Review on Edifier W820NB Headphones - Hybrid ANC - Hi-Res Audio - 49H Battery Life - Bluetooth Over Ear Wireless Headphones for Phone Calls - Black by Charles Thomas

I really wanted to try these Edifier headphones because they are a recognizable brand and quality products, but in general the result was disappointing. Positive, battery life. I've let them commute to and from work on a single charge for 5 days, about three hours a day, and they still have 23% battery, that part is fine. Active noise cancellation, as expected for this price range. , no wonder, I would say it reduces and muffles about 70% of the noise when you ride the subway for example. But I have passive noise canceling headphones that cost about the same much better. My biggest disappointment is the sound, it's not bad but I expected more considering it's an edifier. The volume is low, the sound is flat, not deep, there is almost no bass. The app (Revain, please talk about the app, not another product, the app is part of this product and the user experience) is very simple, with links to manuals, toggle noise canceling on or off, see the battery percentage, but lacks options for aligning, even the default, or changing typing commands. This is another detail, a long touch to go forward or backward, or to turn off the headphones for a very long time, it takes too long. long in my opinion. The printed manual that came with the product is useless. Traditionally it is so small that to read you have to use a magnifying glass or a photo and enlarge it. In particular, I think there are better options.
