Here is my mini-review of Penon IEM headphones (http://penonaudio.com/PENON-IEM).
I don't have to tell you about Penonaudio, most of the Head-fi visitors are well aware of their on-line store and ebay store (under bigbargainonline seller name). As a thank you to their customers, they are running a special deal on a pair of $100 IEMs where with a purchase of any other product in the store, members can get these headphones for a special price of $9.99.
It's truly an amazing deal to get a pair of headphones with a frequency response curve per below graph.
But as we all know, you gotta trust your ears than eyes, so here is my impressions after 30hrs of burn in.
First of all, they have a very solid build, alloy metal shell with a nice copper finish. Even a strain relief is an extension of the shell, and all metal. Cable is soft, tangle free, has a memory-free jacket, and as a matter of fact you can wear these either wire down or up. Also, I didn't hear any microphonics. Though, not exactly feather light, I still consider them to be light enough and the fitment was very comfortable. There is no chin slider, but it's still easy to manage it with behind the ear fitment to hold the wires down. The shell has two pinhole openings, at the nozzle (as I always find that one appropriate for a bass control) and at the end of the body (for soundstange and airness). Included accessories were S/M/L eartips and M/L double-flange tips. I saw someone post a picture with other set of eartips (white), so I'm not 100% sure if my set came with "standard" accessories selection.
In terms of sound, even after a burn in, I still find them v-shaped with enhanced low end. Overall sound is warm, detailed, more laid back. The bass extends pretty low with a nice sub-bass texture. Mid-bass has a nice slam, but I found the attack to be not as aggressive. The bass sounds a little more rounded. I also felt it spills a little bit into lower mids. Mids are detailed, clear, but feel recessed. It's not as obvious from FR graph, so perhaps overpowering bass enhances that effect. Treble has a very nice extension (definitely improved after burn in), and no hint of sibilance. This combination gives a very smooth, warm, laid back signature to a sound. Now, where these are absolute shine is in soundstage - is very wide and deep! I was definitely impressed with that.
As I have mentioned in the past, my sound preference is for a more balanced sound with brighter/leveled mids, but I still enjoyed the fun signature sound of these IEMs. I'm honestly not so sure about $99 price tag, but for $10 these represent an amazing value and perhaps will make a good addition to your collection or as a present to someone who enjoys extra bass in their sound!
KC06A and VSD3S set a bar pretty high, for my personal taste. If Ostry can come up with a removable cable model to use standard MMCX (not the "proprietary" mmcx used in VSD3S), these probably would be my IDEAL iems. Until then, I will have to use their stethoscope cable jacket lol!!! The same with VSD3S, why use a connector that can't be backward compatible with a ton of replacement cables where for $30-$40 I can get a decent silver-plated one to brighten the sound :) Other than that, those two are still at the top of my list, review is coming up!
I'm adding this here, and not sure if this mod has been advertised, so...For those who might be frustrated with the sound of your Xaiomi Pistons 2.0, I just modded them by removing the screen, gutting the filters on the inside, and adding a very small square of ear tip foam (2cm up and down), and inserting it all the way in the back in the well where the filter sat. The treble gets clearer, the bass tightens up, and the sound is smoother and more open. Still not smooth like Tenore smooth, but still..makes these a way better listen. A good fun listen.
Warning: Spoiler! (Click to show)
On the second pic, though hard to see, the foam is pushed all the way to the back, covering the sound vent hole at the rear well.
So you've put damping foam in both back and front ports? Can you replace the grille, or is this a permanent mod?
@twister6, which do you prefer most? Just to lay down, close eyes in the dark, and lose yourself? Ostry KC06A, Audio Technica IM03, or Zero Audio Doppio?
I will have to get back to you on this one. Listening to KC06/KC06A now after more burn in hours. I might have to flip-flop my opinion with a preference more toward KC06. After closer listening, KC06A is more v-shaped than I expected (with boosted sub-bass), while KC06 is like a love-child of RE400 and Tenores (reference sig) where you get a great bass quality with additional quantity to give it more body and detailed mids to make vocals sound very natural, detailed, and smooth. RE400 lacks brightness for my taste, and my reference sig Tenores lack body due to anemic low frequency (plus I have been getting a bit annoyed by their inconsistent performance). I haven't listen to Doppio's in awhile, but those had reference sound sig, maybe a little too bright and not as much bass (need to go back to re-evaluate it). But Doppios built quality is amazing!!! IM03 - I have a psychological factor where something that cost 6x as much as these other giant killers doesn't perform 6x better :) I will be doing more listening in the next few days, time permitting, and will update my opinion as I go along.
My Pistons mods is documented somewhere in that thread, with pictures. After I removed the grill and the filter, I closed the nozzle with RE400 stick-on filter - to keep it clean and to tame down high frequencies ;) Worked really good!!!
