Harman Onyx 3 vs Onyx 4: Which Bluetooth Speaker Wins in 2024?
Harman Onyx 4 is the 2024 refresh of the Harman Onyx 3 Bluetooth speaker, packing a bigger 50 W amp, USB-C charging, and refined DSP that widens the soundstage while trimming 200 g of weight.
Shoppers mix them up because both share the same flying-saucer shape and fabric grill; the only giveaway is the darker metallic finish and USB-C port on the 4. Retailers often list both as “Onyx Studio,” adding to the confusion.
Key Differences
Onyx 4 upgrades the driver array for deeper bass, swaps micro-USB for USB-C, and adds Bluetooth 5.3 with multipoint pairing. Battery life jumps from 5 to 8 hours, and the companion app now offers EQ presets unavailable on the 3.
Which One Should You Choose?
Need future-proof ports and richer lows? Grab the 4 at today’s $199 street price. If you only stream podcasts and find the 3 for under $120, it still slaps—and your micro-USB cables stay relevant.
Does Onyx 4 work with older micro-USB chargers?
No, it has USB-C only; use the included cable or any 30 W PD adapter.
Can I pair two Onyx 3 units with one Onyx 4?
No, Harman’s Connect+ feature is model-specific; mixing generations breaks stereo pairing.
