A warm sound that's great for listening to music
Groove 21 is a Bluetooth-enabled in-ear headphone with two drivers that's perfect for easily listening to music on your cell phone. Enjoy a whole new listening experience with these custom-fit in-ear headphones.
Groove 21 is available as a custom in-ear model.
"Custom" means tailor-made and individually adapted to the ear. The optimum fit in the ear can only be achieved through a personal ear fitting. Nothing offers more wearing comfort than a customized solution. However, this individual fitting not only plays a decisive role in comfort, but also in the sound quality of the headphones. In order to reproduce the bass as intended by the manufacturer, the earpiece must ensure a perfect seal in the ear canal. This is the only way to fully exploit the full sound range, especially in the bass range.
