Yamaha PSG-01S

Ease to use with good mic function! Packs with not bad sound quality for music but great sound for voice.

No Wifi. Doesn't come with battery need to be plug to USB.

Excellent device and the quality of it and the sound it just awesome.

Clearly value for money

Small and portable, ideal for traveling with a laptop. Works very well. No need to raise my voice when speaking on the unit, worked all the way out to 6 feet.

almost none.

Small, easy to use, big sound

Not great with 10+ people
