    Thanks! That cleared things up. The 8:1 is more of a safe number to go by. The output is 47 in my case, so I think a headphone with 250 or more should be fine.

    But why they say you need a headphone with at least 8 times the impedance of the source's output?

    According to those links, the headphone being 8~10 higher shouldn't be the ideal? So for the 47 headphone output of my multifx I would need at least a 400 ohms headphone? This seems a lot. Is...

    The source (amp output) impedance should ideally be lower than the headphone impedance (the rule of thumb I see thrown around is generally a 1:8 or 1:10 ratio). If they are too close or the headphone is higher than the amp, it can lead to some coloration of the sound.

    According to those links, the headphone being 8~10 higher shouldn't be the ideal?

    So for the 47 headphone output of my multifx I would need at least a 400 ohms headphone? This seems a lot. Is there any budget options for this?

    Gotcha. But does this happen with headphone outputs? Are there headphone outputs with this much power? Anyway, the AKG K240 should be a safe choice in my case? According to that link it can go...

    However - there is an exception. Sort of. If equipment is impedance matched but power-mismatched (ie, headphones can accept 5w but output from an amp is 200w), all that 200w is going to flow to headphones only able to handle 5w and blow them up.

    Gotcha. But does this happen with headphone outputs? Are there headphone outputs with this much power?

    Anyway, the AKG K240 should be a safe choice in my case? According to that link it can go from 55 to 200 and the average is 87.

    I have a guitar multi effects that has a headphone out with 47Ω

    I want a budget somewhat neutral headphone to use with it and I am getting confused with the answers I found so far.

    The AKG K240 mk2 (55Ω) seems to be a popular choice with people who own another multi effects (HX Stomp) with a different impedance (I think it's 12Ω).

    This headphone is within my budget, but it seems too close to the 47 output of my multifx.

    Will I have a problem with this?

    I read somewhere that the headphone impedance should be much bigger than the output impedance, but another text I read somewhere explained that they should match closely.

    I'm really confused about this.

    About not supporting Amazon, there is nothing, absolutely nothing me, you, anyone as a person can do. Individuals can't do shit against this. The same way that we can't avoid climate change by taking shorter showers, recycling and everyone planting a tree.

    I am a communist and I buy communist material from Amazon lol

    The only way to lower Bezos influence is to expropriate everything from him. And the only way to save the planet is to stop living for profit.

    And we can only do that if we overcome capitalism, because as soon as Bezos is gone, there will be another one the next day.

    Here in Brazil Amazon is strong, but still mostly books and some other things. For almost everything, MercadoLivre is stronger. In some places they can deliver in the same day.

    Shein is for clothes, specially for women.

    I prefer shopping online instead of going to a store simply because I don't want salesperson chasing me pushing products and there are much more options online anyway.

    Thanks! I'm not set on HRT. I want to avoid if possible because I heard it can affect sperm count and I want a child in the near future, but going from 370 to 250 in a year doing everything "right" I don't think diet and exercises (my numbers are going up on a weekly basis) are really the problem, but it is worth a try messing with ratios.

    I plan to investigate all I can before jumping on HRT.

    The only thing I don't like is the Murica super strong vibe it gives in the flashbacks. It is the usual USA propaganda, but it always makes me roll me eyes.

    Yes, I take fish oil daily and eat fish at least once a week.

    My workout is not that light, but since I have a home gym it is limited, but I have good numbers and train with intensity instead of volume.

    Monday is:

    • Overhead Press
    • Inverted Row
    • Rings Pushup
    • Weighted Pull Up
    • Lying Tríceps Extension
    • Curl
    • AB Wheel

    Tuesday:

    • Squat
    • Leg Curl
    • Kettlebell Swing*

    Thursday

    • Weighted Dips
    • Weighted Chin Up
    • DB Press
    • DB Curl
    • Rope Pushdown
    • Cable Crunch

    Friday

    • Squat
    • Romanian Deadlift
    • DB Sumo Squat
    • Kettlebell Swing*
    • kettlebell swings are done as cardio (10 minutes EMOM)

    I do weighted chin ups with 23kg hanging, squat 1rm is 120kg and weighted dips with 30kg.

    Diet is real food. I don't eat garbage on weekdays, only weekend. Plenty of rice and beans (I'm Brazilian), chicken, red meat, fish, broccoli, greens, carrot, etc. Protein shake with peanut butter, banana and apple every day. Milk and oats and three eggs in the morning.

    I eat at maintenance (2400 kcal). Height is 178cm and weight 74kg.

    I was slow bulking with 2600 kcal gaining 1kg per month, but now reduced to 2400 to maintain for a while.

    Thanks. I found an urologist that works with these issues and have an appointment next week.

    Apart from losing my older brother last year, my life is stress free mostly. I work only 10 to 20hrs / week. Maybe my genetics are against me on this one. Thankfully I have full thick long black hair still, so there's that good part of my genetics going on. 🤷🏾‍♂️
