I’m getting closer to making a final decision on a pair of over-ears to wear when I commute - I’m actually slanting quite heavily towards the V-Moda Crossfade 2 Wireless Codex Edition (just gonna call it Codex from here on). However, one thought still bugs me. With the exception of headphones made by B&O and maybe others I’m not aware of, every other Bluetooth headphone of any size has their batteries sealed inside. That would mean that once the batteries fully die, they become either conventional wired headphones or complete junk depending on whether there’s a wired option. Since I take public transit and I’m on the streets often, I don’t want wires. So that means after whatever I buy dies and I want mostly Bluetooth, I would need to throw it out and get a new Bluetooth-enabled headphones. So given this disposable nature, would it make sense to just get burner cheap headphones, or still invest in a nice one and make it last?
