Wildomar, Calif. - (January 8, 2010) – Ultrasone Inc., distributor for German headphone manufacturer Ultrasone AG, announces the delivery of its flagship HFI Series headphone – the HFI-2400.

The HFI-2400 is the newest top of the line for the HFI family that stands for excellent, high fidelity sound reproduction. To do this, Ultrasone developed a gold-plated 40mm transducer that, by means of its decentralized placement, presents a more realistic and spatial sound production. With a frequency response of 10 hertz to 25 kilohertz, the HFI-2400 comprises more than the spectrum of human hearing and assures that all of the frequencies in a recording are correctly reproduced. Melodiously, Ultrasone has aimed for a dynamic and detailed sound with brilliant trebles and despite being an open-back headphone, boasts thunderous bass.

The decentralized placement of the drivers guarantees a previously unrealized three-dimensional sound. For utmost comfort, Ultrasone has chosen a high quality, soft padding for the ears and the top of the head. Weighing in at only 292 grams, (just over 10 ounces), long music sessions turn into pure pleasure. The HFI-2400 is especially outfitted with mu-metal shielding that reduces the electro-magnetic emissions up to 98% compared to other headphones on the market. This patented technology to reduce electro-smog is unique.

V-Moda M-80 Headphones Announced

I recently reviewed the new on-the-ear Headphones by V-Moda called the True Blood V-80 Headphones. Now V-Moda is re-releasing the same headphones to the non-True Blood believers called the M-80 Headphones. These headphones are excellent in almost every way and I even kept a set for myself. The pricetag will be $230 (which is the same as the V-80's), but they are worth every penny as they have superior sound quality and they are extremely durable. I won't be getting another set of these headphones as we already reviewed them via full video review, but these are basically the same headphones without all of the True blood product branding.
