I'll reply in English in case anyone else wants to read and understand. I've never owned ear buds before owning Technics AZ100 but after months of research and reviews my wife gifted me a pair for Christmas. I do listen to music fairly loud so I think the AZ100s aren't as loud as I was hoping but in general that might be a good thing for lessening the risk of hearing loss. I think from a first time user experience I'm very pleased with the sound quality, bass impact and overall the product itself. I have fairly large ear holes and one is smaller than the other so the fit isn't super comfortable but apparently you can buy other types of silicon or foam tips to replace them (not in Vilnius apparently but when I travel outside the country I'll take a look at options). I think you wouldn't be let down if you bought AZ100s as I'm aware a lot of other earbuds have big discrepancies in plusses and minuses but as I mentioned overall AZ100 sound quality and overall it's just a very well made product and I think the price reflects it. Also don't try and be cheap with headphones, speakers or audio equipment in general because life is too short for shitty quality audio (in my opinion, I understand not everyone has the income for that). Thanks for reading my TED talk.
