(Part 1) I’m giving this sandal 2 stars for only one reason: the majority of the straps are not adjustable, the one strap that does adjusts is minimal at best; it “tightens” or “loosens” . Character development is top of any shows out there. While pleased with my purchase I don’t think the price matches the performance but maybe that’s a testament to the quality of the Plantronic and not a fault of the Astro’s! When I added a belt, all the extra material flopped over the belt and it just looked like a mess. They were not work over winter and this summer I have continued to wear them in, as advised by many a blog, and have been patient. ive emailed the company and they said the straps are out of stock but I found them on Amazon and you would think they would offer to provide more but they didnt. If you stray just a little bit to any direction, it doesnt recognize it as a center press, but a directional press, thus making it not turn on or off. Headset is comfortable and the connection is reliable. Im no audiophile but the sound quality is excellent to me. This was a birthday gift for my wife.
