1MORE Quad Driver IEM – Review

Once a proper seal is had, critical listening revealed a slight tightening of the bass over the Triple Driver, with a little less bloom and a little more refinement. The walking bassline across A Lovely Night from the La La Land soundtrack struck outward with more control and a decisive separation from the mids which led to even more total appeal to the already value-packed operation of 1MORE’s leading men. And while there are IEMs with even tighter bass on the market, none of them compete at a cost even remotely close to the Quad. In an even more rewarding move, the mids appeared to have gained a slight bump in realism and tonal fulfillment. This increased thickness in the mids comes across with a very clean, robust output, and is a very nice progression for the increased cost of the new budget flagship. Collectively the IEM retains good to great detail retrieval for the price, much on par with the overachieving Triple in this department. The treble strikes a very nice balance with the rest of the elements at play, providing plenty of reach without any screech. Its never too forward, which is an error that many lesser IEMs in this price category often fall prey to in an effort to conjure up the illusion of more resolution. The Quad plays nice across the entire range, with a slight bump over neutral in the low-end frequencies with a very closed off seal. This will vary slightly depending on the listeners choice of tip and other factors, but even the bouncy elevation shouldn’t prove overbearing to anyone familiar with these type of sonic executions.

So where does that leave us with the 1MORE’s Quad? For those looking to spend $99 on a pair of IEMs, our recommendation is still the Triple Driver. Its high performance and sonic retrieval meets our lofty expectations for an IEM, and does it all for under a Benjamin. The Quad throws a slight wrinkle into the equation. It keeps almost everything that makes the Triple great, but adds a little more presence to the mids and control to the lows, both improvements over the original. But it does so at double the cost. At $200 the overall impact could still easily be considered entry level pricing, a matter of rounding or something that can be easily managed by cooking for yourself for a few dinners. The equation to one’s ears is easily a improvement, and an experience that you likely get to rehash on many occasions during the morning commute or daily workout. I found myself reaching for the Quad given the opportunity, so first-time 1MORE owners may want to give the new guy a gander. For current Triple owners with the fever for upgrades the question is more nuanced, but the improvement is noticeable on a tangible level.

With both budget products in the field, 1MORE is really causing a disruptive state by bringing more definition, ergonomics and value pricing to the game that in recent years could really use the help. With high price propositions setting the bar for quality, its not only refreshing to see more of the magic hifi juice pulled down into the budget realm, but feels almost long overdue. With the value proposition question easily answered, the only remaining query left to ask is will 1MORE call their 6 driver IEM the “SEX”? Only time will tell.

    The quad is on this years acquisition hit parade.

    Every review I see of these reveals how little the improvement is compared to the Triples. And they’re quite far from the diminishing returns you get with TOTL gear. Sounds like a good model, but priced too high.

      Diminishing returns are the essence of an audiophile’s quest for the best sound.
