BuyDig is offering the Audio-Technica QuietPoint active noise-cancelling in-ear headphones (model ATH-ANC23BK) for $39.95 with free shipping. Today’s deal is a savings of over 50% off retail, $10 below Amazon, and the best price ever. Perfect for traveling, it reduces up to 90% of ambient noise. Over 280 Amazon reviewers rate it 4 out of 5 stars.
Engineered to create a comfortable listening environment in areas with high ambient noise, these in-ear headphones feature a miniature microphone in each earpiece that picks up ambient noise (such as traffic, air-handling systems, etc.). Electronics in the control box create a noise-cancelling wave that is 180 degrees out of phase with the ambient noise. This wave acts like a noise eraser: it cancels out the annoying sounds that surround you without diminishing the audio you want to hear.
