Then 10 mm titanium drivers were added to accentuate their performance.

Virtual Hybrid Noise Cancellation detects and virtually eliminates background noise such as automobile traffic and airplane engines by up to 30 dB to allow you to focus on what's important. Engineered with Feed Forward technology, these earbuds use an algorithm on the back end to convert to full Virtual Hybrid Noise Cancelling Headphones.

The charging case provides an additional 420 mAh of charging power to allow for a combined usage time of over 40 hours.
