We chose these Bluetooth earbuds based on three factors: functionality, sound quality, and price.
Some of these earbuds are low cost and have fewer features than higher cost models. However, for the price, the sound quality was excellent, and playing time and charging capability was good.
Some of the earbuds have extra features such as the ability to adjust the volume in the ear buds and to modify the active noise cancelling settings. The Coumi Fiil CC2 earbuds have an app to adjust the sound settings, while the Soundliberty Pro 10 have a feature that detects when they are removed from the ear and will pause the music. This entire range of earbuds has little distortion -- even with the cheaper models.
If price is not an issue, then the Soul Emotion earbuds are certainly worth a try -- especially if you like an immersive experience when listening to music.
