Cowin’s noise-canceling over ear Bluetooth headphones were a top seller on Kinja Deals even before a price mistake that pushed them down to about $10 for one glorious morning, though that sale truly pushed them into the stratosphere.

Once frequently available for around $40, the Cowin E7s are comfortable, run for up to 30 hours on a charge, and most notably of all, include active noise cancelation. The feature doesn’t work as well as what you’d find on wares from Sony or Bose, but they perform respectably for the price.

This year, Cowin updated the E7s with a new Pro model, which includes larger drivers and premium finishes.
