Coming from a wired headset user, I enjoyed, non-existent audio delay and how easy it is to use it. Just plug it in and it works. I've tried wireless headsets in the past but either there is a delay in the audio, or the connectivity is finicky to say the least.
When I tried out these earbuds, I exceeded my expectation. I can connect 2 devices at once without having to be a software engineer for it to work, there's no delay, I can move around without having to get tangled in wires. It is honestly a solid pair of earbuds.
Now to the cons. Though I can connect to 2 devices at once, I can only hear audio from one of the devices at a time. If I'm listening to music on my laptop and I get a call on my phone, it would completely turn off the audio from my laptop completely instead of reducing it. I would prefer if it had an option to customize that. Nothing special with the audio but it's crips and clear for its price.
