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.
Sonos operates on WiFi, which means the Sonos system covers the entire range of your WiFi network. As long as your WiFi reaches all the rooms where you want to put a Sonos wireless speaker, you won't have any issues with range. Music keeps playing â without skips, delays or drops â regardless of where your phone is.
