New stock has arrived! please read the detailed product description carefully. we kindly ask that you refrain from asking questions about information already included in the description. thank you for your understanding This product is also intended for export, but it's a sample that hasn't been finalized for any specific client. it hasn't been branded because the design wasn't ultimately approved, so it's leftover inventory without any labeling. The packaging and instructions are randomly matched by the foundry and are somewhat inaccurate. please refer to the introduction here. we will randomly send the packaging box and instructions, or only send headphones and charging cables, please know. The product was produced around march 2024 and is manufactured in china. In-ear design is better than wearing plaid, and the convenience of sports design . metal wire neck hanging. the headphones use 14.2mm units and high-resolution dynamic speakers. Bluetooth version: 5.3 Battery: we have newly replaced the 100 mah battery. currently, it can play music at 80% volume for 4-6 hours. Type-c charging port, only suitable for 5v1a charging. fast charging cannot be used. Estimated standby time: 24 hours. Headphone weight: 13 grams [excluding charging cable] The 13-gram weight is barely noticeable, playing just near your ear, making these incredibly comfortable and non-intrusive. however, this open-ear design reduces the bass impact, so you won't get that booming, deep low-end. you get what you pay for, i guess. the bass is there, but it's moderate, not heavy bass. the sound resolution is pretty good, so the music doesn't sound muddy. these are a solid choice for sports enthusiasts or everyday commuters. and the best part? our price is absolutely amazing! For specific usage instructions, please refer to the image and text above. volume control is only adjustable on your phone; the headphones themselves do not have this function. they are very simple. if you're having trouble pairing, please watch the video tutorial. The headphones are available in three colors: orange, black and milk tea.
