Im pretty underwhelmed with the armature, which doesnt actually hold the mic securely in any useful position. Awesome sandals , very coMfortable and great support I went down to the smallest silicone tip they offer, which I never do, but that allows the buds to sit a little deeper in my ears. This is great for young kids. As for the Bright & Tangy, it is not too strong yet very flavorful. Soft and cozy on the foot, but safety of a firm no slip sole is great. If both this and WS1100is is unamped, this sounds clearer since it was made to be used wireless so easier to drive. Other features worth mention is the ability to connect seamless to other devices, rather than just one. For wattage, look for 30w and be sure the full 30 watts is coming out of the USB-C jack. I ordered these sandals in 2 M US Little Kid and they fit very well - not too big, not too small.
