Work great so far
Great so far,only used for our pastor twice,it was easy to set up, delivery was on par, price was great,not a complaint but I would prefer it to have a mute switch,but not a big deal,I can't speak of longevity yet, however it was easy to adjust volume so static did come from the speaker's,I used the lil bit of reading materials trouble shooting guide to whoop that problem,the sound is really good,we used the head mike because it picks up easier than the lapel mike, hope this helps

Shockingly good
There's no disputing these are very basic and very cheaply made. But cut to the chase... ...we all want a mic to work with sufficient gain to be low-noise, that is to say 'usable'. These do. I bought them in a pinch, not having the requisite dollars to replace the failed "Better Brand", but honestly, these will stay in the rack for as long as they live. I'll never produce an $800/seat rock show, but for weddings and the like in various places, these really are more than sufficient. Battery life is as good as the 'Better" when running 3500mWh rechargeables.

Great for in-home karaoke parties
We use this for karaoke in our house, connecting this and our laptop (for music and lyrics) to a big Ion speaker and it works great. Sound quality is good for what we use it for. I love that we can manually adjust individual microphones as well (you know, there’s always one or two people in a group who sing waaay too loudly and need to be turned down a notch!)

Great product!
Great sound! Used for the gym so students can hear me teaching. Only gave it a four star because the cords that connects the headset to the Box are too short otherwise it would have been a five star.

Great for our church setting
Working well in our church setting, ordered both frequency sets so we have 8 mics with no interference

Worth the money!
For the price the quality is excellent, and the sound quality is good. Range is surprisingly good, too. Is this professional level - no, but for church group or small community group play operating on a budget this is fine. It is perfect for a garage karaoke set up for family fun.

Mic Packs drop connection to receiver - seller Yin ProAudio will not process a replacement order
First time I tried to use this product, the mic packs would not stay connected to the receiver. Brand new batteries, mic pack and antenna exposed (not covered by clothing or in a pocket). Speaker no more than 20 feet from the receiver. The connection indicator lights on the receiver kept flickering off and on and the mic would cut out in tandem showing that the connection was indeed dropping constantly for no good reason. Even worse - the seller: Yin ProAudio I figured maybe it's a faulty receiver or just a bad couple of mic packs. Instead of requesting a refund, I asked for a replacement first. At first everything seemed great. Amazon gave me my return label, and an order for a replacement was placed immediately. BUT the seller put my order on hold for "inventory issues." Even though they have never shown as Out of Stock on the product page for selling more of them. I thought, well, maybe they need to see that the return item was shipped. But it's been almost a month since I shipped the return item. No communication from the seller, and my order is still on hold. I am trying to figure out how to cancel my replacement order and get a refund. But that isn't really clear since the replacement order is for $0.00. But all in all, there was no good here. I got a faulty product, and the seller is terrible.

Abbiamo usato i 4 microfoni ad archetto contemporaneamente. Uno era collegato con uno cavetto a doppio jek allo smartphone per fare partire delle tracce musicali. Direi suono della voce pulito e senza interferenze. Consigliato da me. Usato per uno spettacolo per ragazzi all'aperto e inseriti in una cassa autoamplificata. Ottimo rapporto qualità prezzo.
