The Audio-Technica ATH-S220BT is a lightweight, closed-back on-ear Bluetooth headphone with a manufacturer-rated maximum of about 60 hours of continuous music playback. It supports Bluetooth 5.0, SBC audio, two-device multipoint pairing, a low-latency mode, voice-assistant access and a wired fallback cable.
Those are manufacturer specifications and feature descriptions, not independent test results. There is no verified measurement here for sound signature, comfort, call quality, latency, multipoint switching speed or real-world battery runtime. Treat the ATH-S220BT as a feature-rich, travel-friendly model on paper, and check local stock because Audio-Technica’s Japanese page marks it discontinued in Japan.
What the ATH-S220BT is
The ATH-S220BT is a closed-back, on-ear wireless headphone released in Japan on June 25, 2021. Its earcups sit on the ears rather than surrounding them, and the listed mass is approximately 180 g. Audio-Technica positions it around long battery life, everyday Bluetooth convenience and the option to keep listening through a cable.
“On-ear” describes the physical fit, not a guaranteed comfort level. Ear shape, glasses, hairstyle, head size and preferred clamping pressure all affect whether an on-ear design works for you. No independent fit or comfort test was established for this model, so the 180 g figure should be treated as a weight specification rather than proof that it will feel comfortable during a full workday.

ATH-S220BT specifications at a glance
| Specification | ATH-S220BT detail | What the figure does—and does not—tell you |
|---|---|---|
| Design | Closed-back, dynamic, on-ear | Closed cups can reduce sound leakage compared with an open design, but isolation and comfort were not independently measured. |
| Driver diameter | 40 mm | A driver-size specification; it does not predict a particular tonal balance or sound quality. |
| Frequency response | 5–32,000 Hz | The manufacturer’s stated range, not evidence that you will hear every frequency equally or that the headphone sounds better. |
| Sensitivity | 105 dB/mW | A published electrical/acoustic specification; listening level still depends on the source and recording. |
| Impedance | 32 ohms | The stated load for the headphone. Actual loudness depends on the connected device and its output. |
| Bluetooth | Version 5.0 | Wireless version listed in the manual; it does not by itself guarantee a particular range in every room. |
| Bluetooth profiles | A2DP, AVRCP, HFP and HSP | These cover stereo music, media controls and hands-free calling functions supported by the documented implementation. |
| Bluetooth codec | SBC | SBC is the only codec documented in the manual. Do not assume AAC, aptX or LDAC support. |
| Advertised range | Approximately 10 m line of sight | A stated unobstructed-distance figure; walls, interference and body position can reduce practical range. |
| Maximum battery claim | Approximately 60 hours of continuous music playback | A conditional Audio-Technica claim, not an independently measured runtime. |
| Charging time | Approximately four hours | The manufacturer’s stated charging duration; cable, charger and battery condition can affect the result. |
| Weight | Approximately 180 g | Listed product mass; it does not establish clamp force or long-session comfort. |
| Included cables | 30 cm USB-A-to-USB-C charging cable; 1.2 m cable with in-line microphone and remote | The analog cable provides a wired fallback and an in-line control/microphone assembly. |

Battery life: an impressive claim that needs context
Audio-Technica advertises a maximum of approximately 60 hours of continuous music playback. The word “maximum” matters: it is a manufacturer claim under stated conditions, not a result measured by an independent reviewer. Volume, wireless conditions, temperature, battery age and how often you use calls or other functions can change runtime.
The listed charging time is approximately four hours. Because the battery figure and charging duration are both conditional specifications, use them for planning rather than as a guarantee. If you need a precise runtime for a flight, shift or recurring commute, test a fully charged unit with your own phone, listening level and usage pattern before relying on it.
Charging procedure
- Connect the supplied 30 cm USB-A-to-USB-C cable to the headphone’s USB-C charging port.
- Connect the USB-A end to a compatible powered USB port or charger.
- Allow approximately four hours for the manufacturer’s stated charging period; use the status indicator and the manual’s instructions to confirm charging behavior.
- Disconnect the cable before using the headphones wirelessly. Keep the charging port dry and avoid forcing the connector.
The published material does not establish a quick-charge feature, a replaceable internal battery or a measured standby time. Do not infer any of those capabilities from the 60-hour headline.

Bluetooth, SBC and the wireless feature set
Codec and profiles
The manual documents Bluetooth 5.0 with the SBC codec and the A2DP, AVRCP, HFP and HSP profiles. SBC is a standard Bluetooth audio codec and is the only codec confirmed for this model. The available documentation does not list AAC, aptX, aptX HD, Adaptive or LDAC, so a phone showing those options for other headphones should not be taken as evidence that the ATH-S220BT supports them.
A2DP handles stereo music, AVRCP supports media-control functions, and HFP/HSP cover hands-free communication. The profile list describes compatibility functions; it does not provide a latency measurement, microphone-quality rating or guarantee that every device will expose identical controls.
Pairing and multipoint
Audio-Technica advertises multipoint pairing for two simultaneous devices—for example, a smartphone and a PC. The Hong Kong product description says, “Multipoint pairing allows you to connect to two devices, such as a smartphone and PC, simultaneously.” That establishes the intended two-device capability, but no independent test established how quickly switching occurs, which device gets priority, or how reliably calls interrupt music.

Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →- With the headphones powered off, press and hold the power/pairing control until the indicator enters pairing mode, following the manual’s exact timing.
- On the first source, open its Bluetooth settings, select ATH-S220BT and complete pairing.
- Disconnect or pause that source as directed by the manual, then place the headphones back into pairing mode and pair the second source.
- Reconnect the first source if necessary and confirm that both devices show an active connection before testing calls, notifications and media playback.
Operating-system menus and pairing prompts differ. If only one device remains connected, remove the saved ATH-S220BT entry from both sources, restart Bluetooth, and repeat the sequence rather than assuming the hardware is defective.

Low-latency mode
The product page advertises a low-latency mode for video and games. It does not publish a latency figure, codec-specific delay, supported game systems or an independent test. The feature may help synchronization in some setups, but you should not treat “low latency” as proof of imperceptible delay. Test speech, lip movement and game effects on the device you actually use.
Fit, comfort and physical design
The ATH-S220BT is an on-ear headphone weighing approximately 180 g. That relatively low listed mass may appeal to people who dislike heavier over-ear models, while the smaller earcups may suit users who want a compact design. Neither point predicts individual comfort: pad pressure, headband shape, ear contact and heat are personal variables.
The cups are closed-back and use 40 mm dynamic drivers. Closed-back construction describes the enclosure; it does not establish a measured isolation level, noise-cancellation performance or sound signature. There is no verified claim of active noise cancellation or water resistance in the supplied documentation, so do not buy it expecting either feature.
Earpads and service parts
Audio-Technica identifies HP-S220BT replacement earpads. Replacement pads can be useful when the original cushions wear, but pad material and thickness can alter the fit and the acoustic seal. The product information also lists a replacement microphone cable as a separate accessory; confirm the exact part number and local availability before ordering.

- 40 mm drivers with rare earth magnets and copper clad aluminum wire voice coils
- Tuned for enhanced low frequency performance
- Circumaural design contours around the ears for excellent sound isolation in loud environments
- Convenient single side cable exit
Wired listening, controls and calls
The supplied 1.2 m cable has an in-line microphone and remote, giving the ATH-S220BT a wired fallback when Bluetooth is unavailable or wireless use is not allowed. The documentation does not establish whether every control function works identically in wired mode, whether the battery must be charged for microphone operation, or whether the cable carries audio from every source. Check the manual and your device’s jack or adapter requirements.
Wireless operation includes a built-in microphone for calls, voice-assistant access and support for the hands-free profiles. Those are feature descriptions, not a call-quality test. Room acoustics, wind, phone processing and microphone placement can all affect how callers hear you. If reliable voice communication is critical, test a call in the locations where you plan to use the headphone.
What is—and is not—known about sound
The published specifications give a 40 mm dynamic driver, 5–32,000 Hz stated frequency response, 105 dB/mW sensitivity and 32-ohm impedance. They do not establish bass quantity, treble balance, detail, distortion, channel matching or suitability for a particular music genre. Frequency-response endpoints are especially easy to overinterpret: they describe a specification range, not a graph of the headphone’s actual tonal balance at your ears.

The headphone will not pair
- Make sure it is in pairing mode rather than merely powered on.
- Delete old ATH-S220BT entries from nearby devices, then restart Bluetooth.
- Move away from other active Bluetooth equipment and retry within the stated approximate 10 m line-of-sight range.
- Charge the headphone and repeat the manual’s reset or initialization procedure if pairing records appear stuck.
Only one multipoint device stays connected
- Verify that both sources completed pairing; a device listed as “saved” is not necessarily connected.
- Pause media on the first source before connecting the second.
- Disable automatic Bluetooth switching features on the sources while testing.
- Forget the headphone on both devices and rebuild the two-device pairing in sequence.
Audio cuts out
- Keep the source within the approximate 10 m line-of-sight specification and remove body or wall obstructions.
- Move away from congested 2.4 GHz wireless areas.
- Check the source’s battery, volume and output selection.
- Try the supplied cable to distinguish a Bluetooth problem from a general playback problem.
Calls sound poor
- Confirm that the operating system selected the ATH-S220BT hands-free profile for both input and output.
- Move the microphone away from rubbing clothing and reduce wind noise.
- Run a short test call in the same room and network conditions in which you normally work.
Availability, colors and regional differences
The Japanese product page lists the ATH-S220BT as discontinued in Japan. That label is geographically limited; it does not prove that every market has stopped selling the model. Check local retailers, warranty terms and return policies before purchasing, especially for old stock.
Japanese model/color codes listed by Audio-Technica are BK, BRD, NBG and WH. The Hong Kong page lists BK, NBG and WH, so color selection is regional rather than universal. Release date, discontinuation status and color availability should be confirmed on the page serving your country.

How it compares on the questions that matter
No competing model was validated alongside the ATH-S220BT, so naming a “best alternative” or claiming that one model outperforms another would be unsupported. Use the following checklist when comparing it with any current headphone:
| Decision factor | ATH-S220BT evidence | What to verify in another model |
|---|---|---|
| Fit | On-ear, approximately 180 g | Whether you prefer on-ear pressure or an over-ear seal; pad dimensions and return policy. |
| Battery | Approximately 60 hours maximum, manufacturer claim | Independent runtime at a stated volume and codec, plus charging time and quick-charge behavior. |
| Codec | SBC documented | Whether AAC, aptX or another codec is actually supported by both headphone and source. |
| Multipoint | Advertised for two devices | Measured switching speed, call priority and behavior when both sources play audio. |
| Latency | Low-latency mode advertised | Measured delay for video and games, and whether the mode changes codec or audio quality. |
| Calls | Built-in microphone and hands-free profiles | Independent voice recordings, noise handling and microphone performance outdoors. |
| Support | HP-S220BT earpads and a microphone cable are listed accessories | Local spare-part stock, warranty length and service availability. |
| Price | Current price not established here | Local currency price, taxes, shipping and return terms at the time you buy. |
Who should consider the ATH-S220BT?
A reasonable match
- You want a lightweight on-ear design rather than a larger over-ear headphone.
- You value a long manufacturer battery claim and can accept that it is not independently verified.
- You use a phone and computer and want documented two-device multipoint.
- You need a cable option for aircraft seats, computers or devices without Bluetooth.
- SBC is sufficient for your sources and you do not require a higher-tier codec.
- You are comfortable checking regional stock and warranty details because Japanese listings show discontinuation.
Look elsewhere if these are requirements
- You need active noise cancellation, water resistance or a certified protection rating.
- You require a measured low-latency result for competitive gaming or professional monitoring.
- You need AAC, aptX, LDAC or another codec that is not documented for this model.
- You require independently verified battery, comfort, isolation or microphone measurements before buying.
- You strongly prefer over-ear cups or know that on-ear pressure bothers you.
Verdict
The ATH-S220BT’s strongest documented case is practical rather than audiophile: approximately 180 g, a claimed maximum 60-hour playback figure, Bluetooth 5.0 with SBC, two-device multipoint, a low-latency mode and a supplied wired microphone cable. Those features make it worth considering when your priorities are portability and flexibility.
The qualification is equally important. The battery figure, multipoint behavior and low-latency benefit are manufacturer claims without independent measurements in the available evidence; comfort, sound, call quality and isolation are not established by published testing here. Confirm the fit, local price, warranty and stock in your region before committing, particularly because the Japanese listing marks the model discontinued.
