Was excited to give the Eeers a try as it would be nice to have a smaller package headset to travel with. These are custom fitted earphones, here is the product website http://sculptedeers.com/ Purchased mine in ATL from Airport Wireless Total cost was $213.99 The entire process took about 40 minutes. This was longer than normal as I had to do it twice. They staff opened the package and instructed me to "lube" the ear pieces with the provided micro water based lubricant bottle. Next you place the device over your head (looks like an enlarged headset) and insert the plugs into your ear. Staff then adjusted the head strap and verbally review the process of what I will hear and feel. The staff was excellent in this area. The process starts with the sound of a soda can being opened and then it's 4 minutes of silence and no motion. A 4 minute video explains what is happening as well as providing care and handling for your new Eers. Airport Wireless staff were extremely helpful and when I had a problem with the right ear fit, they quickly opened a new box and said let’s try again. Second time went much better and I had a better fit and sound was good. Sound quality is good with music, Podcasts and TV shows, but ambient noise is still there and distracting. These are not noise canceling. This is only day 1 and my initial thoughts are to go back to my Bose. I used on a short 1.5 hour flight from ATL to MIA. I took them off halfway through the flight due to discomfort. The FAQ in the user manual does state "Custom buds will be the most comfortable earbuds you have ever owned, but you will need to break them in, just like a new pair or shoes. For the first week, wear your earphones for only a short period and gradually extend the time." The Airport Wireless staff as well as the user manual (yea, I actually read it) tell you to wet the earbuds prior to use. The manual says "Simply put the lubricant (or some water droplets) on your finger to wet your ear canal prior to insertion." So you will need to carry the micro bottle of water based lubricant or I guess use spit To me, the Bose QuietComfort 15 have better sound quality and feel better. Plus I don't have to lube them up to use. I would be interested to hear from others who have the Eers and their impression.
