The Razer Hammerhead Pro In-Ear Headset is an in-ear monitor (IEM) engineered from the ground up to set the standard in portable gaming audio. Machined out of aircraft grade aluminum, the Razer Hammerhead Pro embodies ultimate durability packaged in a lightweight, comfortable form factor.

Encased within each sleek, brushed shell is a high performance, precision-tuned 9mm neodymium driver. Paired with an optimized inner acoustics chamber in each shell, these in-ear monitors produce a sound signature that packs a strong bass while maintaining crystal clear mids and highs.

Supreme quality sound would be wasted if drowned out by stray, ambient noises. That is why the Razer Hammerhead Pro comes equipped with interchangeable ear-tips in 3 sizes, along with an optional pair of bi-flanges to provide superior sound isolation and bass response.

This exceptional audio solution also features an in-line omnidirectional microphone with one-touch phonecall control for crystal-clear, convenient voice communication with mobile devices on the go.

Topped off with a compact carrying case for portability, the Razer Hammerhead Pro epitomizes the way in-ear monitors should be experienced – with style, comfort and aural fidelity.

I'm using DA2013 and DABE.
Not much difference with the sensors though.

Lol im using a Logitech G400 at the same time too, it is same with the MX518 right?
If you like MX518, you will definitely like the DA too.
