Review: 1More Quad Driver – Bullet

1More Quad Driver

Today we’re looking at a very competitive offer from 1More, the award winning Quad driver IEMs.

Disclaimer: 1More supplied the Quad driver free of charge in exchange for an unbiased and honest review. 1More is not affiliated with Headfonia and not a site advertiser. Many thanks for the opportunity and generosity.

About 1More:

1More is an American brand that focuses on building high quality and affordable in ear monitors as well as headphones. They have received multiple awards for their products in the past.

They have been known to provide a great price to performance ratio with their products. 1More’s goal is to produce affordable head- and earphones that are seen as luxury. They don’t want to follow the trend of big prices and instead try to give their customers a very unique and fresh feeling of great quality audio without breaking the bank.

About Quad Driver:

The Quad driver is a hybrid in ear monitor that comes with a dynamic diamond like carbon driver for lows and three balanced armature drivers for mids and highs.

1More teamed up with Luca Bignardi, a Grammy award winning producer, to fine-tune the Quad driver. They have opted for a balanced sound with ultra-realistic sound stage. If they have succeeded at that, we will find out in the Sound section of the review. It’s nice to see 1More going the extra mile and asking for help from a professional to give their customers a satisfying sound.

When we’re looking at the tech sheet of the Quad, we will learn that it has a rated impedance of 32 Ohms and comes with a sensitivity of 99dB. That makes the Quad driver a relatively easy to drive monitor. I usually find hybrids to get better when you shoot more power into them.

To be fully compatible with the mainstream audio-head’s needs, 1More decided to put a microphone and in-line remote into the Quad. This is positioned near the right ear-piece.

The frequency range of the Quad driver is stated to go from 20Hz all the way up to 40kHz, making it applicable for the HiRes Logo by the Japan Audio Society. Which to me is more for marketing than it says about audio, but okay.

The Quad driver can be purchased for 149$ directly from 1More or one of their dealers on- and offline.

Package:

1More certainly has put a lot of thought into the packaging of their models. I’ve been wowed by the Triple driver already, and it’s no surprise that the Quad comes with the same packaging internals as its little brother.

You get a very nice and sturdy cardboard box that opens and closes magnetically. Flipped open you’ll see your new monitors and a broad selection of silicone and foam eartips, nine pairs in total to be precise. You’ll also get a very nice carrying case, a metal shirt-clip, a flight adapter and a 3.5mm to 6.35mm adapter. Underneath the eartips there’s a little more content: a user guide, a 1More sticker and a small flyer telling you more about other 1More products.

For the MSRP the Quad driver goes for the packaging sure is very convincing as you definitely get a premium feeling.

Build Quality:

From the first moment when you hold the Quad drivers in hand, you’ll notice the very high build quality of the housings. They’re made of aluminum and look like they can take a good beating, not that this would be advised.

Each ear-piece is finished in a gun-metal gray color and clearly marked with an L and R for the respective side. The nozzles are relatively short and angled at 45°. They do sit very comfortably in my ears and I have absolutely no issues with them.

Attached to each ear-piece is a metal tube that goes straight down. This I suppose works as a strain relief for the cable, which is made of oxygen free copper and measures about 1.2 metres. On the right side of the earphones you will find the in-line remote and microphone for controlling your smartphone (iOS and Android).

I’m not a big fan of the cable as it’s pretty springy and transports quite some friction noise, of course that last part can be solved by using the supplied shirt clip. The Quad driver is terminated to a 3.5mm 4-pole plug. Of course it’s not a balanced cable, the additional pole is for the microphone. The plug is right angled and also partially made of metal.

      I have been using them for a little more than a year and I couldn’t be happier with them. I agree with your review, and one thing I didn’t think about until I read it is the detachable cable detail, maybe because the default one is quite (very) good. If you can find an offer (I bought it at 120 euros) is a no brainer, all rounder IEM.
      P.S.: For my tastes it suits better with brighter sources, my every day rig is a Hidizs Sonata II attached to a Xiaomi Mi A2 and it’s an awesome combo. However in my Onkyo Granbeat may sound a little darker at times.

      Lovin’ this IEM despite the non-removable cable. One of the underrated ones out there, if you can get it for less than $150 then this is quite bang-for-buck

      I’m pretty sure 1More is a Chinese brand–with a big American corporate presence, of course.

      But they are nevertheless originally from China, founded by a guy called Gary Hsieh.
