Introduction –

Once a subsidiary of Xiaomi, producer of the renowned Pistons earphone line, 1More has since branched off into its own, more premium audio brand. But as with many Asian manufacturers, 1More can get a little exuberant with their innovation, producing truly oddball products like their Capsule In-ear and even their very unorthodox E1008 earbud that I reviewed here. And while innovation is an imperative driving force in the industry, I would still argue that 1More’s strength lies within their more traditional products, their classic Piston derivatives, and their widely celebrated value champion, the Triple Driver Hybrid.

But 1More’s experience with smartphone manufacturer Xiaomi has definitely influenced their development strategy; 1More have begun refining their current products rather than further branching out through the innovative and unorthodox, something that I would consider just as important. And leading charge is 1More’s very striking Quad Driver In-ear, an evolution of the triple driver that came before. With an asking price of $200 USD ($300 AUD), the Quad Driver once again represents terrific value on a per-driver basis. But as always, specs and real world performance often live in complete isolation. Let’s see how the 1More Quad Drivers hold to up some of the best hybrid driver earphones on the market and whether their sophisticated driver array is refined enough to outperform more traditional earphones such as the Meeaudio Pinnacle P1 and Hifiman RE-600.

Disclaimer –

I would like to thank Ari from 1More very much for his fantastic communication and for providing me with the Quad Driver for the purpose of review. There is no monetary incentive for a positive review and despite receiving the earphones free of cost, I will attempt to be as objective as possible in my evaluation.

Accessories –

As with the E1008, the Quad Driver is impeccably packaged with punchy renders and a magnetic latch embossed with a brushed metal 1More emblem.

Within the box, 1More presents the buyer with a very systematic accessory layout that is both satisfying and comprehensive.

Perhaps most immediately noticeable is the extensive array of included ear tips. Due to the exceptionally large bore size of the earphones themselves, buyers are mostly delegated to the included ear tips though luckily, 1More include 9 pairs, 6 silicone, and 3 foam. The silicone tips, in particular, are very finely sized and I had no issue finding a tip that fit me. The fine sizing also allows slight tailoring of fitment depth, notably impacting soundstage and bass performance. Should buyers still struggle to achieve a proper seal, the included memory foam tips are of pleasing quality, slightly improving isolation and providing a more individualized fit.

In addition, the Quad Driver is outfit with a nice magnetic pleather hard case, a ¼ inch adaptor and a nice brushed metal shirt clip and airplane adapter. So not only are accessories copious, each is also of excellent quality, contributing to the Quad Driver’s air of premium quality.
