Audio Quality

While audio quality is not as refined as more expensive models, the Realtone RT-B16 Wireless Earbuds provide pleasing sound for the price. You get punchy bass and clear mids and highs. Volume levels can go suitably loud. The sound signature is v-shaped with emphasis on bass and treble over midrange. Overall audio is solid for casual listening and calls.
