Back in June 2016 I took a chance and bought the 1MORE Triple Driver in-Ear Earphones. While they seemed well-regarded, and well priced, their performance proved to be disappointing. For listening to music I eventually switched to a new pair of Etymotic ER3XR ear buds.
I continued to use the 1More headset for listening to podcasts, most typically when I was walking the dogs. The means that I used them quite routinely. So, it’s worth noting that, after two-and-a-half years, they’ve reached a point where they are physically degraded to the point of not being usable. In essence, I’ve discovered their lifespan.
The insulation on the wires from the point of the Y to the individual ear buds is now seriously brittle and falling away. This happened more on the right-hand side, which has the volume control. That’s because I often listen using just that side while walking the dogs. This helps me maintain greater situational awareness, which is important when walking two large dogs on leash.
At this point, the wire from the 3.5mm plug to the Y-point is not similarly degraded. I expect this is because it has a protective covering of woven cloth.
I cannot recall another headset that was so short-lived.
