Beyerdynamic Xelento!

Burn in doesnt exist in DD and BA drivers. Xelentos will not change even after 100000 h, they will sound like they sound stright out of the box.
This ⏫

@Mungam, best you can do is tip roll. For me, personally, the previously mentioned Divinus Velvet Wide Bore pair really well with the Xelento gen. 2.

Are you sure about that? The FDX are dynamic drivers, and they need to burn in for sure...
IM 110% SURE so dont bother burning in DDs or BAs. Some even say that planars dont require any burn in either.
So no burn in in headphones, iems, sources etc, just forget about it and start playing with tips because they are the most important factor in making a more significant adjustments in the tuning.

Who is saying that? Even FiiO recommends to burn in their FDX? Is there a statement from Beyerdynamic?

I am very sure about burning in sources. It is measurable, e.g. capacitors need a burn in to be within specs. And capacitors usually have a very big impact on sound quality.
Don't get me wrong, I am not one of the "everything needs to be burned in" guys, or "the electrons in that cable flow better in that direction". What I want are measurable results, or if that is not possible, then at least a good explanation why it is necessary or not.

Different tips will of course have a very big impact on the sound. But I am not sure if they can improve just the problems I have right now without changing other things as well. It seems I have to test the IE900, too, but I am afraid that I won't like the highs.

I don't want to go down this route and discuss this topic, but the reason why FIIO and other companies mention burn-in is to get you to not return products right away. In 99.9% of cases the only thing that happens is that your brain gets used to the sound and tuning of the new audiophile products you got.

Burn in is like a taboo discussion here, I see.

While we're on the topic, I just want to share a bit experience regarding my custom IEM, which I made with my friend, that had no bass from initial 10 secs impression till it is bass heavy, and I do make sure it is not a brain burn in, since it is measurable.

I think some company do test their product intensively so it can counted as a burn in itself, which made their IEM doesn't have any effect from our burn in progress, but some do have it's effect.

Personally, the brand itself always make sure to say "you have to burn it in first" just to make your brain adjusted to it first, however minuscule it is.
But if it's an argument regarding is burn in real or not? It's a simple yes, I tested it myself, but if the question would burn it in matter after you buy the product? It's another thing to be discussed.

Unfortunately it is not that easy. Of course there are companies who tell you to burn in so that your brain gets used to it.
But on the other hand, it makes sense for several other things. Sometimes it is measurable, then it is easy, but sometimes it is not, and then the discussion starts.
What I always like is, when someone can convince me with some physics, why it makes sense or not.

What I did with my FDX was: Testing them A-B with another another IEM, and of course, with the same measured loudness within 0.2 dB. Then burned in for 50 hours without listening, and repeating the test with the same tracks and volume. Then it was very easy to hear the difference of the burn in process. Of course it is still subjective and just my opinion, but that is what I can do at home with my equipment. I haven't started that process with the Xelentos, that is why I asked.

That's not a real test, is it? It's just your subjective opinion that can be heavily affected by confirmation bias... Up to now, I haven't seen a real scientific test showing better/different performance of an IEM after 20/50/80 hours of "burn-in". Just my 2 cents, as I said I really do not want to get into this discussion. 🙂

Yes, you are absolutely right. It is my subjective opinion. It is the same opinion when you try new gear, if you like it or not. If you do, you are happy.
I don't want to convince anyone. I just think it should always be science-based, if possible. And the *tests* should be done following some standards, so it is reproducible.
I start asking when someone says this or that is true or not. Then I would like to know where that information comes from.

Ok, after 24 hours of burn in they sound much better...no, just kidding, in this case I have to admit that I don't hear a difference, I am just getting used to them.

Can someone recommend tips which would reduce the upper Mid Bass / Lower Midrange a bit? I switched now to one step larger tips, that reduces the bass a bit, but they don't fit very well.

What cables are you using? I tired some cable I have here, but with them it is hard to get a good seal on the tips.

Many thanks.

Ok, now I really like the sound of the Xelento as it is. Took a bit of time for me.

The only thing what I would like to change is the cable. I'd be happy for any recommendation. Thank you.
What eartips are you using?
While trying the stock ones and also the cable, the sound was too bright and a bit dry for me.
I found the Final Audio type E eartips being the best until now and I've just switched to a copper cable from Null Audio (Epsilon MKII) 2 days ago, hopping for a slightly less bright sound.
The cable is just ok but for the price I was expecting more.
I feel the bass is lacking some depth, hope to see some improvements next days.

I am still using the stock eartips. I tried some tips I have around, but will certainly try the Final Audio Type E eartips you recommend, thank you for that.
I was now able to use the Fiio cable that came with the FDX (LC-RE Pro cable) with a good seal: It is a 33% Silver / 33% Copper / 33% Gold cable and sounds quite good. It is not too thick, very neutral, but I really have to test it long term.

I don't want to go into a cable-sound discussion.
I don't like the original cable, I find it to thin and often it does not stay behind the ear. The FiiO cable is much better in that resect, and still not too thick. But it is harder to get a good seal of the ear tip due to the bigger connector on the FiiO.
For fun I just measured both 4.4mm cables: The original has an overall resistance of approx. 1.4-1.5 Ohms , the FiiO has approx. 0.5 Ohms. So that is 1 Ohm difference. We have to consider that when we hunt for a low output impedance of our amplifiers.
Has someone already measured the impedance of the Xelento in the hearable frequency range? I have not found anything on the web.
