Nice review. Do you know the latency spec on this unit?

I would think 5ms is too much, especially if there is leakage from the outside around the in-ears. 5ms is a 200Hz comb filter. Aaron, any experience of artifacts related to the latency?

I didn’t notice anything. Also it sounds great with ToneDexter as you get that awesome processed tone right in your ears!

What is the latency of traditional IEM systems? Isn’t it the same as standing 5 feet from a floor monitor?

Funny enough, I'm just exploring this issue at the minute. I've recently bought the Wi Audiolink Pro for various wireless odd jobs and decided to try it as an IEM system as I'd heard it discussed. It was suggested that:
* 5ms is akin to being 5ft away from a speaker * Only audiophiles will hear a combing effect * Only purists will be bothered by it. Whatever "science" (I'm a fan of science) is proposed to support these suggestions I can say with confidence (for me) they are not borne out by experience. I've tried it in conjunction with a traditional wedge and the disconnect is as offputting as it is with bone-conducted vocal sound. Non-vocal work is more forgiving but if you're playing fast moving tunes it will show. Latency in the Wi system is reported to be around the 5ms mark and it's on the verge of unusable. I may just take it along on my next trip as my only other option is my rack mount unit which I want to avoid carrying but if I can't get used to it then I'll stick with the current setup. 5ms is a long time in live audio.

I have an Audio2000 wireless and I do not notice any latency issues. Now if Aaron says he does not notice any latency issues with the xVive, I am sure that would work for me.
I tried a low latency BT transmitter into a low latency BT receiver and even though there was a slight latency effect, it became unnoticeable with use. That was an inexpensive solution and just plugged my BOSE earbuds in. I like the format of simply plugging the transmitter into the board or amp. No extra lines, cables to mess with. I think it is a pretty cool solution and especially when you are doing solo work and want to travel light. I think it is a great idea and the folks at xVive are finding great options for us all. No, I have no interest in xVive! Thanks Aaron! davidc |

Among my other fun roles I am sound tech to an Irish trad/rock/country band.
We finally persuaded the drummer to try out an IEM system. As he is sat at the kit all the the there seemed little need for a wireless setup so he invested in a headphone amp. He has a little drum multicore (m/c) with a spare "out" beside him so we hooked him up to that, Aux send from desk to m/c, XLR from m/c to h/p amp (mono) to ears. He has struggled with this so I borrowed it for one of my own gigs recently to iron out issues. I have concluded his problem is with IEMs in general which we will work on. The h/p amp sounds better, is more portable, doesn't drop out and there is effectively zero latency, is cheap and batteries last many, many gigs. My only caveat to this is that my desk has EQ and limiting at the Aux out which is important as I wouldn't want to send the wrong raw signal to the h/p amp. This said I often see wireless IEMs set wrong so that limiting and EQ might as well not be there. Unless you're moving round a lot - strongly recommend, and that is from a Behringer non-fan: https://www.andertons.co.uk/behringe...SABEgKl7PD_BwE

I've spent a lot of time looking at various IEM solutions. Ultimately I went with a Shure PSM 300 as I've become a massive fan of stereo IEM mixes. If you haven't tried stereo, you're really missing out. Game changer for those with multiple tracks/channels.
I use XVive's wireless mic system and like it. They make good products and this looks like another winner for those seeking a simple setup. Just wanted to chime in for those looking for a stereo IEM mix- you'll need to keep looking.

I'm dusting off this thread for a bit of an update.
I explained earlier that I had been using a Wi Digital radio 2.4gHz box as a headphone monitor for sound-teching with good results but when I tried it as a player I found the latency to be just on the wrong side of useable, particularly when I also used a guitar system with similar latency numbers. Well, one of the guys in the band asked me to explore IEMs for him and I picked up the Xvive U4 for him and used it at my own gig last night. The U4 behaved impeccably, even when paired with that guitar system. This would suggest either: 1) the numbers on the Wi Digital unit don't represent reality and should have been reported at something more like >25ms 2) I'm an idiot 3) both Just thought a retraction of sorts was justified. On a related topic, what sauce would the forum suggest with humble pie?
