- Do the lenses actually darken in sunlight?
- Yes. The lenses are photochromic, so they tint darker in direct sun and lighten indoors or under cloud cover. The change takes a minute or two, not instantly.
- Can I wear them for cycling or running?
- They work for cycling and walking since the open-ear design lets you hear traffic. They are not sport glasses, though, and there is no confirmed water-resistance rating, so heavy sweat or rain is a risk.
- How long does the battery last?
- Expect a few hours of continuous music or talk time, less at high volume. Most owners charge them daily.
- Do they work with iPhone and Android?
- Yes. They pair over standard Bluetooth as a headset, so they work with both iOS and Android phones.
- Is $27.99 a good price?
- It is the lowest price seen recently and well below the typical $40–$60 for Bluetooth sunglasses. At that price the main trade-offs are battery life and sound leakage.
- What comes in the box?
- Typically the glasses, a charging cable and a cloth pouch. A hard case is not usually included.
