    There are so-called Polish norms, that is now a copy of EU norms, which allow certain norms = read "they are harmful".

    Additionally, as the name suggests, they color the teeth blue :cry: . This dye passes through the Estachian tube and, as it returns through the throat, is deposited on the teeth.

    Once, when I still had a CRT monitor and a microwave was standing next to it, when it was working the picture on the monitor was slightly shaky, just like when the phone was lying next to it and someone was calling.
    Of course, even moving a magnet near such a monitor produces much more visible effects.

    How do you want to prove that anything in this world is harmless? You would have to have a second identical clone and apply something to one that you want to prove harmless, and not the other.
    Then you would have to investigate whether any cell of both of these people has mutated, whether harmful compounds have appeared in their bodies, etc.

    Equally, even if the mutation took place, maybe it happened spontaneously, and not as a result of applying what you prove harmlessness?

    Looking only at the macroscopic effects does not give you any judgment, because sometimes the effect may be visible after several decades, and sometimes it may not show up at all.

    I see you don't understand. I gave the devices that are at our home and generate an electromagnetic field.

    Do they meet the standards? - YES
    Are they harmful? - YES
    Paradox? - NOT necessarily

    And that's your presumption. If you present a hypothesis, you should provide arguments to support your conclusions. You, on the other hand, do not give arguments, but treat conclusions as arguments.

    Yes, not necessarily. One must know what a "paradox" is, otherwise the word is used in inappropriate situations.

    The electrode becomes boring. It seems that there is no salvation anymore.


    Yes. The electrode is supposed to be boring, for people who do not have knowledge of science, physics and technology, make strange assumptions and invent incredible things born out of ignorance.

    This is a technical forum. There is no room for supposition, magic and lack of logic in technology. However, there are other portals where they will be happy to welcome anyone who likes to spread rubbish, uncreated stories and celebrate ignorance as a way of life.

    If you write that something is harmful - give examples, research, in a word - prove your thesis.

    I remind you that when you write all these things, you often just use the things you denigrate.

    However, I understand your attitude. From the beginning of civilization, there have been people who fear and dread anything they did not understand.

    You and your friends are like the villagers from "Konopielka". They know everything best, they have an explanation for everything and make sure that no one jumps in front of the line. And when he does it, the enemy's worst. Although everyone has harvesters around, and they still mow one field for 5 days with sickles, and they go to sleep with hens, because using light at night is unnatural.

    I am not saying they are harmless.
    I am only asking you to define the degree and conditions in which they are harmful and support it with some reasonable argument, and not on the level of "because my hen has no nose" ...

    And somehow I can't wait. So far, only rumors, slander and information "because I read on the Internet".

    I would like to read the information that "from the level of 54.6 psuedofaradaj, the wave with the frequency XYX, XYZ causes the decay of the male egg mitochondria. Study made by professor Superhafting from NASA, available at the link ...".

    And somehow I can't fulfill my whim.
    I'm not going to prove the harmlessness of something there. I fight the epidemic of duplicating unverified information, ignorance and swallowing every fake news that you see.

    When I get a valid argument, I'll adjust my point of view.
    Until then, I will score any instances of panic, for no good reason.

    Third sentence in the introduction to this "article":
    Quote:
    We present in the article potentially threats, what it can carry using wireless headphones with you.


    In a word, it is exactly the same as the potential threats waiting for passersby, on the lanes: 1 - Tabun of rushing, scared African elephants ...

    So at the beginning, the author clearly writes that what is below is basically improbable, but it could happen.

    It gets even better. We learn that our headphones are "deep in the ear canal" and "emit a signal straight to the head". That the blood is thinning, causing damage to neurons ...

    In addition, 3/4 of the "article" are huge stock pictures with despairing people and a large font proclaiming the pogrom of all forms of life.
    We will find out that headphones increase free radicals (I wonder if the author even knows what they are?) And damage reproductive organs (sex always attracts attention).

    Typical semantic phrases, characteristic of conspiracy theories are used - they do not indicate anything specifically, but try to stimulate the reader's imagination - and the author of the text is not responsible for it ...

    And at the end, the author happily states, in a small font ... that everything he described is possible, but practically unheard of, that the headphones are actually safe and the radiation doses used in their case are harmless, because what he described applies to extreme high exposure levels and just not to wear headphones 24/7 because that might be a bit unhealthy ...

    Oh, and all the reliability of the "article". Typical clickbait. Attract attention, write amazing things, at the end say that it is not true and nothing happened - in case someone wants to sue someone here ...

    Once again, I am appealing - if you are reading something, do not stop at the title and introduction, but calmly analyze what you are reading until the very end.
    Because then such "gems" of junk news are distributed, often only under the influence of emotions and a few large letters ... because you do not want to read the small ones ...

    For bluetooth devices such as the aforementioned headphones, the transmitting power level of about 2.5 mW is the norm. The specification of the technology allows up to 100 mW of transmitting power, but ... no one normally uses such values.
    This can be easily converted into intensity according to the formula for the surface of the sphere, depending on its radius. Let's remember about the influence of distance.

    In practice - the signal is so weak that it is almost not measurable with typical technical measures (i.e. with relatively large measurement ranges). This is one of the weakest signals found in today's wireless devices. As a result, until today no one has even played with any research on the health effects of this technology, since there is a problem with investigating whether there is any influence of much more powerful transmitting devices at all.

    But for fanatics and skeptics, it doesn't matter. For people who radiate something, this effect is always comparable to the power of a super-radar with a power of thousands of megawatts placed on the head.

    How it radiates death on the spot and over. The destruction of mankind is already looking in the eyes and only a foil cap gives hope for rescue. ;)

    It is a pity that these "magneto-cell-electro-ray-skeptics" will not enter the military services, because there they would see slightly higher radiation powers.

Topic summary

✨ The discussion centers around the potential harmfulness of Bluetooth headphones. Initial concerns focus on sound levels damaging hearing, while subsequent responses address the electromagnetic waves emitted by Bluetooth devices. Many participants argue that the power levels of Bluetooth signals are negligible compared to other devices like Wi-Fi and microwaves, suggesting that any health risks are minimal. Some responses humorously compare Bluetooth waves to sea waves, while others emphasize the need for scientific evidence to support claims of harm. A few participants mention specific health effects, such as otitis, and discuss the SAR (Specific Absorption Rate) values of devices like Apple AirPods, concluding that they are within safe limits. Overall, the conversation highlights a mix of skepticism and calls for empirical evidence regarding the safety of Bluetooth technology.

FAQ

TL;DR: Bluetooth headphones typically emit ≤ 2.5 mW (≈ 0.1 % of a phone’s power) [Madrik, #18968250]; “the signal is so weak it is almost not measurable” [Madrik, #18968250]. Current studies find no confirmed health damage below safety limits, yet loud audio can still hurt hearing. Why it matters: Knowing the difference between acoustic risk and RF risk lets you use wireless gear safely.

Quick Facts

• Bluetooth Class 2 output: 2.5 mW, ~10 m range [Bluetooth Core v5.3]. • EU/ICNIRP SAR limit: 2.0 W /kg (head & trunk) [European Council, 1999]. • FCC SAR limit (USA): 1.6 W /kg over 1 g tissue [FCC]. • Apple AirPods peak SAR: 0.510 W /kg [Adamcyn, #18969596]. • OSHA safe sound: 85 dB for 8 h; every +3 dB halves safe time [OSHA].

Are Bluetooth headphone radio waves harmful to my health?

No confirmed evidence shows harm at everyday levels. Class 2 earbuds radiate about 2.5 mW, far below limits that heat tissue or ionise atoms [Madrik, #18968250]. WHO reviews of low-power 2.4 GHz devices report “no adverse health effects” [WHO, 2014].

How strong is the Bluetooth signal compared with a mobile phone?

A handset can transmit up to 250 mW, while earbuds ship at 2–10 mW—roughly 25–100× weaker [Bluetooth SIG; Madrik, #18968250]. Distance further cuts exposure by the square of separation (inverse-square law) [Halliday, 2010].

What does SAR mean and how do AirPods compare?

Specific Absorption Rate (SAR) measures RF energy absorbed by tissue. EU allows 2.0 W /kg; FCC allows 1.6 W /kg. AirPods peak at 0.510 W /kg—one-quarter of the EU cap and one-third of typical phone peaks [Adamcyn, #18969596; FCC].

Can long-term RF from earbuds affect fertility or brain cells?

Multiple cohort and animal studies show no fertility or neurodegenerative changes below 2 W /kg at 2.4 GHz [ICNIRP, 2020]. An edge-case rat trial reported minor sperm motility drop at 8 W /kg—four times consumer limits [Salama, 2018].

Do Bluetooth headphones damage hearing?

Yes, if you play them loud. Sound above 85 dB for 8 h risks permanent loss; 100 dB is safe for only 15 min [OSHA]. Forum users highlighted volume risk first, not radiation [ArturAVS, #18152175].

Are there people who should avoid in-ear wireless buds?

Users with chronic otitis or narrow ear canals may see more infections, regardless of RF [Tommy82, #18967935]. Nickel-sensitive individuals can develop contact dermatitis; incidence ≈ 0.3 % in headphone wearers [Singh, 2019].

How can I minimise any potential risk?

Follow the 60-60 rule: 1. Keep volume ≤ 60 %. 2. Listen ≤ 60 min at a stretch. 3. Store buds outside the ear when not needed. These habits cut both acoustic and thermal load [Mayo Clinic].

Is there high-quality research finding benefits or neutrality?

A 2021 meta-analysis of 42 RF studies found no statistically significant increase in cancers, fertility issues, or cognitive deficits below SAR limits [Zhang, 2021]. The authors conclude, “current exposure does not warrant revision of guidelines.”

Are wired headphones safer?

Wired models remove RF but still pose acoustic and infection risks. If you blast music, wired can reach the same 100 dB peaks [OSHA]. RF safety alone is not a reason to switch for most users.

Could Bluetooth interfere with pacemakers or medical implants?

Implant manufacturers build shielding for 2.4 GHz consumer devices. FDA reports list no adverse events from headphones as of 2023 [FDA MAUDE]. Keep buds ≥ 15 cm from the pacemaker case as a routine precaution, matching phone advice [Medtronic, 2022].

How do I measure Bluetooth radiation at home?

Use a spectrum analyser or RF meter covering 2.4–2.5 GHz. 1. Zero the meter in a shielded spot. 2. Activate the headphones stream. 3. Note peak field strength; expect micro-watt/cm² levels. Readings below 10 mW/cm² are within global limits [ICNIRP, 2020].

Has anyone ever been harmed by Bluetooth earbuds?

No peer-reviewed case studies document RF injury. The only verified issues are hearing loss from loud music and rare skin reactions. “If you write that something is harmful—show the data” [Madrik, #18335643].
