What is the design of the Shure AONIC 40 headphone?

Shure AONIC 40

Starting with the design, the Shure AONIC 40 are extremely light pair studio headphone with glass filled nylon material. The quality of this material is alright and it does feel robust. The headband in particular is not very flexible, and feels like it can break easily if it stretches a bit too much. However, the metal reinforcement at the joint increase the weight of the headphones and possibly make it uncomfortable to wear during long sessions.

The Shure has done a good job with the cushion and clamping pressure, though. Moreover, there is a good amount of cushioning on the headband that adds to the comfort of wearing the headphones. The ear cups are covered in soft velour, which meant my ears did not get warm during extended listening sessions. The clamping pressure was ideal, and my head did not feel squeezed at all.

The design of the AONIC 40 headphone is very much similar to the Sennheiser HD 400 Pro. In addition, large oval ear cups that snugly cover your ears, and the colour scheme is all black, including the Shure logo on each ear cup, which give it a nice premium feel. The ear cups themselves have decent depth, but the inside surface touches the tip of my ear ever so slightly. It wasn’t much of a problem, though.

Furthermore, the AONIC 40 headphone missing the IP ratings for dust and water resistance. Which means you can’t use this headphone with raining outside or during swimming. The headphone fold flat and collapses for comfortable travel and storage in carrying case.

How does the Shure AONIC 40 headphone sound?

Shure AONIC 40

The Shure AONIC 40 is designed to be used in a studio setting, and it excels the most with high-quality music files. It has 31ohm impedance, which is quite a bit lower than headphones that are designed for casual listening. I would recommend getting a dedicated AMP or an audio interface to power these headphones, but it is certainly usable with most desktops and laptops. During my testing, I used the headphones a lot with an iPad Pro, mostly to test Dolby Atmos music streaming via Apple Music.

As they are studio reference headphones, the AONIC 40 headphones are tuned to have a very neutral sound signature, which means it should have equal preference in the production of bass, mids and trebles. Moreover, the bass is tight and precise with no distortion, and it definitely does not overpower the mids and higher frequencies. Vocals are clear, forward-sounding and clean, and the treble performance is good.

Does the Shure AONIC 40 have good isolation?

Active Noise Cancellation allows you to quiet the ambient noise around you. This is especially useful when you want to listen to music or are on a phone call in a noisy environment.

To use Active Noise Cancellation:

What connectivity does the Shure AONIC 40 support?

Shure AONIC 40

 Shure AONIC 40 uses Bluetooth 5.0 to connect to the device of your choice and supports SBC, AAC, aptX and aptX HD codecs. This means that you have the option of high-quality audio streaming, whether you are an Apple or Android user, which is really nice to look at.

AONIC 40 also supports Bluetooth multipoint, although it does not announce it for some reason. Multipoint works well here, reliably hop back and forth between streaming audio from my Google Pixel 4a.  Simultaneous streaming is not an option, but never with Multipoint.

How long does the battery last on the Shure AONIC 40?

Shure AONIC 40

Shure claims that the AONIC 40 can last up to 25 hours on a single charge, but in our testing we have found that it is more than that. With the ANC turned on, the Shura AONIC 40 lasted 36 hours, 31 minutes at a constant 75dB (SPL) output not the best on the market, but not far off. If you turn off ANC, performance will undoubtedly improve but leaving something like Multipoint Active will get things out faster.

Battery life is superb, and the included Quick Charging feature will bring in 5 hours of use after just 15 minutes of charging. There is wireless charging for talking, but you can always use it when it is charged. The Shure AONIC 40 supports 3.5mm and wired audio connection over USB via USB-C charging port.
