Walmart offers the Philips Bluetooth Noise-Canceling Headphones, model no. SHB8750NC, for $39. Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with our mention from a week ago and the lowest price we could find now by $16. They feature a frequency response of 10Hz to 22kHz, Bluetooth 4.0, and up to 16 hours of music playback.
