THE DIFFERENCES, MADE VISIBLE

Visual facts

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.

FEATURES SIDE BY SIDE6 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC

01 / 06

Microphone

A built-in microphone matters for calls and voice chat. An audio-only headphone connection does not supply a microphone channel.

Beats Powerbeats FitYes

Manufacturer specification · Three microphones per earbud (six in total) with beam-forming for calls; an internal processor reduces external noise such as wind.

Source 1

Beyerdynamic DT 900 PRO XNo

Manufacturer specification · Supplied cables end in a stereo headphone jack; no microphone is listed.

Source 1 Source 2

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 EACH CHOICE ASKS OF YOU

What it brings and what to check

Beats Powerbeats Fit

What it brings

A flexible one-size wing tip tucks under the ridge of the upper ear to hold each earbud in place, and at 5.78 g per bud and 49.75 g for the case they are lighter than Powerbeats Pro 2 (8.7 g and 69.0 g).
Manufacturer source Manufacturer source
Both the earbuds and the charging case are rated IPX4 for sweat and water, and the page lists ANC, Transparency, Adaptive EQ and personalised spatial audio.
Manufacturer source

What to check

Shorter rated battery than Powerbeats Pro 2: 6 hours per charge with ANC on and 24 hours with the case, versus 8 and 36 hours, and no wireless charging is listed for the case.
Manufacturer source Manufacturer source
Uses the Apple H1 chip where Powerbeats Pro 2 uses H2, has a single multi-function button per earbud with no volume rockers listed (the buttons can be set to adjust volume), and ships without a charging cable. Beats gives no Bluetooth version.
Manufacturer source Manufacturer source

Beyerdynamic DT 900 PRO X

What it brings

A 48-ohm nominal impedance and a rated 100 dB SPL at 1 mW mean it is specified for use with laptops, tablets and phones as well as studio interfaces.
Manufacturer source Manufacturer source
The single-sided cable detaches at a mini-XLR connector and can be replaced by cables of different lengths and connection options; the ear pads and headband pad are also replaceable.
Manufacturer source Manufacturer source

What to check

It is an open-back design (beyerdynamic's operating principle: open) with no active noise cancellation, and neither the product page nor the spec sheet gives an ambient-noise attenuation rating.
Manufacturer source Manufacturer source
There is no microphone or inline remote; the supplied cables are audio-only stereo leads.
