Koss Porta Pro

to the Porta Pro Wireless. The open construction provides a beautiful spatial sound with fine trebles and voluminous basses. With the Porta Pro Wireless you can hear sounds from the surrounding area so you don't endanger yourself on the road or miss important announcements on the train. Despite the open design, the environment remains virtually undisturbed by your music. The ultra-light and airy design makes the Porta Pro Wireless extremely comfortable. You can barely tell you're wearing headphones. The battery, the Bluetooth unit and the remote control were integrated in the neck cable for this purpose. This also has a positive effect on the sound quality, as every electrical component in the ear cups negatively affects the acoustic performance. The contact pressure of the two handsets can be adjusted to your own needs by means of a slider. The Porta Pro Wireless runs an impressive 12 hours on one battery charge. The headphones can be folded up to save space and stowed compactly in the carrying bag provided.
