What other tubes are compatible with this headphone amp?

So I have a PC38x headset that I bought a few years back. I moved away from home for work, and left the headset there with my gaming PC. I used it maybe 2 or 3 times before I left, and it always had the problem of it cutting out in my right ear phone. It makes like a crackling noise like something is loose, and then cuts out the audio entirely. Sometimes it works for a few minutes, but inevitably cuts out on the right side again. I am wondering if there is a fix? Or could I be shipped a new one?

Please someone here help buy a headphone for my use case- listen mostly Indian music ( old and new Bollywood songs ) . play them on my iPhone. So need to be wireless. must be light and comfortable for small ears and 3-4 hours of listening. noise canceling is not important. budget is around $150. i am not audiophile by any means and do not understand much of the jargon. Just want something that sounds good and is comfortable on my ears while I work from home. thank you all.

Hello, I am wondering if anybody has any experience contacting E-MU support, sending them headphones for repair, or getting them back fixed. Can anybody share any experience? I have been emailing them for a while now, but nobody has responded. Thank you.

Finally got my hands on the pc38x. I mostly wanted to try this headset because of all the good things i heard about it. Out of the box i wasn’t really impressed. My 50 dollar astros were just as loud if not louder. After setting up an EQ on dolby access i got them sounding a little better. But one thing that really bothers me is the volume dial on the headset. When i turn it all the way down there’s so much audio still coming through, like the headset is turned up 10-20%. Is this normal?

i own a Drop + EPOS PC38X Gaming Headset and i need a new cable that connects the headset to the computer. i dont know what its called and i cant work out what to look for on amazon etc. could someone please help me with this
