Review (5/5): Great sound quality. Go to the YT video comments for the pairing directions
1. Pairing. The manual is hard to follow. Read the comments in the product's YouTube video for easier pairing instructions.
2. Sound quality is really good, on par with devices that cost 2x to 5x. The only downside so far is that a few environment sounds (e.g., barking dogs) are loud and sound closer to you than they are.
3. Earphones. As everyone's noted, the ones in the set are not great. The same brand sells better ones, get those, they're worth the investment.
4. The radios lose their pairing if one or more of the radios off or on in the wrong order. Plan to re-pair before your first game of the day.
