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.
The Good The Sonos Connect:Amp is an excellent all-in-one digital music system that offers superb sound quality. It gives you access to nearly any cloud music service (Pandora, Spotify, Amazon, Rhapsody, and so forth) using any iOS device or Android smartphone as a remote.ast in the list of connections is the subwoofer-out, which can be used to connect to a third-party subwoofer. Or you can opt to go with the wireless Sonos Sub instead. One feature I kept wishing for while using the Sonos was an IR port, usually in order to mute the system.
