Shure SE215 vs Zeus Outdoor

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.

The Zeus Outdoor combines Bluetooth connectivity, water resistance and active noise cancelling with a thumpy sound signature. These are fun to listen to, convenient to use and can resist damage due to moisture at a good price.

These connect to a sound source via Bluetooth, so only a very short cable connects the two earpieces. This can help improve your mobility and minimize cable-related distractions.

Ambient sound leaking in to your music can be drastically reduced by the active noise cancelling feature. You can better focus on your music, as well as your run/work out.

These have an IPX7 rating which makes them water resistant so they can be used while running, even when it's raining. Do take note that submerging these headphones beyond a certain depth will negate their water resistance.

Bass hits are powerful and forward, which should complement the upbeat and thumping music that most people listen to when working out. Highs and mids are recessed though, so these are best for bass lovers.

Ear hooks are attached to the earpieces which provide extra grip over your ears, so these will not fall off easily. The short connecting cable also minimizes the weight that may pull down on the earpieces .

You get a number of silicone ear tips in different sizes, some foam ear tips as well as a carrying case.

These can last up to 8 hours of continuous music playback.
