Shure SE215 vs Brainwavz M2

Bass is emphasized so there is a good bit of thump while staying controlled. Mids are rich, highs avoid sibilance, though they're a bit rolled off.
Soundstage is okay--instruments are separated out enough for them to not sound like they're all coming from the same place, but it's not particularly wide.

The memory foam eartips mold to your ear to provide amazing sound isolation, though there's a bit of a learning curve to using them. You have to press them together before putting them in and then allow them to expand in your ear. Once expanded they will take the shape of your ear and that way provide excellent noise isolation.

The earphones also come with silicon tips which are easier to use than the foam ones and also last longer.

The SE215 earphones have a negative profile, optimized nozzle angle, over-ear fit and memory eartips that ensure the earphones stay in place comfortably regardless of situation. You can even lie on your side with them.

6 types of plugs (silicon/ foam: S/M/L).

SE215 earbuds use tough plastic earpiece shells, have a robust kevlar-reinforced cable, a sturdy Y-splitter that's difficult to bend and an L-shaped plug that adds additional strain relief. They won't break if you snag them, drop them or sit on them. They're also completely sweat proof so you can use them while working out without having to worry about damaging them. They're durable enough for professional stage use for which they were specifically designed for.

The SE215's 6.4-ft. cable is very thick, and further reinforced at the left/right split point. Reviews confirm the durability benefits of its heavy-duty design. If it ever does break, the cable is built to detach safely from the earpieces, allowing replacement.

The optimized angle of the earbuds, over-ear fit, and memory ear tips ensure that the earphones stay in place comfortably regardless of situation. These are also sweat-proof, so they're a great option for active use.

Shure provides a warranty against defects in materials or manufacturing for two years.

Despite being made out of metal, these in-ears are still fairly lightweight, so wearing them for long periods shouldn't be a problem. The included ear tips are also quite soft, providing good cushioning and seal.

The highs of these headphones are not too sparkly or airy, yet still has good detail. This results in a smoother sound. Mids are forward and clear, while the bass has good depth without creeping up on the mids.

Overall, these headphones are quite fun to listen to and can work with pop, rock, hip-hop and even metal. These are not the best though if you tend to listen to music with a lot of detail and intricate parts like jazz or classical as these do not offer a high level of detail reproduction.

The M2's cable is braided and covered with a sleeving material, making it significantly more durable than other cables. It also makes it extra resistant to tangling.

The ear pieces are made out of metal and have great fit and finish. Not only does this make them look great, but also gives them a premium feel.

With the M2, you get 2 types of ear tips with three sizes each, a shirt clip to prevent the cable from moving around when worn and ear cable guides to help keep the headphones in place.
