1MORE SonoFlow vs Sennheiser ACCENTUM Plus (Black)
If you're torn between the 1MORE SonoFlow and Sennheiser ACCENTUM Plus (Black), the SonoFlow is your best bet for battery life with an astonishing 70 hours compared to Sennheiser's 50 hours. In real-world use, that means you can binge your favorite shows for days without reaching for a charger. The Sennheiser ACCENTUM Plus (Black) offers some advanced features like Adaptive Hybrid ANC and Sound Personalization, making it a compelling choice if sound quality customization is your priority. You'll appreciate the LDAC support on the SonoFlow for high-res audio, but it lacks the touch controls and EQ flexibility found in the ACCENTUM Plus (Black).
