The Tennmak Pro I'd ordered went from "in a plane over the Pacific for a week" to "in my mailbox" with no intermediate updates and they are definitely well endowed in the lower end. The fit is quite nice though, which nicely confirms my suspicions about the general form factor based on how well my Sennheiser IE 40 Pro fit, and while I prefer a brighter signature I'm reasonably amenable to a wide range of signatures as long as they're reasonably cohesive and not too lopsided. Now to wait for my MMCX Bluetooth cable so I can figure which pair of IEMs will become my walking pair and which will be my backup.
