Stereo TRS to Duel XLR3m

This worked really great with my system application. I use it to hook my laptop to my sound board, where I can use two channels to use different effects at the same time while playing my music. The cable length is just right 6.6 feet is about what you need to keep from limiting movement on stage.

used this to run my Rokits into my MacMini when they were not being used coupled to my Presonus mixing setup. Works well,

Had a spare Coax running from the Summer Kitchen to the stereo located inside and was having a hell of a time getting this IR Repeater to work.  Tested the ccoax able and remotes independently then read that a 3.5MM male to male stereo cable could replace the IR Transmitters and since the Sony stereo I have has an "IR IN" port I dug through my cables and had one.... once  the stereo cable was in place the remotes worked flawlessly.... So my problem was the alignment between the transmitters and my Sony Stereo.  I give it four stars because there should be better documentation on the clips that come with the transmitter, the receiver side was well documented; also it would be great if they included the stereo cable for those with IR IN ports on their equipment.

Update:
windows has it's own drivers for that thing, so you just ignore that garbage software from avantree
set in pairing mode your headset, connect it from start>settings>device>bluetooth and then go to bottom right corner>click right to  sound>playback devices>select headphones STEREO and click make default

Sometimes works in stereo, sometimes not (audio call quality) even with the soft installed
The soft is like in 2000, you cant figure it out without instruction
very dissapointed

Purchased this unit to use my turntable with new Yamaha RX-V867 AVR since it does not have a dedicated phono input. Plug TT into preamp and plug pream into analog audio input on receiver - works perfectly. Added functionality is to convert my vinyl to digital format! I have not yet used it to convert to digital so no input there. Product fills the main purpose for which it was purchased.

I used these to convert my pair of&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Audio-Technica-ATH-M40x-Professional-Studio-Monitor-Headphones/dp/B00HVLUR54/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Audio-Technica ATH-M40x Professional Studio Monitor Headphones</a>&nbsp;to take a standard 3.5mm cable, and ultimately to be able to attach a bluetooth transmitter to make them wireless. I ordered the three pack and was really glad that I did. Only 1 of the 3 pieces I received fit inside the whole where I removed the proprietary Audio-Technica fitting. If you're using these for a similar refurb, be aware.

Other than that, sounds great.

Before the actual review I need to clear a few things up with this item.

Contrary to what everyone else seems to be saying about these, they ARE STEREO.  It can function as a mono iem, but you will lose a little bit of signal in the left ear (which I'm sure many people noticed) because it's being fed the negative signal through the XLR cable.  I understand where a lot of the confusion is from; first, Elite Core didn't do  great job of describing this on here. Second, in almost every real world situation XLR cables (a.k.a. mic cables) are mono, but not always.

 Quick rundown on XLRs.  XLRs have 3 pins, a positive signal, a negative signal, and a ground.  On a microphone the mono signal is split in two and sent down two pins on the XLR instead of just one. They are also called balanced cable for this reason.  This makes the signal stronger on the other side and Much less likely to get interference.  That is the reason they are used.  But because these cables have two completely separated wires running through them, with the right equipment (or adapters in my case) you can send a Left signal down one wire, and a Right going down the other.

This unit was built to do this.  It is meant to be used with a stereo 1/4inch to XLR cable (which is what the Pro Hex 10 & 18 cables are) with Elite Core's own personal monitoring system; which has a stereo 1/4inch jack as it's output.  This unit is wired internal not to recombine the two signals inside but keep them separate as they reach you in ears making it have a left and a right side.  If you look at the pictures I uploaded it might make a little more sense. Anyway, to the review.

REVIEW:
This little guy is fantastic. It sounds great.  I can notice no major coloration of the sound using my standard in ears. If you don't have a headphone jack as your input for this or don't have two outputs on whatever you're using to run this in stereo, you're going to get a little loss of signal in your left side.  If your mixer supports it you can flip the phase of the output and then it will be the right side that has a little less signal.  While I wish they did add a feature that would enable this to be used perfectly as a mono and stereo iem, it makes sense since this was not meant to be used as a standalone device but with Elite Core's own monitoring system.  This is a great unit and I would recommend it to anyone.  If you're looking for a fully functioning Mono iem, look at Behringers P1 as it supports both stereo or mono signals. Behringer's PM1 is meant to be stereo same as this one.

I use this along with an Art USB Dual Pre preamp to get an XLR mic into my Canon 60D camera, and this works awesome.  This lets me take the left and right channel outputs from the preamp and turn them into a single stereo input into the camera.  No sound quality loss whatsoever.

Nice and handy to convert your XLR jacks. It's like having two in one. Works fine for me every time.  In our church settings like conventions.

I bought this adapter for my RodeLink Filmmaker wireless lavalier mic system.  I use this mic on my Canon XA20 camera.  This adapter is needed for the XLR mic input on the camera.  This adapter could be used for other 3.5mm items converting to XLR.

Works great and easy to use. Converts vinyl records and cassettes to mp3s. Able to listen to records and tapes while recording. Really can boost up the input sound while recording. It is a great replacement for my old stereo receiver which no longer works!

Connected and instantly worked with the following setup:

Roland TD11k electric drum set > MIDI OUT (using MIDI IN connector from EMU cable) > Apple Lightning to USB 3 camera adapter > iPad Pro > Garage Band app > Drums mode. No additional setup required, instantly detected the pad hits

I bought this adapter in order to use my iPod to record the headphones output from my band's sound board at live gigs. It takes a 1/4" TRS or TS plug and turns it into the iPod's TRRS mic jack. I then use the built-in Voice Notes app to record the output and work with it later. The adapter is simple and seems fairly durable; it has strain reliefs built into the cable. One thing: I believe that the iPod's jack only allows monophonic recording, meaning that if you send a stereo signal into the adapter, it will be summed and recorded as a mono signal. That's not a problem for my usage pattern, but you might want to know about it if that matters to you.

After using it for a while, I also bought the app for Peterson's iStroboSoft, a digital strobe tuner. I like using it, but it's very touchy, and depending on the instrument I'm using, it doesn't always pick things up well. I suspect that's more about the instruments and less about the adapter, though. I don't know whether iPod mic jacks are high- or low-impedance, and I don't know whether this adapter does any impedance matching, although I suspect it doesn't.

Bottom line, it works. I can get good-quality archive recordings of what the band sounded like, and I can use my iPod as a high-quality digital tuner. That's worth the price of admission for me!

I purchased the Sony ECM-CS10 to connect with on of my Tascam Digital Record (DR-40 or DR-70D) via XLR Adapter.

The ECM-CS10 is very noisy microphone and unusable and not recommended for client work, the audio quality if far less than what I expect.

Successfully connected my Cyberacoustics Headset with microphone (got from Amazon.com) to my new Yamaha RXTV-477 stereo receiver using this Y connector and a 3.5mm to 1/4 inch adapter I got from Amazon.com

I purchased 2 of these products and they are both defecrtive.  Per the description, they are supposed to spit a male 3.5mm (TRRS) audio adapter into "two 3.5mm (TRS) male connectors, allowing you to connect a 4-position headset (audio & microphone) to a computer Laptop that has separate microphone and audio ports."

What I received does not do that.  The microphone signal from the TRRS side is abandoned, and the stereo output signals are split into two duplicate two 3.5mm (TRS) male connectors.  Plugging a stereo output lead from headphones into microphone port on a PC is not going to work.

I spent 3 hours trying to figure out what was wrong with my computer's setup before I finally broke out the multimeter.  Once I got to that point, it only took about 30 seconds to figure out that this crap product that is just wired wrong.  Amazon will refund my purchase price, but I cannot get my 3 hours back.

This is a great cable to have in your box.  Everywhere we find the 3.5mm 1/8" stereo jack and interfacing it to XLR is always important.  This is a stereo cable so the tip and ring go to the two different xlrs with a common shield to the cold terminal on the xlr.  I'm using it to get analog audio from my pc's audio out jack into my XLR recorder (marantz pmd-661)<a data-hook="product-link-linked" class="a-link-normal" href="/Marantz-PMD661-Portable-SD-Recorder/dp/B001O9X51W/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Marantz PMD661 Portable SD Recorder</a>&nbsp;which has a line level input on the xlr's.  I can also adapt xlr mics to pc's mic in with xlr adapter cables.

My PC motheboard has 6 3.5mm TRS jacks from the audio chip out the back, plus an optical connection, which is the order I made with this cable.  I also got a 6' lightguide cable and a converter to RCA digital audio for my recorder which now gives me a number of options to link the two.

I've come to trust HOSA cables and these are no let down.
