Do you recommend these -- how are the measurements? Oluv was raving about them in his unboxing vid. I've stopped spending this kind of money on headphones. If the Elex is actually a standout I may indulge.
Recommendations on headphones are hard because they're so personal. Here is a subjective comparison of the Elex to the HD58X that I wrote on the basis of a relatively brief time with the Elex.

https://www.headphones.com/blogs/news/massdrop-x-sennheiser-hd58x-vs-focal-elex-comparison

In measurements the Elex shows better subbass extension and slightly lower distortion than the HD58X, but less smooth frequency response and what I would consider slightly brighter than neutral treble. Something to keep in mind is that Drop no longer seems to offer official Elex replacement earpads so you'd have to go with Focal Clear pads. Those might look weird on a black headphone, but more importantly they cost $200 which I find outrageous.

Yes ... I remember that.

But also, as I recall, it was not the relatively few experimental DIY efforts that bothered KEF, rather KEF found several small manufacturers (I don't have details of who or where) building some loudspeakers advertised for commercial sale with drivers bought from KEF's replacement parts inventories, and it was that which KEF wanted stopped...

BTW, first step to an economic audiophile/boutique update of my modded KEF Q100 crossover:

Tony Gee recommends the expensive and new Miflex KPCU-01. I will try as bypass.

When I bypassed with the cheap styroflex/polystyrene the sound at HF improved. That is why I want to try Miflex KPCU first. I was skeptical that I tried to spend the least. I can not deny the improvement.

As the Mills resistors are not as expensive as the Mundorf Supreme that I chose years ago but I did not buy, I decided to include them.

The great improvement was produced by the 150 kHz Würth ferrite. It was trial and error because I have many and it turned out much better than I thought! I have more bass than before and better.

Matty, we honestly don't care about these anecdotal statements and they just don't belong on audio science forum, people keep mentioning it to you but you don't seem to care. I linked you to a proper testing of capacitors and you answer with some coloured/bolded text.

"I can not deny the improvement" is an absolutely worthless statement, how did you test? You swapped cap and listened without proper controls and think it's a fact?

I do not want open a long off-topic. If you want open a new thread or wait a while for them to arrive, install them and spend a few hours, after which I plan to open a specific thread where to comment on the new improvements? as well as the past ones.

Thanks for this. Bought Samsung Tab S4 and it works so much better than my 3 year old Samsung Tablet. Had dismissed it due to high cost before.
Same here. Nothing but praise. Much faster than the old one (tab S from 2014), which died in my case due to battery. I replaced the battery, it lived 2 more weeks and still died.
Headphone sound though I did not test. There is some gimmicky software processing at play - "Dolby Atmos on/off" and the "age adjustment" - mine is 30-60 years. It sounds "processed" to say the least - cleaner but you can feel that something is missing. Can we expect a measurement tour of Tab S4?

Ah, I guess I could measure it. :) It sounds better than my old tablet with headphones.

Maty, let's keep this thread focused on deals only. Explanations, etc. need to go in other threads.

^That's crazy cheap! I personally don't like them for listening though, they sound like some of the driest monitor headphones I've ever heard.

completely agree with you. not to mention they feel super cheap. I find them to be extremely overrated.
