We all know that adding more to an audio product doesn't necessarily make it better. However, in the case of the 1MORE Quad Driver in-ear headphones, more is most definitely much, much better.

The Quad Drivers contain three balanced armature drivers and one diamond-like carbon driver. This combination delivers best-in-class audio quality across the spectrum. 

Interestingly, 1MORE launched the cheaper 1MORE Triple Driver headphones at the same time. Although they’re more affordable, and a much better bargain than the Quad Driver at nearly half the price, if you can push your budget just a bit further you can bag yourself a better built headphone, as well as much better sound. 

With a $199 (£200, about AU$335) price tag, the 1MORE Quad Driver headphones certainly aren’t cheap. But they’re actually good value for money compared to the competition in the same price range – they absolutely stand up against the best in-ear headphones.

That means if you’re on the hunt for a great pair of headphones that sound as luxurious as they feel, you’ll struggle to find anything that matches the high standards of 1MORE Quad Driver in-ear headphones.

The moment you open the box, the 1MORE Quad Drivers impress with both their packaging and build quality. The earbuds feel like they’re milled from a solid block of aluminum. Even the remote and 3.5mm L-connector are made from aluminum and feel like they can withstand being run over by a car. 

The earbuds are quite large but still fit comfortably in our ears. 1MORE packs a ton of different earbud tips to try and it’s a good idea to experiment with the to get the best seal. Without a proper seal, bass response will suffer.

On the right earbud cable you’ll find a three-button remote that works with Android and iOS device to control volume, playback and to activate your voice assistant of choice. This may seem like an overrated feature but many headphones work with either device but not both. For example, the V-Moda Forza’s controls only work with Android devices but not iOS. 

The cable of the 1MORE Quad Driver is tangle-resistant but that doesn’t mean you can’t tangle them. They simply resist bending with its Kevlar coating, which helps make the headphones feel even more robust. The cable is similar in construction to the excellent Klipsch Reference X6i

Included in the box is a very nice faux-leather hard case with a magnetic clasp, a 3.5mm-to-6.35mm adapter to use with desktop amplifiers, a shirt clip, airline adapter and a ton of silicone and foam tips. We found the included foam tips to be too shallow to create a good seal but thankfully, the included silicone tips are excellent.

Throughout our test, nothing about the 1MORE Quad Driver in-ear headphones jumped out at us. But listening to other pairs of in-ear headphones left us impressed by the 1MORE’s balance, soundstage and voicing. 

Fans of the Sennheiser HD600 will love the 1MORE Quad Driver. Like the Sennheiser, the sound presentation is slightly dark and laid back. This creates an effect of sitting in the middle of a concert hall instead of being in the front row. That being said, fans of a more dramatic, front row presentation may not enjoy the voicing of the Quad Driver. 

In terms of tonal balance, the 1MORE Quad Drivers are wonderfully balanced. Highs have nice extension but lack the sparkle of more forward earbuds like the Beyerdyamic iDX 200 iE. That's not a bad thing necessarily as this means you can listen to the 1MORE for hours without suffering from audio fatigue.

The mids are the standout of the 1MORE with a lush, honey-like presentation. Female vocalists like Norah Jones just sound so smooth and detailed. There’s a slight mid-bass bump to give a slightly warm presentation, which works to help poorly mastered songs sound bearable. 

Bass is tight and features great extension and impact. The 1MORE Quad Drivers do an excellent job of sounding great with just about every genre of music from classical to rap. 


While $200 is a lot of money, in our books the 1MORE Quad Driver in-ear headphones are worth every penny. 1MORE hit it out of the park with this flagship pair of in-ear headphones, which combines balanced sound build quality, smartphone compatibility and price. In short, these in-ear headphones will make mobile audiophiles very happy. 

The only reservation that we have is that the Quad Drivers face tough competition from 1MORE’s cheaper Triple Driver sibling, which costs half the price and feature highly on our pick of the best in-ear headphones.

In terms of value, the 1MORE Triple Driver headphones are the winner but for those who want just a bit better build and more detailed sound, the 1MORE Quad Driver headphones are worth the extra money.
