The THAT 1646 OutSmarts Breakout Board offers an easy solution to adding a balanced audio output to your circuits. The THAT OutSmarts technology has been designed as a high-grade analog line driver and offers a low distortion and high common mode rejection in real-world audio applications. Each breakout board combines the THAT 1646 IC, its supporting components and a ¼" TRS (Tip Ring Sleeve) socket. With these powers combined, you will find it very easy to use the output drivers on breadboards and in projects!

The THAT 1646 OutSmarts Breakout and its sibling, the THAT 1206 InGenius Breakout, perform mirror-image signal conversion. While the InGenius is a balanced-to-unbalanced input receiver, this OutSmarts is an unbalanced-to-balanced output driver. We have made sure to break out each pin you need to utilize the OutSmarts board including the unbalanced input (IN), the positive and negative power supply rails (V+, V-) and, of course, ground (GND). Additionally, adjacent to each leg of the socket are test points for the signal (T, R, S) and normal (TN, RN, SN) contacts.

Weirdly thick material, I wasn’t a fan but it’s a good sleep shirt

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).

Fuzzballs get wearing once
Color: Black, Size: X-Large
Very smart to wear, but the quality is terrible so after one wash the collar start fraying and fuzzballs start forming. Very disappointing.
