Enjoy the silence! Our Active Noise Cancellation II® (ANC II) tech means that measured noise drops by 100x or 40dB in comparison to the common noise filter.

iSilencer+
Does your USB audio system suffer from annoying background noise?
Our new and improved iSilencer+ is a must if you want to enjoy vivid, open music.
Enjoy the ‘new’ silence.
Connecting audio gear via USB can have pros and cons. While capable of passing hi-res data at max resolution and allowing bit-perfect transfer, USB was not created specifically for audio.
It carries both power and data. It is susceptible to electrical noise, for example, from the computer’s power supply. This has a negative effect on sound quality.
Fear not! At iFi, we first banished these gremlins with the iSilencer3.0 and now, we’re making silence sound even better with the iSilencer+.
Take a look at our Noisebusting Tech Note.
Plug. Play. Pop free.
Electrical noise on USB causes errors, data loss and poor signal integrity. You will hear these as distortion – pops, clicks and delays.
The iSilencer+ solves all of this quickly and easily. It plugs directly into the USB port of your computer as a link between your computer and your DAC.
It will remove electrical noise, both EMI and RFI, at source. Your music will seem clearer, warmer, and more transparent with improved bass.
Double whammy.
As well as plugging the iSilencer+ into the active USB port between the computer and DAC, it can also be plugged into unused USB ports too. This will further reduce radiated EMI.
Each time the number of units (and therefore the number ANC II circuits) is doubled, noise reduction capability also doubles.
Double whammy.
Silence. Improved.
The iSilencer+ uses our latest Active Noise Cancellation II® technology. It decreases noise in a similar way to noise-cancelling headphones.
We use our REBalance® tech to get rid of clicks and distortion.
We’ve upgraded the circuitry; low-ESR tantalum capacitors have been added for improved input and output filtering. Filtering capacitance has been increased 10-fold.
Why iSilencer+?
We’ve added several flavours – it comes in 3 versions and includes the newer USB-C connector.
- USB-A to USB-A
- USB-C to USB-A
- USB-C to USB-C
Why did we name it iSilencer+? Simply because it just gives you more – more options, improved filtering, and just more silence.
REBalance® literally rebalances the signal to address the common problem of clicks caused by jitter. This is a form of digital distortion that leads to data ‘packet’ errors and cold harsh sound.
Our technology re-balances the signal to ensure that the digital signal received by the DAC is identical to the original source, no matter which audio format is being played.
‘SuperSpeed’ USB 3.0 has a more exhaustive wiring specification which allows for a greater amount of audio transfer while still being backwards compatible. The units incorporate high-quality gold-plated connectors for optimal signal transfer.
Based on military tech, our improved Active Noise Cancellation II® actively cancels all incoming noise.
It does this in a similar way to active noise-cancelling headphones – it generates a signal identical to that of the incoming electrical noise but in the opposite phase, actively cancelling it out. This is highly effective at removing low- and mid-frequency noise, while passive insulating filters deal with higher frequency interference. This combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.

Solved the high pitch whine
When recording audio with either a USB microphone (a Shure MV7 or a Blue Yeti in my case) or through a 3.5mm jack, my PC adds a high pitch whine. Also noteworthy, the whine isn’t there on my MacBook using any of the above, just with my PC desktop. This dongle removed that whine when recording through it with the USB microphone.
The dongle has some wiggle when plugged in, otherwise it’s perfect. Well worth the money in my case, since the computer and the microphone are both expensive and this was the last thing standing in the way of a clean recording.

iSilencer+ USB audio noise eliminator
“The power of the opening trumpets that lead nicely into the vocals is fantastic. The music emerges from a blacker background with the iSilencer+ fitted. Vocals suddenly have a greater energy and dynamic presence and the trumpets have a clearer and more refined sound. The iSilencer+ lives up to its claims and consequently is an excellent value for money accessory.”

Great noise filter
Definitely removed a lot of noise. A bit pricey but worth it if you use good headphones.

Two mid-tier DACs saw an obvious improvement in SQ.
I have used this in two setups and it brought broadband/net improvements in both setups.
The first was a Roon Nucleus Plus (really an a Intel NUC 7i7BNB) -> isilencer-> Wireworld Starlight 8 USB A->B -> RME ADI-2 FS v2 DAC. Without the iFi, the sound has a grit and edge to it that want great for long listening sessions. With the iFi, these aspects disappeared and in their place was more refinement, better air, blacker backgrounds, and zero listening fatigue. Also, fatter and deeper bass. Spotify became genuinely enjoyable as opposed to passably convenient.
The second setup also begins with my Roon Nucleus to the iFi, then an Audioquest Cinnamon USB A->C into a Matrix Audio Mini i Pro 3. Same list of improvements, but an even bigger difference. This one really benefited from the noise reduction.
USB Audio obviously isn’t perfect and this device serves its function as advertised. Hard to imagine a more effective $50 to spend in a system.

THIRD TIME’S A CHARM
WOW! I have tried the other editions of the iSilencer and I have to say, nothing. No change at all. I figured I would give IFI another chance since I really do love their DAC/AMPs. I just plugged this baby in to my ’19 MBP and connected my newest DAC/AMP acquisition from Earmen. The TR-AMP. I plugged in my very revealing Master & Dynamic MH40s’ and I was blown away from the first note! I wanted to post this right away for all that are still sitting on the fence wondering if they should spend $50 here..

not snake oil at all.
if your setup is trash its always gonna be trash. this thing isn’t going to work miracles. but on a clean linear setup this thing really drops the noise floor noticeably, gets rid of a lot of grain in literally everything from music to peoples horrible mics in discord.
i have a pretty high end setup and this little usb filter for $50 made a huge and noticeable difference that a lot of people end up paying thousands of dollars for in the form of a way overpriced DAC. would highly recommend to anyone with an already decent setup as it will truly bump it up to the next level of clarity for almost no money in the scope of audio equipment.

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.
Bit-Perfect
If a file is “Bit Perfect’ it means it has stayed the same. For example, if a PCM file is played through a DAC to improve the sound quality and the DAC does not change the file format. The file is ‘Bit Perfect’.
Common Noise Filter
The common noise filter cuts out most noise gremlins found in typical audio systems such as RFI/EMI.
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.
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’.
