" "Simple to use, connected right out of the box. The earbuds had very good sound quality when I used them to listen to music. Changed out the ear tips to the smaller size which helped them fit better for my ears. Audio during my phone calls was good, had them connected to my laptop during Zoom calls without issues. Managed to get around 5.5 hours of playtime on them before hearing the low battery alert. Overall very pleased with the purchase so far.""
""These earbuds right out of the box is fantastic!! For the first time in a long time i didn't have to change my ear tips. The sound quality is also great 👍 and they get plenty loud as well. They are also very comfortable and I didn't experience any ear fatigue. I had my girlfriend help me test out the call quality and I had the TV on. Not very loud but good enough and it didn't pick up any back ground noise.""
