Excelente interfaz para usar como monitoreo buen material y alta fidelidad en el sonido Gracias Amazon

This works perfect for our IEM rig my band used all four body packs from pur woreless system and as a drummer I use a separate mix than the rest of my band I highly recommend this item battery life is excellent played 3 shows before needing to charge

They work well. They even have a volume button on them. They have lights on them that will tell you the battery strength as well. They will conflict with the wireless guitar gadget though. The signal from both will cut in and out no matter how many times you change the frequency. You can use one or the other. These for headphones or the wireless guitar plugs.

This headphone wireless adapter does not work fully plugged into a device, I tried it with 3 different devices and you can't plug it in all the way or it won't work you have to have it half plugged in to work. I tried just a 1/4" adapter with normal headphones to make sure it wasn't 3 different pieces of equipment that were bad, just using the adapter plug all of the equipments Jack's worked fine!

Great reception and battery duration

I like Joyo products, and I had high hopes for this unit, but unfortunately the JW-07 just doesn't have an audio quality that I can live with. Perhaps it was just my unit, but here's my experience after three weeks of use both at home and in live performances:Bad:- The noise floor, right out of the box with nothing connected, is high. The hiss in my ears from the unit is noticeable when playing my guitar, and even just listening to playback.- The distortion level is significant at lower frequencies. I'm a bass player, and from about 100Hz down it distorts, similar to the sound of a dying preamp battery. This was consistent across different instruments, even going direct with no effects in between.Good:- really low latency, as in not noticeable.- great battery life. I routinely ran over three hours continuously, and the battery indicator never dropped below 75%.- no interference issues, even at a venue with a radio station nearby.As others have mentioned, it's mono, but for less than $40.00 I don't think it's reasonable to expect stereo operation. If it weren't for the noise/distortion problem, I would definitely use this on stage; I can forgive being able to pan given the cost. Unfortunately, that distortion gets worse as other instruments enter the mix. I wouldn't purchase this unit again, but I'll definitely try the next version.

Need to make sure where it is attached. May lose communication

I’m a drummer and I use these for my IEMs at church. This works PERFECTLY - connects immediately with great sound and no interference, delay, or distortion. They work just as well as the typical $250 ones… well worth the $35 price!
