Langsdom JM21 - Review | ThePhonograph.net
www.thephonograph.net
You can see many of their products here. The Langsdom JM21 feature flat cables and a fairly large 10 mm dynamic driver inside housings that are made of plastic and are very light weighted, the cables besides being flat are substantially rubberized and do a very good job against tangling issues. Because of their low selling price you will probably doubt about the Langsdom JM21’s sound quality but we have reviewed other of the most sold earphones on Aliexpress like the Inpher Fuqing B-2 (check the review: Inpher Fuqing B-2 Review) that had a similar price tag and resulted to be one of the Best Bang for the Buck Earphones, so we will see during the Langsdom JM21 soundtests how they perform. The 10 mm dynamic driver of the Langsdom JM21 provides a highly energetic bass response with very punchy mid-bass and crazy deep sub-bass right out-of-the-box. Mid-bass is so strong that, unfortunately, can sound boomy too. Applying an EQ, bass gets insanely punchy and deep but also very boomy. Mids of the Langsdom JM21 are very warm and exhibit a lot of mid-bass bleed. Lower vocals still manage to fight back in the boomy sound environment but due to the strong mid-bass bleed the overall sound is congested. Higher mids are crisp and are usually not harsh.

It is clear that the price is inflated and they are cheaper in China, but I still believe that shops should sell the high quality goods. Why do people manufacture this? Returning to the topic, I was overcome with curiosity and solved to buy Langsdom Mijiaer JM21 to test it personally. Now let's go to the most important thing — the sound quality. Initially, I solved to compare it with my headphones from Xiaomi, which I use constantly. But I specifically decided to listen to Langsdom first, so as not to distort the perception. I played several tracks of different styles: rock, pop, trance.
