Pros
Pro Rich, full sound
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.
Pro Fantastic sound isolation to block out unwanted noise
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.
Pro Comfortable once you get used to them
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.
Pro A lot of equipment
6 types of plugs (silicon/ foam: S/M/L).
Pro Outstanding build quality makes them long lasting
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.
Pro Thick, replaceable cable
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.
Pro Will stay in place in the ears
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.
Pro Two year limited warranty
Shure provides a warranty against defects in materials or manufacturing for two years.
Pro Amazing
Pro Balanced and clear sound
These headphones will sound great with a practically all genres of music. The highs are slightly rolled-off, but still present a good level of detail, so these headphones are not harsh. The mids are warm, while the bass is controlled instead of boomy.
Pro Extensive accessory bundle
The ATH-ANC23 offers good value for money due to the extras that you get. The accessory pack includes a carrying pouch, the active noise cancelling in-line control hub, an alkaline battery, an airplane adapter and a number of eartips, including foam ones, which provide a better seal and noise isolation than the standard silicone tips.
Pro Good active noise cancelling
The active noise canceling feature blocks out high and mid frequency noise quite well. Voices and environmental noise aren’t likely to interfere with your music. Loud, low-frequency noises like jet engines may still seep through though, so these are not the best for long flights.
Cons
Con Need some time getting used to
It may take some getting used to memory cables and there's a bit of a learning curve to putting the earphones in with memory eartips. At, first memory cables may seem a bit stiff, but after they're broken in, they're generally more comfortable than typical wires. There's even a wire sleeve that helps form the wire bundled with the earphones to help combat this issue. As for memory eartips--every time before putting them in your ear you have to press them together and then allow them to expand in your ear.
Con Inline mic and volume controls cost an extra $50
The supplied detachable cable does not have a mic or inline volume controls. They can be added by upgrading to the M+ cable.
Con The control unit to earpiece cable may be too short
If you are a tall person, you may have a problem positioning the large active noise cancelling module. The wire connecting the module to the earpieces is quite short. This can make it a little difficult to clip the module to your belt or pocket, which can get annoying.
Con Noise cancelling is not very effective on low-frequency noise
You may still clearly hear low-frequency noise, even with active noise cancelling turned on. The feature is effective on high and mid frequency noise, but not that well on low-frequency sounds. Loud engine noises may still mix in with your music.
