Review on 🎸 LEKATO 2.4GHz Wireless Guitar System with 6 Channels, Stereo/Mono 1/4” & 1/8” 2 in 1 Plugs, Built-in Rechargeable Lithium Battery - Ideal for Audio Electric Guitar Bass by Omar Card

integrated 3.5mm jack (instead of 1/4) means I can use a 3.5mm to 1/4 adapter IF it has a long enough collar or barrel and fits into the S - the ones supplied are not long enough for the S series. If the stem or collar on the adapter are the more common short versions, like the ones that come with the kit, they still won't fit. easy to use, good sound quality. The battery is good enough to last a few workouts, but it could be better. This is probably a limitation with many of these small wireless connections, it's difficult to fit a very large battery there.
