Hyperparathyroidism is where the parathyroid glands produce too much PTH. This causes blood calcium levels to rise (hypercalcaemia) and blood phosphorus levels to fall (hypophosphataemia).
Just two words: Quality and BlueTooth cannot be used in same sentence. The Sonos Play 3 is a very good sounding speaker for it's price range and is well made. You can't really compare it to a BT speaker as it really is much more. Your smartphone is mostly used as a remote for it rather than a source so your phone doesn't have to be on all the time you use it.
