This is the Astrotec GX100 earphones. Brand new, unopened, black, with no microphone, and a 3.5mm connector. I recently purchased these and have been carefully storing them on a shelf at home. The packaging has some minor dents. I do not have any pets, and I am a non-smoker. I am also listing this on other sites, so please forgive me if it sells out. Returns and cancellations are not accepted. For initial defects or missing items, please contact the manufacturer's support. I will ship via Yu-Packet Post (simple packaging) as quickly as possible. If the items are small, I can combine shipping, so please inquire in the comments. Please feel free to ask any other questions.
