Your listening setups for LTU6?

[Shannon]

So you guys just use your phone speakers?
I thought for it to be really effective you must use headphones or earbuds. Am I thinking too complex?

Also if for whatever reason you do not get in the required loops for the day what do you do? Do you just take more days on?

You have a spectrum between maximum convenience and maximum effectiveness.  You choose what point on that spectrum you are happy with.  For me, there's really no other choice because of the circumstances of my life right now - and for a while now.  And it works.

But if I wanted maximum effectiveness, I would listen to FLAC only, on high end headphones (except of course for ultrasonic, which I would use on stereo speakers).

For not getting enough loops for the day:
1. Make sure that won't happen again.
2. Immediately do as many loops as you missed (if it's the same day). If not the same day, you can return to the regular loops per day the next day or try to add on the missed loops.  I don't recommend you add on the next day unless you missed 1 loop.
