The SoundLink Mobile was replaced by the SoundLink Bluetooth Mobile Speaker II, sold from 2012 until 2014. It included a rechargeable battery that was rated at up to 8 hours of playback at moderate volume levels. The rear of the device includes a 3.5 mm auxiliary input. The appearance is very similar to its predecessor, with the biggest change being the folding arrangement of the front cover. Reviewers praised the updated version for its audio quality and high volume for a compact device, but criticized its high price and the lack of a speakerphone function.

The SoundLink Mini II replaced the SoundLink Mini in 2015. This featured the same sound quality and shape as the original SoundLink Mini with a few subtle changes. Firstly the controls on the top of the speaker changed from 6 to 5 individual buttons, removing the mute button and AUX button (The speaker changed to AUX automatically when it received a 3.5mm input) and added a multifunction button which could perform a variety of functions such as play, pause, and answer calls (due to the added speakerphone capability). The other major change to series 2 was the change from DC charging to USB charging, which provided a more convenient charging solution. The USB charging port also allowed the user to install software updates through btu.bose.com when available. The SoundLink Mini II was quietly discontinued in late 2018, favoring the newly released Revolve and Revolve+. However, due to high production numbers, it was still readily available as of late 2019. On 31 October 2019, Bose announced the SoundLink Mini II Special Edition. This featured the same design as the standard edition. However, it featured a better battery, which was capable of 12 hours of playtime and chargeable in 4 hours, as well as a USB-C port. The Special Edition is available in 2 colors, Triple Black and Luxe Silver. SoundLink Revolve
