The SP01 is definitely not a WM12...... Way different it actually assist with signals by choosing filters that change a frequency and sound ........ It's a cool little box.....
Yeah he can add Wi-Fi or Bluetooth with a speaker and now the SP01 will cost $399.00 and be a bit larger too ...... I got mine from Rob's for $199.00 and is very small and light.
Works like a dream and I don't wear headphones anymore.
I take it with me in my backpack. When I find a Target with the 4500 I take out the ORX just the coil and PDA and find it that way it's quicker........
