A:Answer The HS70 wireless has a usb dongle to connect to your ps4/ps5 or pc. This does not work on Xbox. The HS70 Bluetooth can connect to your phone, ipad, or computer/laptop via bluetooth. You can also connect your HS70 Bluetooth via 3.5mm on xbox/series x, ipad, ps4/5, phone, and laptop/pc. The HS70 wireless has both 7.1 surround sound and stereo, while the HS70 Bluetooth only has stereo. But if you ask me I'd say 7.1 surround is bad anyways. Unless 7.1, or wireless connections using usb dongle is a must for you, I'd say the HS70 Bluetooth are better considering they're the same price.
