Koss Launches Porta Pro Limited Edition in Two New Colorways

Koss Corporation, the U.S. based high-fidelity Stereophone manufacturer and inventor of the world’s first SP3 Stereophone in 1958, announced the release of its Porta Pro Limited Edition headphones in two colorways, which were both chosen by Koss fans worldwide. Two Porta Pro Limited Edition designs are now available exclusively on the company’s website. The new Koss models maintain the essential of the popular over-ear design, with some additional features.

The Sennheiser HD 800 over-ear circum-aural headphones are cherished by music lovers throughout the world for its brilliant sound image and impressive spatiality. With the HD 800 S, the German brand now presents a new version, which surpasses the listening experience of its predecessor. The HD 800 S features the same proven large dynamic transducer technology, now with an optimized medium and low frequency response.

Blue decided to follow-up on the positive things achieved with its original Mo-Fi headphones and has now introduced Lola, dropping the built-in amplifier while maintaining the main positive things from its radical form-fit design. Lola shares the same custom 50mm drivers in a new lighter, slimmer design that actually allows enjoyment in comfort.

Offering closed-back performance and open-back sound for monitoring, mixing and mastering, AKG introduced at the 2015 NAMM Show its K553 PRO closed-back studio headphones. Available only in the USA, the K553 PRO’s provides an optimal balance of noise-isolating qualities of closed-back headphones and the spacious, multi-dimensional sound of an open-back design.

“We weren’t going to replace the QC15 headphones unless we had something that was better and different - and the QC25 is both.” That’s how Bose introduced its QuietComfort 25 Acoustic Noise Cancelling headphones, combining an entirely new design, greater portability, better noise reduction and audio performance.
