I consider the headphones very good with a good cable. They also have spare plastic parts for the ears, as well as a controller on the cable. With the button, you can accept or reject calls or play music. They are not headphones for high-fidelity sound reproduction, but rather small-sized hands-free devices. Considering their small size, I find them very powerful. I use them with a helmet on my motorcycle and I can hear and be heard very clearly, as well as receive instructions from the GPS. I never have them at maximum volume during conversations or GPS navigation. They don't bother me at all, even when wearing them with any of the three helmets I have, for many hours. I think they are the perfect choice for a helmet. The only thing left is to see their durability over time.
Edit 1-6-2023. Well, the headphones last about 4-6 months. After that, they stop working. However, either the company or the store replace them under warranty. I have purchased another pair and have replaced them a total of four times.
