IEMs were originally used by musicians and true audiophiles, costing hundreds of dollars from big brands such as Shure, Westone, Ultimate Ears and so on. But in recent years, more lower-end IEMs for consumers started to emerge. Chinese IEM manufacturers also found their way into the hands of us consumers. We have two IEMs from Brainwavz – M1 and M2. How will they fare?

When people talk about IEMs in the past, they’re talking about high-end stuff that sometimes requires portable amplifications to power the driver(s) in them. But in recent years, big brands started to fill the gap between the high-end toys and basic earphones with entry-level to mid-range IEMs. Brands from China such as SoundMAGIC struck a chord with our local buyers offering surprising (often in a good way) performance and keeping our wallet happy. Now, we have Brainwavz entering the local market with the M1 and M2 in-ears.

Back in China, the Brainwavz M2 is the OEM version of the ViSang R03, and it is quite a hit amongst the Chinese. It gained much attention through word-of-mouth on the audiophiles forums around the globe.

Through the eyes (and ears) of a common folk, let’s see how will these IEMs performs but first, here are the specs of the two different models.
