A:AnswerHi Barry - here are some key differences. The 2nd Gen has an Equalizer in the app, whereas the 1st Gen does not. The 2nd Gen also has a Shortcut button, which can be customized via the app for accessing e.g. Speaker Link, your voice assistant or Spotify Tap. The 1st Gen doesn't have a Shortcut button.
A:AnswerYou do not need a case. We bought as a gift and bought the cases because the person camps a lot with Boy Scouts and figured it would add extra protection
A:AnswerWe regret that we don't understand the question. Please contact BestBuy or Bose customer support with your question, so that you can find further assistance.
A:AnswerHello Hack, if you have two SoundLink Flex speaker you can use them separately and play different content on each speaker or alternatively group the two speaker to play the same music.
A:AnswerThe SoundLink Flex (2nd Gen) speaker wasn't specifically designed for this purpose. Officially, we can recommend using "Speaker Link" to connect to another SoundLink Flex (2nd Gen), or to a SoundLink Max speaker. Make sure you have the shortcut button set up for Speaker Link.
A:AnswerPlease note that Bose does not give out decibel-related information about this speaker. We would recommend that you give the speaker a try, and see if you're satisfied with its performance. Our support team is happy to help in case of any questions or issues.
