1MORE Quad Driver E1010 IEM Review

Rating: 9.0.

While we have previously reviewed the 1MORE Triple Driver H1707 over-ear headphones, 1MORE is actually best known for its in-ear monitors (IEMs). It is the company's flagship IEM that we assess today – the Quad Driver E1010. With a MSRP of £149.99 here in the UK, these aren't that expensive – relatively speaking, of course – but we would still expect a very solid earphone for the price, so what does the Quad Driver offer? Let's find out.

As you would expect from a flagship product, the 1MORE Quad Driver E1010 has a number of noteworthy features. Foremost among these is the quad driver nature of each earbud – each bud sports 3x balanced armatures and 1x dynamic driver, with the dynamic driver handling the low and mid-range frequencies, while the three armatures are responsible for the high and ‘ultra-high' frequencies, as 1MORE puts it.

The earphones also use plenty of aluminium in the build, while the cable is a 99.99% oxygen-free copper wire with a Kevlar wrapped core. They certainly sound good on paper, but what is the actual experience day-to-day? We put the Quad Driver to the test to find out.
