Sorry this is true,
The issue is that you cant replace the battery so when it dies (in 2-3 years time) you end up with a very expensive pair Bose IE2 audio headphones with a paperweight battery pack on the end of the connector.
Sorry i know it was something to do with the battery when i was assessing to get them or not.
I dont know generally how long people hold onto headphones and if 3 years is a reasonable time but for $400 i would want them to last for a long time and be able to have the option to switch out the battery even if i didnt want to use them anymore.
