The Mpow Swift uses Bluetooth 4.0 technology with the aptX codec compression algorithm.
Mpow Swift has “Signal Enhance Technology” which prevents skipping when the earbuds are blocked from the audio source by barriers such as your body. In practice, it seems to work as there are few complaints of skipping or losing signal. Mpow also advertises the Swift has CVC6.0 Digital noise reduction technology which filters outside noise increasing the clarity of calls and music. In practice, it works. Users are very impressed with call quality on both ends, and are amazed at the music playback quality for this price range. The microphone does not have any noise cancellation features.
