Irritated by annoying computer audio noise?

Banish ALL USB gremlins with the micro iUSB3.0 – our Total USB Solution+®.

Noise. Noise. Noise.

Computers and laptops are inherently noisy. They can emit up to tens of millivolts of noise.

Plus the presence of a ground connection between the computer and the USB audio device can create earth/ground loops. These will impair sound quality and may also cause buzz and hum.

Ifi Audio micro iUSB 3.0

Multi-talented

The micro iUSB3.0 stops all of the above and more besides.

It eliminates USB jitter, ground noise, EMI and RFI, restores signal integrity and corrects signal balance, suppresses frame and packet noise and corrects impedance mis-match.

The only thing it doesn’t do is make coffee!

Make sweet music

Simply plug into your USB port. It will work with DACs up to and above $5000.

Vocals become clearer, more defined, instruments feel more rounded and life-like.

Multi-tasking

And with dual ports, the micro iUSB3.0 operates as a computer audiophile-grade powered hub to serve two devices – just add DAC and HDD.

One source does not contaminate the other.

Back by popular demand

Most products have a finite shelf life but not the micro iUSB3.0.

We were going to withdraw it BUT you guys disagreed! And with comments like this, how could we not keep it around!

…the sounds difference with and without the micro iUSB is striking and goes far beyond what I would have expected. If you do not believe it, try it yourself..If I had to describe the effect with only one word, then that would probably be ‘purity’.”

EMI (Electromagnetic Interference)

EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.

RFI (Radio-frequency interference)

Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.

Top tip: just don’t add water.

Frame & packet noise

Frame and packet noise refers to the jitter that comes from signals being processed.

Impedance mis-match

Firstly, what is impedance? Impedance represents the opposition that an electronic component offers to an alternating and/or direct electric current.

Impedance mis-match is when the maximum power transfer from an amplifier, for example, does not match the impedance of the source.

DAC (Digital-to-Analogue Converter)

DACs convert digital information, stored or streamed by computers, into music we can hear through speakers or headphones.

Every device that’s a source of digital sound has a built-in DAC (TVs, games consoles, CD players, phones, portable music players etc). Dedicated external DACs sound much better than standard DACs used in digital devices such as phones.

Active Noise Cancellation

Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.

Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.

USB3.0’s ultra-speed bandwidth of 5.0Gbps offers an incredibly wide bandwidth, 10x that of USB2.0’s 480Mbps.

Are your devices power hungry? No problem.

This unit is also Bus, Charge 1.2 compliant meaning it can fast charge phones, tablets and even the nano and micro iDSDs!

Kills USB power noise by ‘breaking’ the earth/ground loops in the correct way.

It significantly reduces the system noise floor and makes for better dynamic contrast, warmth and resolution.

Quiet! Active Noise Cancellation+® (ANC+) at work!

Exceptionally quiet power. The measured noise floor is 100x quieter than the common noise filter.

REclock2, REgenerate2, REbalance2® – cleaner, clearer music. The 2nd generation of this technology creates an all new signal, eliminates computer jitter and removes noise contamination to restore a ‘balanced’ signal.

Good to see that a device that is twice as expensive also performs twice as good

As a follow up on the iFi Nano iUSB3.0 here the review of its bigger brother, the Micro iUSB3.0. It’s twice the price, twice the size but does it also offer twice the quality?

Compact products but very high technology, exceptional

These micro are as discreet as their influence on restitution is immediately obvious. To try, Absolutely, but beware, these products are highly addictive!

Why iUSB3.0?

It is a clean power source for USB devices and the air conditioner of the signal itself. It restores the integrity of digital information and suppresses noise transmitted on the ground bus

Something this doctor strongly orders

iUSB3.0 is one of many devices which address multiple USB related issues. Its main order of business is to combat noise, provide clean power to this type of signal and to regenerate it in proper fashion.

The Micro iUSB 3.0 as reviewed by Ates Berberoglu on Headphone.Guru

This is the most impressive part of the reviewed system. According to iFi, it has active noise cancellation, reclock, rebalance and regenerate technologies. The iUBS 3.0 fixes the system’s weakest part with its power regulation inside. It utilises an external power supply to eliminate bad electrical signals and reduce noise coming from the computer. This way, the system becomes quieter and more effortless.

A magic box called Micro iUSB 3.0!” says MacTechNews.

iFi Audio Micro iUSB 3.0 is a USB hub and filter, the aim to which is to free the computer audio stream and the USB power supply as well as possible from all possible electromagnetic ‘dirt’…The iUSB 3.0 provides dual USB ports, only capable of transmitting power and data….The sound gain with the Micro iUSB and Gemini cable was enormous in my tests….the sounds difference with and without the iUSB is striking and goes far beyond what I would have expected. If you do not believe it, try it yourself..If I had to describe the effect with only one word, then that would probably be ‘purity’.
