It all started with you man. I wouldn't have even tried using a rechargeable BT dongle.
Ever since then I have wanted a better option. My courage to try this on a popular box finally got to me and off I went.
I'm glad the technology has advanced to a level that I like.
Now, I ordered a 3rd style of BT module today. I will be getting a small stock of switches (because I have 4 M70's I still want to BT).
I can't wait to test, review, and compare the 3. I already see huge differences in the first 2.
The first 2 BT M70's were bought to install, test, and sell.
After I decide what BT module I like best, then I will start to BT a lot of my blasters INCLUDING the OG TDK 2 speaker, JVC M90, JVC M71, and a handful of others.
