones for hours on end without any discomfort or ear ache. Unlike some of the other German Maestro headphones, these feature a single entry cable attachment that allows the cable to connect to the headphones on only one side. The cables themselves are highly flexible and include an additional extension cord. The simple design of the headphone allows it to sit comfortably on the ears. For the professional music listener that demands a tough, durable pair of headphones, choose the GMP 8.300 D Professional headphones!
