Review: Brainwavz M2 in-ear headphones and Krudul Duo holder


Among the incredible range of headphones we have been plugging away with testing in our audio lab and everywhere else around the building, is Brainwavz’s M2 in-ear headphones. This marks the second pair of headphones we have tested coming from Brainwavz, and first one that falls under the $100 price point.

The M2 headphones are more of a wired in-ear solution for those not wanting to throw all their money at something all at once. We find these to fall within the range of an entry-level solution, as well as a great option for those hard of hearing.

To start off, the design of the headphones is quite simple. By simple, I mean they are a light in weight, with a small body style to the buds and thin cable footprint. The wires themselves feature a small gauge approach, twisted, and very lightly insulated. They also keep a strong memory, so it will take a little heat to straighten them out, once removed from the package for the first time (in case you are OCD about this as I am).

The body of each bud offers a simple footprint, which makes them easy to store and light in weight–but, leaves little room to brag about what’s inside driving them (of course). The materials are all plastic, and feature a silver and black appearance.

They don’t seem like much (mostly because there really isn’t a lot to them), but they do appear to be durable, as we unintentionally roughed them up a little during our usage. Despite that, there was no damage to the cable, and the buds continued to operate just fine.

Of course, sound quality is the important point to focus on, and we seemed to get what was expected based on the small/light design. These headphones have a solid focus on highs in their frequency spread. This is why we highlighted the fact that these would be a great option for those hard of hearing. They are indeed a little bright, so you have to be looking for this kind of sound. They would be good for listening to vocals for isolating certain qualities in a track, or using them for in-ear monitors during a live or recorded performance (if all you want to hear is your voice). There is no muddiness to the highs, which allows them to shine in this area.

The mids are slightly above the average range of a discount bin pair of headphones, also without muddiness. This helps add slightly to the clarity of what you are listening to. Bass (lows) however, is about average–although you have to reach for it. By reach for it, I mean you have to use the largest of the tips to get the best seal you possibly can. They say online that they offer “deep bass”, but this can be argued all day, as I have yet to discover anything deep. We also found that the largest tips included still didn’t do much for us. Most of us had to slide them into our ears like ear plugs, in order to get a tight enough fit. Of course, that doesn’t last forever.

They do come with a lot of tips. There are a total of 7 pairs to choose from (one of which is Comply foam and the rest silicone). You might find the Comply option to work best, in order to get a tight enough fit. Although they supply a wonderful amount of tips to choose from, we felt that the largest pair was a little on the “not large enough” side.

Last but not least, we found there to be a little more cable noise than we would prefer to experience while wearing them (this is when the cable drags across your clothes or itself, and resonates sound to the ears).

Along with the many tips, there is a nice hard-case solution to store the headphones in. There are two mesh pockets so that you can easily include some of the accessories if you’d like. They also include a small clip to clip the wire to your clothes with, as well as a velcro strap to wrap around the headphones once you have them coiled (or wadded up……take your pick).


We also got to play with their Krudul Duo earphone hanger. A pack that actually comes with two different options inside, one for the back of your/a monitor, and one for hanging your earphones vertically, just about anywhere you can stick it to.

This is an optional accessory that Brainwavz sells and does not come with the headphones (nor do they come with any headphones). They are simply a hanging solution, if you so choose to make use of installing one in your gaming or listening area. We decided to include them in today’s story, so that they don’t get left out.

They feature a die cast aluminum design, and most definitely deliver a quite durable build to them because of this. They don’t weigh much at all, as sport 3M tape on the back so they can be effectively mounted to just about any flat (hard) surface.

For quality and being priced less than $10, we decided to give them their own score separately, of 9/10. Great construction, good choice in adhesive solution and they work for what they are intended for. The missing point in the score resulted from our not being able to find a reason to use them anywhere. An accessory like this definitely depends on a small niche and unique solution discovery.

Personally, I can find a million ways of using these hooks for something. Sadly, none of them would include hanging a pair of earphones somewhere.

Our Conclusion (back to the headphones)

They are a light pair of headphones (earphones), simply in design and durable against stress. They work great for listening to highs, yet lack on the lows. The mids are nice, but are kind of overwhelmed by the highs. Long story short, we found them to be a little pricey since we had a number of complaints about their performance. They don’t feel like a $59.99+ pair of headphones. They do come with a lot of great accessories, but feel as though they need better a balance to their range (and cable noise). This would help justify the price (or, bring the price down about $20-$25. As mentioned, they are great if you are hard of hearing, or simply want a more affordable pair of IEM for vocals.
