The headband on my 2-year-old 400se was flaking, and since I wasn't using it anyway due to the headband being a torture device, I decided to mod it lol.
I removed the old headband (irreversible) and ziptied hd600 nuggets on the metal band. The hd600 headband fits like a glove (same width as the 400se metal band). It looks kinda funny but it's better than not being used lol.
It works surprisingly well, but I might try other headbands later on since this aliexpress hd600 headband is also pretty stiff.
Sorry a noob trying to get into headphones . Have almost finalised the HE400se. Kindly suggest a budget amp+dac for these. I'll listen to mostly YT music on my gaming laptop (Asus ROG strix i7 10th gen) and my work laptop (HP Elitebook 360). Will also play Valorant, Dota 2 and a AAA here and there. My budget can't be more than 50 dollars. Thanks!
