Most will use the more expensive version as a shout speaker between the stage and FOH position, but for my budget, these are fine. They may sound a bit more distorted at high level, but you can still understand what you are saying.
The sound is not great for music and the Bluetooth function could have been skipped, but for talkback, it works well.
Just keep in mind that it does feedback a lot faster then the more expensive version.
In conclusion: get the more expensive version, but if you are strapped for cash, these are good.
