Not for sound quality alone — HearAdvisor's lab measured the Select 300 higher on both speech-in-quiet (4.0 vs 3.1) and speech-in-noise (1.8 vs 0.8). The 700's extra cost buys Auracast support, a smaller design, and built-in Android hands-free calling, not better hearing performance.

Quick Verdict
AI summarizedSummarized with AI assistance from our human-researched product information, in-lab testing, objective sound measurements, and expert ratings.
The newer, pricier Select 700 adds Auracast and a smaller shell, but in HearAdvisor's lab it's the cheaper Select 300 that actually hears better in quiet and in noise.
Enhance Select 700
Choose the Jabra Enhance Select 700 if you want Jabra's most advanced noise processing, Auracast broadcast audio support, and the smallest Jabra RIC design, and you're comfortable paying roughly $100 more for it.
Enhance Select 300
Choose the Jabra Enhance Select 300 if you want the stronger lab performance in speech-in-quiet and speech-in-noise, a slightly wider fitting range that includes severe hearing loss, and a lower price.
What actually separates them
AI summarizedSpeech-in-noise lab performance
Lab measuredThe Select 300 scored 1.8/5 on HearAdvisor's speech-in-noise test versus 0.8/5 for the Select 700, and it also leads on speech-in-quiet (4.0/5 vs 3.1/5) — a real-world edge in restaurants and groups.
Price
PriceThe Select 300 runs about $100 less than the Select 700, which strengthens its case given it also tested better for speech in noise.
Connectivity extras on the 700
SpecThe Select 700 adds Bluetooth LE Audio and Auracast broadcast-audio support, plus Android hands-free calling built in (the 300 needs its Phone Clip+ accessory for that on Android) — both devices share iPhone hands-free calling and Android streaming.
Hearing loss range
SpecThe Select 300 is rated for mild, moderate, and severe hearing loss, while the Select 700 tops out at moderate, so buyers with more significant loss have only one option here.

Bottom Line
AI summarizedThe Verdict
This is an unusual case where the flagship doesn't win on core performance: the Select 300 beat the Select 700 on both speech-in-quiet (4.0 vs 3.1) and speech-in-noise (1.8 vs 0.8) in HearAdvisor's lab, while also costing about $100 less.
That makes the 300 the sounder pick for most buyers focused on everyday speech clarity and value.
Which is right for you?
The 700 earns its premium through connectivity and fit, not sound: it's smaller, adds Auracast broadcast-audio support and Bluetooth LE Audio, and includes Android hands-free calling without an accessory. Pick it if those specific features matter to you and you're willing to accept weaker noise performance and a moderate-loss ceiling in exchange.
Before you buy
AI summarizedTry the 300 first if noise is your priority
Its 1.8/5 speech-in-noise lab score beats the 700's 0.8/5, so test it in your noisiest regular environment during the trial window before paying more for the 700.
Check your hearing loss severity
If your audiogram shows severe loss, the Select 700 isn't rated for it — the Select 300 is the only one of the two that fits that range.
Decide if Auracast matters now
Only the Select 700 supports Auracast broadcast audio; skip paying for it if you don't expect to use Auracast-enabled venues soon.
