I bought 4-5 of the cheapest speakers to see which ones would work best for my Bluetooth receiver projects on the Raspberry Pi. These were the best in terms of sound quality, they don't bother the ears after long hours of use, they don't have any buzzing like all the others, and they have satisfactory mids and bass, which were also missing from all the other speakers. Overall, they are the most value for money out of many that I have tried, especially considering their price. They are better than the Logitech ones that cost 50 euros and that I have had for 2-3 years. I wonder why many prefer this brand for PC audio, their sound is really bad.
