These headphones are made by Denon, a company which I had never heard of in my life, but a friend recommended me to them, so I borrowed these headphones. Firstly, the design of these are pretty generic, one of about a thousand that look exactly the same as it. So I wasn't expecting much. Then I tried them on many different types of audio. I was impressed by every kind. My first choice was a classical piece (this tests all kinds of dynamics and pitches)- I was amazed by the superb depth of the music flowing through my ears. I then proceeded to a spoken word track- this was also impressive; the words were perfectly clear and, unlike many headphones, the treble balance was great. Pop music was another strong point, although a tiny proportion did sound a tiny bit tinny (and I know the tracks to not be tinny themselves) Sound isolation, too, was good, although it isn't mentioned in the description, I could barely hear anything but the music. The volume is also great, there is no need to worry about these phones not being loud enough, they can go to a deafening sound! Overall, these lightweight, mid-priced headphones are a great buy for those who want good quality sound for their music player.
For music listening on-the-go as well as private listening at home, the AH-D1001 features Denon's exclusive Microfiber diaphragm technology, with an ultra lightweight radiating surface that provides a frequency range that extends well above the range of human hearing for crystalline clarity. To eliminate the colorations caused by sealed-back enclosures, the AH-D1001 also features Denon's acoustic optimizer design, for the most natural, uncolored sound quality. The adjustable headband features comfortable ear cushions with soft internal padding, while the over-the-ear design provides comfortable isolation from outside sounds, and the unit's light weight ensures fatigue-free listening. For on-the-go listening, the AH-D1001 comes with a 1.5 meters audiophile grade OFC oxygen-free copper cable featuring equal length L/R cable design, along with a convenient carrying pouch. For home listening, a 3.5 meters extension cable is also provided, extending the total cable length to a full 6 meters (19.7 feet).
