So why four stars? Two issues: they feel pretty fragile as they are made of plastic and they dont come with a case. The issue is related to the accessory posts attached to the top of the box. It only takes a minute or two. This adapter enables that connection. These could be wear-all-day walking around shoes. Already received compliments on these, not to mention they go with everything. 0, I was able to maintain a decent connection throughout my medium-sized apartment. Thanks Logitech! Bass is firm and punchy, but definitely not overwhelming. Time will tell if they have durability.
