Cleer’s ALLY PLUS are a pair of ANC earbuds which have recently dropped in price and come with respectable ANC as well. ANC uses reverse sound waves (analyzed by the microphones in the earbuds) to silence the outside world. The ALLY PLUS aren’t as effective as the Bose QuietComfort or Jabra Elite 85h with its ANC. The outside world isn’t completely shut off but its the best ANC under $200 in an earbud I’ve tried. The battery life is decent, package small, and sound quality good enough to be a solid budget ANC option for many travelers.
