All the same, it is a procedure that is not without risk.
https://www.healthline.com/health/ear-irrigation#risksI would not suggest doing it yourself, and would suggest seeing a GP if you need it done with a syringe. Personally, I have never had problems with low concentration peroxide, as long as you do a nice distilled water flush afterward, and dont leave water in. Your mileage may vary.
I would be very concerned that a typical human type person with a syringe (especially the plunger kind) would be able to damage their ear drum on accident from having too much pressure on the jet, and poor control of the syringe. Eardrums are very sensitive to pressure, and are delicate things. People, by and large, are not very smart ad if they feel their ear is "really stopped up" may be tempted to "really squirt it in", with bad consequences. Just because it is what the GP does does not mean it is perfectly safe.
Here's a nice scholarly article that tracked the incidence rate of complication from irrigation in a clinical setting:
http://www.bmj.com/content/301/6763/1251They give odds of adverse outcome from outpatient irrigation at 1/1000, and I would expect the odds of it happening in a less controlled environment (like your home) by an unskilled practitioner (like your average human type person) to be much higher than that.
If you dont want to take the word of some guy on the internet, then how about a clinical researcher?
Most general practitioners syringe wax from the canal with a traditional syringe, which can develop pressures of up to 16kPa (110 psi). A few use other water irrigation methods, including dental irrigation systems such as the Water Pik.'7 It is important that the person performing the syringing is fully instructed in the technique. Five general practitioners did not know if their nurses had been instructed in the method of ear syringing.
Further, some doctors actually do recommend the peroxide route.

Other ear-cleaning options you should eliminate include ear candling and rinsing with a syringe and water. Kim says that ear candling—which involves putting a hollowed-out candle into your ear, lighting it, and hoping that the suction caused by the heat takes out the earwax—is likely to cause more harm than good. "The heat could potentially burn your ear drum, and it's possible that the candle wax could get stuck in your ear and cause even more of a problem," she says. Trying to flush out your ears with water sounds safe in theory, but Suurna says that the water could get stuck behind the wax or cause the wax to swell due to the moisture.
Your New Earwax Removal Go-Tos
With all of that out of the way, it's good to know that there is actually something you can do to help clear out earwax. Kim says to put a drop or two of hydrogen peroxide in your ear about 10 minutes before jumping in the shower. The peroxide will liquefy the goo and help it rinse out as you go through your normal shower routine. Doing this once a month should help keep things open.
I can probably find others.
Yup, found another.

5. Rinsing With a Syringe
Rinsing with a syringe can be safe, but if you neglect to dry your ear when you’re done you could end up with swimmer’s ear. Generally, there’s no need to rinse your ears with a syringe.
...
An ear, nose and throat (ENT) doctor, or otolaryngologist, can remove earwax using a special suction, miniature instruments and a microscope. If your eardrum is perforated, manual removal by a physician is recommended, however in most other cases you can clear earwax blockages at home.
The simplest way to do this is to first soften the wax by placing a few drops of olive oil, coconut oil or water in your ear. Then, pour a capful of 3 percent hydrogen peroxide in each ear to flush the wax out. It’s worth noting that using plain sterile water, or a sterile saline solution, to soften earwax works just as well as oil or over-the-counter eardrops.
As an aside, the hydrogen peroxide trick (pouring a capful of 3 percent hydrogen peroxide in your ears) also works remarkably well at resolving respiratory infections, like colds and flu. You will hear some bubbling, which is completely normal, and possibly feel a slight stinging sensation. Wait until the bubbling and stinging subside (usually 5 to 10 minutes) then drain onto a tissue and repeat with the other ear.
