Treble. The treble on the IE2’s can become distorted and grainy after awhile, while the SE 215’s treble is sharp, crisp, and alive. The 215’s have some of the liveliest treble I’ve ever heard out of any listening device.
Fit. There’s a bit of a learning curve in wearing the 215’s at first. Once you understand how they work, the sound becomes that much better. Put them in right and get an amazing sound. Get it wrong and you’ll wonder why you paid for them. Lol. The Bose IE2’s tend to fall out easily, especially when moving around, running, etc. So the IE2’s are easier to put in your ears, but may not actually result in a good long term fit.
Replaceable cable. The 215’s come with a replaceable cable, while the IE2 does not.
Sound isolation. The 215’s have better sound isolation because of that snug fit that we discussed.
Wires and such. The IE2’s wire tends to cut out on one side. This is likely the fault of the driver, or the wires snapping near the driver housing. The cables on the S215 seem very rugged and sturdy by contrast.
Weight. The IE2 weighs 0.65 oz. vs. 1.1 oz. for the SE215.
Warranty. The IE2 has a parts and labor warranty of 1 year vs. 2 years for the SE215.
Overall sound. The overall character of the SE 215’s is more lush, with better instrument separation. They just have a tighter, more well defined sound. It’s a loud, exciting sound but also remains controlled and never becomes too loose or flabby.
Plug. The Bose IE2 has an L-shaped plug vs. the straight plug for the SE 215.
Inline remote. The IE2 has an inline remote while the SE 215 does not.
Sleeves. The IE2 comes with 2 extra sets of ear-bud tips while the SE 215 comes with 6 total.
Cable length. The IE2’s is 1.2m vs. 1.62m for the SE 215.
I bought a pair of the SE 215’s for my mom and they are fabulous IEM’s. The sound is extremely crisp, transparent, and exciting. The bass slams pretty hard, but it’s controlled, tight, and has plenty of impact.
I would recommend the 215 over the IE2 for the reasons mentioned above. Interested in learning more about them?
