How to read this comparison

Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

SELECTED TOPIC

Open-back design

Open-back earcups are not sealed. Start here if your listening space is quiet; this construction is not a sound-quality rating.

Choose your must-haves

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

What it brings and what to check

Beats Powerbeats Pro 2

What it brings

Nickel-titanium ear hooks, an IPX4 sweat and water rating and physical volume rockers on each earbud suit running and gym use, and the optional heart-rate sensors feed workout data to compatible apps.
Manufacturer source
Beats rates 8 hours per charge with ANC and Transparency mode on and 36 hours with the case, and the case charges over USB-C or Qi-compatible wireless chargers.
Manufacturer source Manufacturer source

What to check

At 8.7 g per earbud and 69.0 g for the case, they are heavier than Beats' Studio Buds + (5.0 g per bud, 49.0 g case).
Manufacturer source Manufacturer source
Beats does not publish a Bluetooth version or codec list, and no charging cable or power adapter comes in the box.
Manufacturer source Manufacturer source

Sennheiser HD 600

What it brings

The detachable 3 m cable and velour ear pads can be replaced, and optional 4.4 mm and XLR-4 balanced cables are available for balanced amplifiers.
Manufacturer source Manufacturer source

What to check

At 300 ohms with a rated 97 dB SPL at 1 kHz / 1 V rms, check that your amplifier or audio source can drive the headphones properly.
Manufacturer source Manufacturer source
The open-back design leaks sound and lets outside noise in. Sennheiser's pages disagree on whether the cable ends in a 3.5 mm or 6.35 mm plug, so check the listing.
