I bought these for max deadlifts and other exercises such as pull ups and heavy rows once my grip is spent. Read that cakes can be made in these. Theres some base but it doesnt affect voice clarity whichs nice. I wear them daily (AZ). so happy so far will update if that changes But it did make all the different in allowing my foot to fit! A perfectly working replacement for a damaged 2. For a large headphone they are very lightweight and can be worn for ages with no problems at all. Subjectivity at its finest! The middle is good for my front wheel and any storage.
