Do the ear hooks actually keep them in while running?

The rigid loop sits over the ear and is the main reason people pick this style. It holds better than plain tips for most wearers, but fit still depends on your ear shape, and glasses can make the hook feel tight.

Can I connect two devices at once?

No. These have no multipoint, so you pair with one device at a time and switch manually. If you move between a phone and a laptop often, that gets tedious.

Is there noise cancellation?

No. There is no active noise cancellation and no transparency mode. The in-ear seal blocks some background sound, but you will still hear traffic and gym noise.

What Bluetooth version do they use?

Bluetooth 5.4, which is current and gives a stable link with modern phones. Range and latency are typical for budget earbuds, so expect slight lag on video in some apps.

Are they good enough for calls?

They work for short calls, but the microphones are basic and pick up surrounding noise. For meetings or windy outdoor calls, a headset with a boom mic is a safer choice.

What comes in the box?

Typically the earbuds, a charging cable and basic documentation. Check the listing for the exact contents and whether a charging case is included, since bundles vary.
