abxtest.com - free online service for blind ABX audio testing. Find out at what bitrate you actually hear the difference between compressed MP3 and lossless WAV on your headphones, speakers, and gear.
"I've got perfect ears - prove it. Or shut up about FLAC." 😏
You listen to three versions of the same track: A (compressed MP3), B (lossless WAV), and X (either A or B). Guess blind - no hints, no forum magic. The result shows your hearing threshold: the highest bitrate where you can still tell MP3 from lossless.
- Figure out if you actually hear the difference between Spotify Free (128 kbps), Premium (320 kbps), and lossless
- Check if your audiophile obsession is justified on your real setup
- Compare yourself in the rankings - headphones, sound cards, devices, countries
- Fast, no install - right in the browser, phone or PC, whatever you've got
The test walks you through 96 → 128 → 256 → 320 kbps vs reference WAV. All versions cut from the same master, loudness matched to EBU R128 - so you're comparing compression quality, not volume. Fair fight. 🥊
Classic A / B / X setup. Two correct answers in a row - next bitrate. Two wrong - test's over, you learn your ceiling. Not sure? Skip the track, no penalty.
Drop in, pick your gear, take the test, get your result. 20 random tracks, shareable link, challenge a friend.
Email + nickname. Your page at abxtest.com/your_nick, full test history, genre pick, 200+ tracks.
- Pair tests - same track set, two results side by side. Who hears better, you or your bro? 👀
- Acoustic test - same tracks, different setup. Headphones vs speakers, built-in DAC vs external
- Hearing profile - by genre (rock, jazz, electronic, hip-hop, classical, pop) and by format
- Rankings - show up on the leaderboard

Who hears what, on what:
- devices (MacBook, PC, phones)
- headphones & headsets
- sound cards & DACs
- people - worldwide and by country
English, Русский, Deutsch, Español, Français, Português, 中文, 日本語, 한국어, हिन्दी, Bahasa Indonesia, Italiano, Українська, Magyar.
How ABX works, why we match loudness, can you trust a browser test, how we're different from hi-res/DSD stuff.
- Pick what you're listening on - headphones, speakers, sound card (models optional, chill)
- Listen to A, B, and X - answer: X = A or X = B?
- Get your result - your bitrate threshold + a link to flex (or cope)
- Wanna go again? Different genre, different gear - your call 🔁
Usually takes a few minutes. Less time than arguing about FLAC on Reddit.
- Music nerds & audiophiles - prove you hear what you pay for (or don't)
- Streaming listeners - do you need lossless or is 320 kbps enough? Let's find out
- Headphone owners - see how different gear changes your threshold
- Curious people - quick honest experiment, no foobar2000 install required
ABXtest isn't a lab-grade reference chain. It's a real-life screening test: Spotify, YouTube, podcasts, your headphones, your browser. For hardcore audiophile ABX, foobar2000 + foo_abx exists. For "MP3 vs lossless on my ears" - a web test makes total sense. 💯
