Managed to get them during second discount tier, so until 250 unites ordered. Quick delivery form Checia to Poland, indeed. Box hasn't been even wrapped in boubles, but hasn't suffered during transport, fortunately. Build quality is pretty descent. No cracking out of the box. Most of past are made with some kind of plastic, but the "hinges" and "boons" are made with metal. Ear pads are made with some kind of memory foam and work well with glasses. However, do not expect great sound quality. Even though, these headphones are dual driver, the music sounds somehow muffled. There is no separation between highs and lows, and you don't really hear mids. ANC works OK, transparency is not good. Blitzwolf logotype at the top of the headband should be more supple 🙄
The sound quality is average, the middle is failed, sound like that deaf, the source is iPhone 14 pro, cheaper headphones for example AirAux AA-ER3 sound much better, and the highs are, and the middle is in place, and the bass is resilient.
