SONY Bluetooth Stereo Headset

Check out the product page and check out this “excellent” review over at PCmag.com

For the SONY MDRZX770BT/B (not the noise cancelling), the Features tab says it has bluetooth 4.0 but the Specs tab says 3.0. Which is correct?

Also, why is the warranty only 90 days woot? Are they refurbished? They are listed as new.

Everything we found shows BT 3.0 so we’ve updated the sale.

They are new. Sometimes vendors ask us to carry warranties.
