So I got this M3 to work with my M4 speaker in a multi room setup at home, I would have gotten another M4 but with the M3 having been advertised as more powerful and better sounding than the M4 (Not to mention that I had no need for a 2nd portable speaker

Well, if you can afford more than one M3 (or an M4

For what it's worth, I tested the M3 with a power consumption meter

The M3 also gets quite loud

So, I bought the GGMM M4 Portable and GGMM M3 Wireless

Apparently, the M3 doesn't like the 5 MHz band or sharing the 2.4 MHz band too much,

I found the M3 to be a little clearer than the M4

For the quality of audio the M3 is definitely worth the money

To her, the M3 sounds great!

Of course, all the features in the world won't make a poor-sounding speaker any better, and this M3 performs great in this respect as well.
