The RHA MA650a in-ear earbuds allow you to listen to HiFi sound. The special drivers have a frequency range of 16 to 40,000Hz, which means you can clearly hear every musical detail. Thanks to the closed design, the music sounds natural, without distortion. To wear the earbuds, you place the cable over your ear cup, ensuring they stay firmly put. You can use the controls in the cable to switch between tracks. These can also be used to adjust the volume. The integrated microphone allows you to make hands-free calls. The control in the cable is optimized for Android and doesn't fully function on Apple products.
