Shure Aonic 5 Guide

Wired in-ear headphones are a dying breed, especially at the budget end of the market, but manufacturers with a rich history in this category don’t seem ready to pull the plug just yet, especially when it comes to more premium pairs.Take Shure, for example. It boasts years of experience in the world of in-ear monitors, and a number of five-star ratings for its audiophile headphones would suggest the company knows a thing or two about making a decent pair. So, can we add the Aonic 5 to that list?At £449 ($499, AU$879), these earbuds are the top in-ear model in Shure’s Aonic range. On paper, their design credentials look suitably impressive. The Aonic 5 use three high-definition balanced armature drivers in a dual woofer and single tweeter configuration.You can actually get a closer look at the inner working of the buds through the clear section of each earpiece. It acts as a window and makes a welcome change to the dull black plastic used to cover the majority of headphones that pass through our test rooms. The Aonic 5 are available in three different finishes – Matte Black, Gloss Red and Crystal Clear.Each earpiece uses an MMCX connector to attach to the supplied headphone cable. This makes it easy to switch the cable out in favour of Shure’s optional true wireless secure fit adapter (£175, $179, AU$309), which can transform the Aonic 5 into a pair of wireless earbuds.The headphone cable also includes simple in-line controls for volume and playback and a switch that allows the controls to work with either iOS or Android phones.Anyone who has seen or used Shure earbuds in the past won’t be shocked to discover that you have to loop the headphone cable over each ear. It takes a bit of practice to make it a smooth process but they do feel very secure in place.As you’d expect, Shure provides plenty of tips (quite literally!) to help you try and get the perfect seal. You’ve got three different sizes of Comply Professional P-Series memory foam tips, three sizes of more rounded foam tips, three sizes of silicone eartips and one set of flanged tips. We found the isolation to be excellent on the whole (Shure claims that they can block out up to 37dB of noise) and the tips we settled for in the end (the more rounded design) were more than comfortable enough for long listening sessions.But it’s not just the eartips you can experiment with here. Packed up in the sturdy, circular carry case is a small tube that looks like it might contain top-secret government information. It’s actually labelled ‘hardware kit’ and has a slim metal cylinder chained to it.This hardware kit actually contains two pairs of extra nozzles for the earbuds. These aren’t replacements for the ones currently fitted to the Aonic 5 should one snap or get damaged; each pair can alter the balance of the sound produced by the earbuds. It’s not a new concept and we’ve seen a few manufacturers offer this customisation over the years, but it’s the first time we’ve seen it on a pair of portable Shures.The Aonic 5 come with the ‘balanced’ nozzles already installed, with ‘warm’ and ‘bright’ nozzles provided in the tube. Want to swap them around? This is where the thin metal cylinder comes in. It’s actually a tool that fits into grooves in the metal collar at the bottom of each nozzle. Once it’s in place, simply unscrew the collar, switch nozzle and screw the collar back into place. There’s a certain knack to getting the tube and collar back in place, but once you’ve picked your preferred nozzles, it’s not something you’ll really need to do again.So how do the different nozzles fare, and which would we recommend using?‘Bright’ does exactly what it says on the tin – but for us, it overcooks things. The emphasis on the top end is quite marked with highs sounding more cutting and less pleasant, in our opinion. The strings and electric guitar in Mac Miller’s Cinderella sound quite brash and the track makes for uncomfortable listening.
