WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Sennheiser ACCENTUM True Wireless

What it brings

Rated battery is up to 8 hours per charge with ANC off (6 hours with ANC on) and up to 28 hours with the case, with 1 hour of playback from a 10-minute charge.
Manufacturer source
Each earbud weighs 5.5 g and the charging case 41 g, and Sennheiser lists LC3 alongside SBC, AAC and aptX, with Auracast offered by firmware update.
Manufacturer source

What to check

Calls use two microphones per earbud with beamforming for noise reduction, and the ACCENTUM True Wireless product pages do not state multipoint support.
Manufacturer source Manufacturer source
IP54 splash resistance applies to the earbuds only, not the charging case, and Sennheiser's codec list is SBC, AAC, aptX and LC3, with no aptX Adaptive listed.
Manufacturer source

Beyerdynamic AVENTHO 300

What it brings

Supported codecs are AAC, aptX Lossless, aptX Adaptive and LE Audio, so a phone or computer that supports one of these can use it instead of a basic connection.
Manufacturer source Manufacturer source
A rated 50 hours with ANC on, 10-minute quick charging for 5 hours and a supplied hard case and 3.5 mm cable suit long trips.
Manufacturer source Manufacturer source

What to check

SBC is not in beyerdynamic's codec list, and the sources do not say whether the USB-C port can carry audio.
Manufacturer source Manufacturer source
beyerdynamic does not state the test conditions (source, volume) behind the 50-hour battery figure, so real runtime may differ.
