I have Audiocular D07 and Wyvern Pro earphones, but I am experiencing connectivity or sound issues (a hissing sound) with my S25 Ultra. I tried the Wyvern Pro on my other devices, and they worked great, so it is definitely a connectivity issue with my DAC (Audiocular D07) and my S25 Ultra. I am looking for a DAC/splitter that works with the S25 Ultra, as nothing seems to work for me. Especially for gaming (FPS games like BGMI/PUBG) and hi-fi music.
The hiss sound on silence is a normal thing for most portable DACs, you won't hear the hiss when the sound is playing on the phone. I have both D07 and KZ AM01, both behave the same. You can try some direct type c earphones like from JBL as well, might work better for you.
That's just another sound covering it, but if you listen closely, you will still hear it under the running sound, though a little less than before. The hissing is permanent; other sounds can cover it until they play on top of the hissing.
Although I can IGNORE the hissing, but the connectivity issue persists. My earphones' left side gets louder, and the right one gets too low. If I reset the DAC settings from the developer options, it fixes the sound issue and balances it until I reconnect the DAC, but this causes another issue: the earphone's microphone stops working, and nothing I say goes through. So it's definitely a connectivity issue with the DAC and how the S25 Ultra handles it.
I just want to know what people are using with the S25 Ultra for gaming and everything else.
There's something wrong with your DAC cuz in my case that hissing sound only comes for around a second or two when the music plays, also no disconnection issues at all. Get it replaced ASAP.
