Some things don't change... Bose is still looked down upon, and their headphones are way overpriced; but for what it's worth the Soundlink mini II and the Soundlink III aren't bad. They don't have great quality but they are surprisingly not distorted and loud for their size, they have good battery life and good bass at about 80% volume. Any more volume and the bass rolls off, any less and there's more bass than anything else (isn't a bad thing for a bass head, just be warned) If you're playing music by the pool and want long battery life, good volume, Bluetooth and not wired to the wall all the time, the soundlinks are a great option. They're easy to use as well. I have the Soundlink III (got it as a gift) and I personally bought the Soundlink Mini II for on the go music sharing. It's nice to share new music with other people too, even when a $300 pair of sennheisers or ATH's or beyers will have a lot more sound quality.
Both of the speakers can be wired via aux cable too if sound quality on a Bluetooth speaker is really that big of a deal.
I don't understand the hate for Bluetooth speakers, they serve their purpose. Ease of use, portable, don't need to have an outlet and can share music with a medium sized room halfway full of people
