Questions and answers

Which has better noise cancelling?

The Space One claims up to 98% noise reduction with ANC 2.0, which is a stronger claim than Sennheiser makes for the ACCENTUM's hybrid ANC. The ACCENTUM adds a transparency mode for hearing your surroundings.

Which lasts longer on a charge?

The ACCENTUM: up to 50 hours with ANC on, versus up to 40 hours for the Space One with ANC on. The Space One reaches 55 hours only with ANC off.

Is the ACCENTUM worth the extra money?

At $189.95 against a $55.00 recent low for the Space One, you pay for Sennheiser's tuning, the 5-band EQ and 10 more ANC hours. If noise cancelling and price lead your list, the Space One wins.

Which is better for calls?

The Space One lists a built-in mic with AI-enhanced call clarity and Bluetooth 5.3 multipoint. The ACCENTUM has two built-in microphones and multipoint but makes no AI call claim.

Which has better sound quality?

The ACCENTUM uses Sennheiser's in-house 37mm drivers and buyers describe a rich low end, though with less treble resolution than the Momentum 4. The Space One offers LDAC hi-res streaming, which the ACCENTUM lacks.
