I do not recommend the Penon Quattro. They have a warm sound with an analog and organic timbre. In general, it is a niche audio brand specifically for people looking for an IEM specialized in certain audio aspects. It is better to try other all-terrain models such as the Penon Fan3s, ISN Neo5, ISN H60.👀
r/iems • Why is penon/isn such an undervalued brand? ->Hey, these things (Penon Quattro) are magically improving. I also swapped the Tangzu Sincai balanced eartips for the stock white and red ones, and the sound and dynamics opened up much better. And of course, I put Tangzu Sincai balanced eartips on the ISN Neo5s, and the soundstage increased. Thanks, and please let me know about the ISN EST80 when it arrives. I'm thinking about financing options. The yellow ISN EST80 has me completely insane.🤑🤑💣
r/iems • Why is penon/isn such an undervalued brand? ->Ooh u got the Quattro !!! I’m glad I told you how good it was !!!! Great minds think alike ! We like the same sound signatures ! And you’re totally right ! All that other garbage don’t even sound good ! It’s boring and plain all of it is ! Shit is overrated ! Hyped and isn’t great at all ! If it doesn’t sound like Penon or ISN . All pass ! My other fav is Globe and Dome ! I just ordered EST80 also !!
r/iems • Why is penon/isn such an undervalued brand? ->The Quattro is power hungry ! It’s a lot of power ! I use a 500mw dac and I have to turn it up to 85 too . It’s very analog sounding and dynamic ! The sound signature is like a thick Analog polished clear coated sheen to it ! Nobody believes in burn in on here but the Quattro needed some weeks of burn in ! The DDs needs to settle ! Then it’s way better !
r/iems • Why is penon/isn such an undervalued brand? ->Yea iv tried several different cables on Quattro and the stock graphene is the best !
r/iems • Why is penon/isn such an undervalued brand? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
