Aftershokz Blues 2S
The AfterShokz Bluez 2S is a recent update to the AfterShokz Bluez 2 model, adding the new “PremiumPitch+” technology, which aims to boost the bottom end and prevent sound leakage, alongside slight changes to the external design. There are now perforated openings where the speakers rest on your cheek, before it was a solid surface. Even with this seemingly more exposed design, the Bluez 2S still meets IP55 standards for dust and sweat protection. The open speaker surface and revamped internals do indeed make a difference in audio quality and volume. It may not be profound, but it’s a noticeable improvement over its predecessor.
