The wrap-around-ear type of earphones are always more secure than ones that are not. They don't have a tendancy to fall out if you are excercising or eating. So they don't require constant checking to make sure one is going to be lost without being noticed.They have the rubber-plug type of fitting in the ear, which reduces external sounds from interfering. Different sizes are provided for differing ear sizes. They are comfortable for long-term use.The buttons on each earpiece are well located, where you would expect them to be, and they have a little positive 'click' when pressed. You would expect a single click on the left side to reduce volume, but it requires a long press to achieve that. Vice versa for the right side.Instructions are a bit sparse, but not altogether missing. For instance, I couldn't find any reference to 'pairing', but discovered that they seem to be willing to pair on opening the box. They are very willing to pair.The illuminated charge level of the box is handy, so you know when to recharge using the USBc wire provided. It is relatively quick to charge to 100%.Sound quality is good for me, and frequency levels are adjusted using the device equaliser. The microphone seems to work well enough for others to hear. Recommended.
