I haven't read the specs but it doesn't have a 1/8 stereo jack, only bluetooth. The 1/8 plug transmits a wider range of sounds. The human ear can hear 20-20Hz, this speaker claims to be able to reproduce 20-20Hz, but Bluetooth can only transmit 2400MHz - 2483MHz. So Sony claims that 400MHz is below the lower limit.
