Wireless headphones from H series that offer a pure balanced sound and an amazing comfort thanks to the adjustable headband, flexible design and soft ear cushions. With their 40mm transducers and a frequency range of 20 to 20,000 Hz they provide a perfectly crisp audio experience, with dense bass, bright mids and clear highs. With a battery capacity of 200 mAh, the headphones can last up to eight hours on a single charge and can be used up to eight meters from the source device. Bluetooth 4.0 provides high-quality sound without signal dropouts which is energy saving for both the source and end device.
