Boltune's over-ear Bluetooth headphones have dropped to $39 on Amazon

Boltune's active noise-cancelling Bluetooth over-ear headphones have dropped to $38.99 on Amazon. That deal price is thanks to a combination of a $10 off on-page coupon and the code DBGFTDHT, which applies another $11 discount during checkout. The headphones normally sell for $60, and today's drop matches the lowest we have ever seen.

They use hybrid active noise-cancelling tech, deep bass with 45mm large-aperture drivers, and protein ear pads for extended comfort. They also have a built-in mic so you can take phone calls with its own noise-cancelling for vocal clarity.

Boltune just upgraded these headphones with some new and improved technology. The hybrid active noise-cancelling tech can reduce external noise by up to 96%. And really, is there any noise that matters except for the noise you want to listen to in the form of your favorite music or podcasts or whatever? Block out the sound of traffic or the sound of the subway on your way to work. Focus your mind while you work and tune out the gossip and clicky clack of co-workers' keyboards.

You'll also get high-quality sound with neodymium magnet drivers that provide impressive bass and authentic music. The protein ear pads are so comfortable it's like a pillow on your head. You'll be able to wear these for hours. And the rest is made with a high-tech aluminum alloy material. The headband is rotatable and durable so you can find the perfect fit.

Use the headphones to answer phone calls, too. They have built-in mics that use CVC 6.0 technology for their own noise-cancelling that helps keep your voice clear and sounding great while you talk. You can essentially go hands free while you keep the conversation going.

It's a good thing these are comfortable enough to last for hours because the battery can go for up to 30 hours. They only take one hour to charge, and the fast charge can give you up to two hours of play after just five minutes. You get a two-year warranty, too.
