These are a great price, especially considering that Aftershokz costs a whole lot more, and the ones I bought broke after only a few months. They are not marked Left/Right, but actually, they only go in one way. I could havebought my true size in these. I didnt like having the confusion of the two names, and it should have spelled out why the title is one thing and the garment is another, but as I said, the item is the right thing. The included sticky tape and screw covers are the extra touch that set this product above others. This is my third pair in the last few years. Basically within the first two minutes I couldn?t wait to take them off. The fit is a tiny bit roomy, which I consider a plus. No bluetooth signal loss, no signs of wear at all (but I do look after my gadgets) and ANC is decent enough blocking Id say 80% of noise. The design is better.
