For the true audio enthusiast, there's a lot of difference between putting on some songs "for background music" and a true listening experience. For the latter, there's nothing like a pair of sturdy headphones and the powerful speakers that come with them. And the wireless variety doesn't get much more powerful than the TREBLAB Z2 Wireless Noise-Cancelling Headphones. If you know TREBLAB's series of wireless earbuds, you've got the same 4.2 Bluetooth technology here.
