These are not really the same size class, and that is the honest framing here. The Bose Lifestyle Ultra Speaker ranks #14 of 28 powered desktop speakers by sound quality at $299; the JBL Authentics 300 ranks #44 of 99 boombox speakers by sound quality at $499.95.
What the Bose Lifestyle Ultra Speaker does well: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. It keeps a wired aux input, which the JBL Authentics 300 lacks. The tradeoff: RTINGS lists sub-par directivity as its main weakness, and reviewers agree a single unit sounds narrow from side to side, so it works best as a stereo pair.
The JBL Authentics 300 is the battery-powered choice. Integrates both Amazon Alexa and Google Assistant simultaneously (rare for smart speakers). Its battery is rated for 8 hours, while the Bose Lifestyle Ultra Speaker needs an outlet. The catch: Narrow sounding, bass not as deep as others.
Buy the Bose Lifestyle Ultra Speaker at $299 for a powered desktop speaker, or the JBL Authentics 300 at $499.95 for a boombox speaker instead.

The Two Speakers In Full
Bose Lifestyle Ultra Speaker: $299.00 each Amazon $299.00 eBay
Same family: the Bose Lifestyle Ultra Subwoofer (subwoofer, rated 3.8/5).
Pros: Three drivers (a 3in woofer and 1in tweeter facing forward, plus a 1.5in driver firing upward) give it a noticeably taller sound than most compact home speakers. Stuff gave it the edge over the Sonos Era 100, and TechRadar called its tonal balance fairly neutral, with tight bass control and high detail. Alexa, including Alexa+, is built in, and RTINGS found its microphones picked up commands easily from across a noisy room. It streams over AirPlay 2, Google Cast, Spotify Connect and Bluetooth 5.3, keeps a 3.5mm aux input that the Sonos Era 100 lacks, and two units can be stereo paired or used as rear surrounds with the Lifestyle Ultra Soundbar.
Cons: RTINGS lists sub-par directivity as its main weakness, and reviewers agree a single unit sounds narrow from side to side, so it works best as a stereo pair. Deep bass is limited: Engadget found the low end restrained and preferred the Denon Home 200’s sound, Stuff noted it can’t separate sub-bass from the bassline and that DSP pulls bass back at maximum volume, and TechRadar heard a slight toothiness in the treble that needed EQ to calm. The EQ is only bass, mid and treble with no automatic room calibration. Bose warns the aux and Bluetooth inputs add lip sync delay for TV use, it has no battery or IP rating, and both SoundGuys and Engadget needed several restarts to get stereo pairing working.
