Yes, it hurts, maybe using few time, interleaved with another over-the-ear phones can be good idea.

Thanks for the tips! I will consider a large phone.

Fidelio is very expensive for me.

Considering the In-Ear phones, I would get the KZ ATE and KZ ED9, both cheap and good quality, each one has it's advantages, see reviews on audiobudget site.

Considering a large studio phone, this is the one that I can afford, only 35 usd shipped, with good customers reviews:

I liked the HD668b reviews, but here it is almost twice the price compared to the SHP20, which has a similar construction.

shp80 is more expensive and hard to find, and I do not like the velvet around the ears, can be confortable but will get dirty soon...

I think I will decide between Arcano SHP20 and Superlux HD668b. Time to read and see some reviews and take a little time to decide.

Thanks a lot for all the tips.

The most intriguing, surreal and fun part of reading earphones reviews is trying to understand a sound by reading words. I needed to do some google research and read about the words often used to describe an audio: warm, dark, bright, harsh, piercing, and so on... (type things like this on google: what is a warm audio?)

There are mixed reviews, some says astonishing, other says so so, other says bad for the same phones. Interesting thing is: sometimes a review say bad things and deliver a good grade/record number classification. Sometimes a review say good things and deliver a bad grade/record number classification.

Sonarworks has an interesting DAW plugin. They did analysis in many earphones and developed a "turn into flat"/"turn into calibrated" equalization plugin. In their website, listening the same sound with/without the calibration for a given earphone can show how much the given earphone differs from "ideal" earphones. They say there are not perfect earphones, even the most expensive will not be perfect calibrated due to the materials limits.

About the large over-the-ear phones, I was considering the Superlux, but people says it has a small amount of harsh in trebles. Sonar calibration shows a very downgrade in trebles to calibrate the Superlux earphones, so I concluded that this is true. Taking this into account I decided to give a try in the Arcano SHP20 phones because it is cheaper and has good customers reviews, and the more expensive Superlux are not perfect to deserve the extra money. I decided to get a large earphone to avoid hurting the ears with in-ear phones when using long time.

About the in-ear phones, here in my country the KZ are very popular and easy to find for reasonable prices, and the reviews are ok, so I decided to go for it. I need a small portable earphones for in the field audio monitoring, and an unobtrusive/discreet solution. So after reading a lot I perceived the KZ ATE to be the best choice. They do not fall from the ear, have good ambient sound isolation, and people says it sounds good.

I am very curious about the KZ ED9, because it has a more flat/balanced frequence response curve, two options for bass changing the nozzle, and reviews says it sounds astonishing. (some says the trebles are a little harsh but perfect at same time with great classification numbers). But two things are not adequate for audio recording monitoring: they can get loose from the ear if you move yourself, and they have open backs which can spread a small amount of sound to the ambient. If someday I can have the extra money to buy, I will give it a try mainly for enjoy music and maybe for using with a DAW software interleaving with the Arcano.

I found a very interesting website which provides tone audios for testing earphones. One of the most useful audios starts at 20HZ, start changing and goes up to 20KHZ, so you can perceive if your earphones can respond adequate to all frequencies.

I got a KZ ED9 to use with a Xduoo X3 DAP. It's very clear with adequate bass.

I just compared the KZ ED9 with the SONY-MDR-NW750N hi-res earbuds on a SONY DAP. The KZ ED9 actually sounds way better than the Sony Hi-res earbuds which cost 10 times more.. better bass presence than the Sony.

( right, earbuds are OK for portable music or radio only! Earbuds always fall out, but a little gaffers tape will hold them in :) .. )

@apefos

Unless you want to work in music studio requiring total silence closed headphones have inferior sound, it is just due to physics of too small space and too much reflections.

Btw instead of hours spent on selection of cheap headphones you can find any payable work and try to save on best ones.

Final decisions:

Large Phone: for long time working in audio mixing and video editing: Arcano SHP300. Main reasons: 1-price: 56 usd. 2-good build construction 3-excellent customers reviews, most 5/5 and some 4/5. 4-replaceable cable 5-one review said that phones around 20/30 usd more expensive are not better in sound and construction to deserve the extra money. 6-some says it has a good flat response ideal for monitoring/mixing and shows all audio details 7-closed to avoid sound out. 8-large and confortable foams surround all the ear. 9-Best selling phone here in my country, seems to be the best buy. 10-similar to ISK HP980, ISK HD9999 and AKG K271.

The SHP300 headphones arrived.

I heard some different musics on it.

The sound is ok, clear, without confusion in frequencies, without harsh or sibilance in mids and trebles. I can identify all instruments and good voice.

The sound is good quality, very easy to equalize, with just minor adjustments in frequencies it gets ok. It is almost flat from factory with some more bass and some more mid-high.

There is just one thing that I don't know if can be bad at all... The bass frequencies are velvet, and if I lower them to try to remove the velvet feeling the bass intensity gets lower, but the velvet sensation does not fade away. So I need to get accustomed to this characteristic.

Best average equalizer settings (sound card software):
60=-9, 170=-7, 310=-5, 600=-3, 1k=-1, 3k=0, 6k=-3, 12k=-3, 14k=0, 16k=0

I did more music listening and I perceived that there are musics with lots of bass, and other musics with a better mixing where bass sounds pretty calibrated, so I think the shp300 headphones can be used for audio mixing and no problem at all.

The different artists and studios uses diferent equalization in their musics, so the shp300 is ok for perceiving the best equalization.

I am starting to believe there is nothing wrong with the headphones, I am starting to believe that some music equalizations are wrong.
