Bose SoundSport In Ear vs Shure SE215

Bass output is very good. It has good power yet at the same time is fast and punchy. It does not bloat the sound at all. The highs and mids are able to deliver a good level of detail that makes the sound quite lively. These will work best for bassy tracks, though rock, jazz, classical and pop will still sound enjoyable.

In stock form, these headphones have a relatively short cable. However, Bose includes an extension cable for extra reach. This can help to minimize the wire length that you have to deal with when going for a run or exercising.

The earbuds can resist small splashes of liquid or sweat. The hydrophobic cloth material wrapped around the headphones helps to minimize issues relating to moisture.

The specially designed Stay Hear ear tips have a wing design which helps to add grip to the earpieces when worn. This helps to ensure that the headphones will not easily get dislodged when on the move.

The ear tips are very soft and flexible. Combined with the ear bud design that does not jam into your ear canal, these are a joy to use in terms of comfort, even for extended periods.

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.
