The Etymotic Er6i is an excellent earphone. Based on many many reviews from people prior and during my purchase, I have found their complaints to be understandable. It is "weak" on the bass and its thumpiness, if it was a category, could not be spoken in the same breath as say the Sennheiser CX300s, which were the earphones I used prior to trying these out; however, it is extremely accurate and is meant to be for someone who wishes to hear what the producer had in mind in the production of the song. The bass, is by no means, weak - it is when people are used to hearing "loud thumpy bass" and equate that with "sound quality". Thumpy bass does not necessarily equal good earphones. It takes some time for your ears to adjust this new adjustment FOR SURE.
Strongs:
- Very clear and enhancement of song listening experience
- Strong yet natural sounding trebles, equaled with an acceptable amount of bass
- Superior Noise Isolation/Insulation - you'll not be able to hear nearby people talking and the noise from the bus will be dramatically reduced, especially if you're sitting in the middle of the bus
- Comes with a pouch for your earphones so they don't get damaged
- A shirt clip so that the wires will not jump up and down while you're doing a physically exhaustive task such as running.
- From what I've read, Etymotic provides EXCELLENT service - they will send items to you to help you out (i.e. different sized earbuds if you can't find the proper fit) or if your Etymotics for some reason do not work, you can ask them to take a look for you (and they'll be very happy to do so AND replace it)
Weaknesses:
- "Lack of bass" - if you came off the CX300s and listened to these afterward, you'll be really disappointed in this department
- Superior Isolation - very dangerous on the road - this is NOT my complaint; I purposely chose this as a specific feature at the cost of safety. But for some people, they'll find this feature far too effective for their own good. Use common sense.
- Earbuds, depending on your earcanals, may not fit. However, Etymotic Research will do a good job of providing sample eartips for you to try. It will take time (not that long) for you to master the insertion of these buds
Final Decision: An EXCELLENT earphone at an EXCELLENT PRICE. I paid near the exact retail of these phones but it's still worth it even though the overpayment might have been 50-60 dollars more. Etymotic earphones ARE worth it.
Song Genres most appropriate for this: Songs that don't require too much bass. Classical songs could arguably be the most ideal choice listening, although R&B and some Rock songs sound more than acceptable. The instrumentals in all these songs could be thoroughly heard - ESPECIALLY the classical songs. BEAUTIFUL.
