The headphones arrived in about 5 days--surprisingly fast for shipping! While they have an open-ear design (which i initially worried might affect sound quality), i was pleasantly surprised by how great they sound after adjusting the settings via the accompanying app. The app lets you tweak eq levels, bass, and treble, and once customized, the audio is impressively rich and clear, even without fully sealing the ears. Considering their comfort, functionality, and the price point, these headphones offer excellent value for money. Highly recommend for anyone seeking a balance of convenience and quality!
