- ATH-M20x BT headphones
- USB-C charging cable

The headphones sport Audio-Technica's classic design language – sturdy, no-frills, and focused on function over form. The large Audio-Technica logos on each earcup leave no doubt about the brand you're sporting.
Build Quality and Comfort
Durability
The ATH-M20x BT features a robust plastic construction with a metal headband reinforcement. While not as premium-feeling as some higher-end models, they're built to withstand the rigors of daily use.
Comfort for Long Sessions
- Padded headband distributes weight evenly
- Oval-shaped earcups provide a comfortable fit
- Synthetic leather earpads offer decent breathability
For extended listening sessions, these headphones remain comfortable, though they may cause some heat build-up after several hours.
Sound Quality: The Heart of the Matter
Frequency Response
The ATH-M20x BT boasts a frequency response of 15-20,000 Hz, which is respectable for headphones in this price range. This translates to:
- Clear, detailed mids
- Crisp highs without harshness
- Balanced bass that doesn't overpower
Soundstage and Imaging
While not as expansive as open-back designs, the ATH-M20x BT provides a decent soundstage for closed-back headphones. Instrument separation is good, allowing you to pick out individual elements in complex mixes.
Codec Support
In 2025, Audio-Technica has expanded the codec support to include:
- SBC (standard)
- AAC (high-quality for iOS devices)
- aptX (added in the latest update)
- LDAC (new addition for hi-res audio)
This broader codec support enhances the wireless audio quality, bringing it closer to wired performance.
Wireless Performance
Bluetooth Connectivity
The ATH-M20x BT uses Bluetooth 5.2, offering:
- Stable connection up to 10 meters
