ESSENTIAL device for all IEMs!

I've been looking for a product like this for a long time. I'm a professional musician and I've been using IEMs (in-ear monitors) for almost 20 years. The problem is that IEMs take very little amplifier power to make them dangerously loud and practically all professional (and even non-professional) headphone outputs are designed to drive headphones that need a lot of amplifier power to attain usable volume. Using IEMs with typical headphone outputs means your volume knob is positioned at just about it's lowest setting. This means that most of the room you have left to turn up the volume will be WAY too loud and can cause instant permanent hearing damage. When the volume knob is that low (and you're still getting more than enough volume) means that you will likely hear noise (hiss, hum, etc). The IFi IEMatch it easily solves these problems. You can turn the volume knob up, the levels are safe, and the noise goes away. I believe this an ESSENTIAL device to use with any IEMs for any use - professional or recreational. Now I can plug into my high-powered headphone outputs in my mixers, dedicated headphone amps, even my iPhone, and have the volume knob set at maximum and still have very safe listening levels (90 dB RMS) using the Ultra Sensitivity setting. If I ever need more volume, the High Sensitivity setting allows this and still keeps the output from allowing dangerous levels get to your ears. The IEMatch allows the monitoring equipment you use to operate in the way it was designed by allowing proper gain staging. FINALLY a device like this has been made available for consumers (perhaps you can make your own in-line resistors but you really have to know what you're doing; I don't). I have tried this with the Sensaphonics 3D Ambient system and JH Audio JH16PRO IEMs with amazing results. Audio quality is unaffected and is totally transparent to my ears. I did not try the balanced output feature or the airplane adapter. The build quality is excellent and feels robust for an adapter. For $ I see it as insurance for the safety of your hearing because as soon as it's damaged, it's damaged forever. Highly recommended for any and all IEMs and ear buds.

Do your earphones suffer from irritating hiss and pop Not getting the full impact of your music
The iEMatch puts an end to unwanted noise and brings your tracks back to life.

The perfect match
Do you find that your headphones/IEMs often have a background hiss from your source Or do you listen really loudly to try and get the full 'quality' of the music If so, then we have your perfect match - the iEMatch.

Highly strung
This original 3.5mm version is perfect for ALL headphones/IEMS using a 3.5mm headphone jack. Simply connect the iEMatch between them and your source for reduced background noise and hiss. Some headphones are more sensitive than others so the iEMatch has both High and Ultra sensitivity settings to boost your sound. Choose which best suits your headphone.

Get back your lost Bits
It also provides a more open and transparent dynamic range and increases the usable volume range. This means you can increase the digital volume and get back the resolution you lose by listening at less than full volume. Rediscover the lost high-pitched note of the E-string or the low rumble of the bass drum.

Up, up and away.
Our small but mighty iEMatch works with smartphones, DAPs, computers and in-flight travel systems. A top tip - take it with you when you fly - no more painful soundtracks to inflight movies. It works wonders. And for good measure we've added memory foam earplugs (they really do work!), an aeroplane adapter and travel pouch. A perfect little travel kit - great music and the chance to enjoy a power nap.

Did you know you normally lose at least 2 Bits of resolution when listening to your favourite tracks This is because you can't listen at full volume. Using the iEMatch enables you to turn up the digital volume and get those 2 Bits back. Choose from ultra or high sensitivity to fine tune your tunes!

Balanced or Single-Ended iEMatch automatically converts to give you the best listening experience using the 3.5 TRRS-Balanced headphone jack. Headphones may be fitted with a TRRS jack and a switch to alternate between unbalanced mode (even with microphone) for direct connection to a smartphone and to balanced mode for use with suitably-equipped DAP/DAC/headphone amplifiers. The 'S-Balanced' TRRS system by iFi provides a way to select the TRRS plug to offer either a balanced connection or a single-ended one.

It uses premium components from 6063-TS aluminum - magnesium alloy through to the signal transfer cable which is a 6N silver copper matrix. Add in the gold plated TRRS-Balanced connectors and there you have it - game, set and iEMatch.
