El único defecto es que a veces se oye interferencia, pero es muy poco y para el precio no es tan incómodo, pero es mucho más cómodo que tener cables, aunque debe haber mircrofonos mejores, dudo que a este precio. ## Features - UHF Frequencies--The wireless lapel microphone system has 20 frequencies selection for seamless, interference prevention operation.An easy-to-read LCD information display provides constant monitoring of system operation, including receiver low-power indicators.

Because this receiver output is about the same level as a wired mic. It must be plugged into a 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line inputs which require a higher level signal than a mic provides, the mic will be not suitable to be used with it, even you add an adapter. The sound will be soft and hard to be heard. **Q: Can I plug the receiver into my iPhone, audio mixer, or Mac to record the audio?** A: Sorry, it works with only audio mixer that has 1/4" mic jack. If you need a mic to use with Mac, we have the K031 (Asin: B074C125TN) USB wireless lav mic. But neither of them will work with iPhone. **Q: can it be used for singing** A: It will be more suitable for speaking than singing. We would recommend the handheld mic K025(ASIN:B0795PNCBG) or K035(ASIN:B01MT6AAIC) for singing. All these mics need to work with speakers/amps that has 1/4'' mic input. ## Customer Reviews ### ⭐ Disappointed *by A***I on 1 December 2022* It is not my first product off Fifine I'm shocked that the mic didn't work I tried everything on the manual to make it work according to the problems encountered it connects for half a minute then it stops working and now I ended up with a non working mic ### ⭐⭐⭐⭐⭐ Es perfecto y barato. *by R***A on 9 December 2018* Tengo varios meses usandolos para grabae mis vídeos y me ha sido de mucha utilidad porque evito estar usando clables que se enrredan, además de que tiene un let que te avisa si la pila funciona bien o ya hay que cambiarla y ambos micrófonos funcionan perfecto para la ocasión, yo uso la diadema para vídeos solo y la otra para vídeos con colaboradores porque para vídeos solo tendría que estarlo agarrando y es incómodo.
