FREESTYLE FH0917 are wireless headphones with Bluetooth 4.2 technology and built-in microphone.DESIGNED FOR YOUBlack, red, white or blue? Which color do you choose? The FREESTYLE FH0917 wireless headphones are available in four different colors, so you can easily choose the variant that suits you best. We covered the outer part of the shell with a reflective coating in the same way as a CD, while the headband was made from a combination of plastic and gummed material, which makes it even better on the head.SOUND IS THE MOST IMPORTANTFREESTYLE FH0917 are equipped with powerful transducers that generate a frequency response from 20 Hz to 20 kHz with balanced acoustics and clear sound. Headphones work well with all genres of music.RELIABLE BLUETOOTH TECHNOLOGYWireless connectivity will let you free yourself from cables and use headphones more comfortably than ever before. The Bluetooth 4.2 standard also means faster data transfer, greater energy savings and even better security. A device connected wirelessly to the headphones can be located at a distance of up to 10 meters from it - it's convenient especially when you are at home, and your smartphone is on the desk connected to the charger.HEADPHONES WITH A LOT OF ENERGYIn the FREESTYLE FH0917 model we used a battery with a capacity of 450 mAh, which will allow 100 hours of work in standby mode. If you decide to listen to discography of your favorite artist, the headphones will allow you 10 hours of continuous music playback. It's a lot, compared to how fast it takes to charge - just 2 hours. We used a standard MicroUSB connector in headphones, so you can charge them on the go with a powerbank.HEADPHONES FOR YOUR SMARTPHONEThe FREESTYLE FH0917 headphones have a built-in microphone and music control buttons - volume control, song rewinding, pause and the ability to receive phone calls.
