And how long will it be very good? Bluetooth headphones seem to represent a huge change in standards of support.
To use an example from the same company, I have an HD 280 pro, which I bought well over a decade ago. I can go on Sennheiser's website, and buy replacement ear cushions or replacement head band pads. It looks like the replacement cable is no longer easily available, but it was sold for a number of years, and replacing the proprietary cable (criticized in many reviews at the time) with a standard one (or a jack) is not that hard.
For a new example, all parts that might break outside the core of my Etymotic ER4SRs have replacement parts, and all can be very easily replaced.
A search for replacement batteries for the HD 4.40BT, on the other hand, comes up with nothing except the user manual's admonition that battery replacement by anyone other than Sennheiser will void the entire warranty (something that seems likely to be illegal in many places), and noting that instructions are available (outside of warranty) only for "qualified service centers." There are instructions in the manual about replacing the ear pads, but ear pads don't seem to show up on Sennheiser's website, which is rather surprising, considering that a search for the 2000s-era 280s easily comes up with replacements; wider searches come up only with poorly-reviewed cheap third party replacements. There is a replacement cable, but then again, it's just a standard cable. Replacement batteries don't appear to be available anywhere.
So when the battery starts dying, are you expected to throw them away? Use them until you become frustrated enough to buy new ones, and throw the otherwise decent ones away? Hope that Sennheiser will replace the battery for less than the price of new headphones?
