Short answer: the Bose Portable Smart Speaker for better sound quality, the Teufel Rockster Go 2 for the lower price. The Bose Portable Smart Speaker ranks #78 of 164 medium speakers, rated 3.4/5, at $399. The Teufel Rockster Go 2 ranks #91, rated 3.2/5, at $129.99, $269.01 cheaper.
The case for the Bose Portable Smart Speaker: Both Alexa and Google Assistant are built in, and RTINGS rates its microphones as excellent at hearing commands from far away or in a noisy room. The tradeoff: RTINGS found the out of the box tuning boomy and says it doesn’t get very loud; the app’s bass and treble sliders help, and SoundGuys recommended cutting bass by 10 to 20 steps to balance it.
The Teufel Rockster Go 2 is the lighter, tougher option. At 1.6 lbs (0.74 kg), the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. At 1.6 lbs (735 g) it weighs noticeably less than the Bose Portable Smart Speaker at 2.3 lbs (1.06 kg). It is rated IP67 against IPX4 for the Bose Portable Smart Speaker. It plays in stereo from a single unit, unlike the Bose Portable Smart Speaker. The catch: There is no companion app or 3.5 mm input.
Buy the Bose Portable Smart Speaker if sound quality matters more than the price. Buy the Teufel Rockster Go 2 if the price matters more than sound quality.

The Two Speakers In Full
Bose Portable Smart Speaker: $399.00 Bose eBay
Pros: Both Alexa and Google Assistant are built in, and RTINGS rates its microphones as excellent at hearing commands from far away or in a noisy room. It works as a Wi-Fi speaker at home (AirPlay 2, Chromecast built-in, Spotify Connect) and as a Bluetooth speaker away from Wi-Fi, weighs about 1 kg with a carry handle, and is IPX4 splash resistant. SoundGuys measured 13 hours 6 minutes of playback at 75 dB, beating Bose’s 12 hour claim, and found the bass impressive for its size, especially near a wall or corner. Its 360 degree design spreads sound evenly around a room.
Cons: RTINGS found the out of the box tuning boomy and says it doesn’t get very loud; the app’s bass and treble sliders help, and SoundGuys recommended cutting bass by 10 to 20 steps to balance it. Pushed to full volume, Tom’s Guide heard unbalanced sound and Pocket-lint found the bass struggling and turning incoherent. RTINGS measured only about 5 hours of battery in its own test. It is mono, has no aux input (the USB-C port only charges), uses Bluetooth 4.2, and the Bose Music app supports a limited list of streaming services. IPX4 covers splashes only, not submersion or dust.

Teufel Rockster Go 2: $129.99 Amazon eBay
Older model: the Teufel Rockster Go (ranked lower, rated 2.6/5).
Pros: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Independent listening found a balanced, clear midrange and tuneful bass at sensible levels.
Cons: There is no companion app or 3.5 mm input. Reviewers found it loses some definition at maximum volume, and the claimed battery figure is optimistic for loud outdoor playback.
