Black stem earbuds with active noise cancelling and a charging case that has its own touchscreen for volume, tracks, calls, noise modes and finding a lost bud.
The CuiSuto M28 moves the controls from your phone to the case. Its charging case carries a small touchscreen that turns the volume up or down, skips tracks, handles calls, switches noise cancelling modes and helps you find a missing bud. The buds themselves are black in-ear stems with silicone tips, linked over Bluetooth 5.4.
A screen on the case sounds like a gimmick until you try it with gloves on, or with the phone buried in a backpack. Tap the case, the song changes, and the phone stays put.
What the M28's screen handles for you:
The styling leans premium. The stems have smooth curves and a metallic finish, and the pocket-sized case keeps its screen facing up when it rests on a table.
The screen also doubles as a small clock, so a glance at the case on your desk tells you the time as well as the battery. Battery reaches up to 60 hours with the case, one of the higher totals among touchscreen pairs, so the screen doesn't come at the cost of hours. The case charges over a USB-C cable.

Active noise cancelling is the M28's other headline. Microphones listen to the sound around you and the drivers play an opposite signal to cancel it, which works best on steady rumble like engines, air conditioning and road noise. The M28 lets you choose between four noise cancelling modes from the case.
Paired with the seal from silicone tips, ANC makes a real difference on a bus or plane. Voices and sudden clatters get through more than steady hum does, which is how ANC behaves on nearly every pair.
How the M28's sound settings fit different days:
| Setting | When it helps |
|---|---|
| ANC on | Flights, trains, open offices |
| Lighter or off | Walks near traffic, where you need to hear what's around you |
| EQ presets | Bass for workouts, clearer voices for podcasts |
The 13mm dynamic drivers cover 20Hz to 20kHz, and the 13-ohm impedance means any phone drives them easily. Five EQ presets let you tilt the sound toward bass, vocals or a flatter balance without an app.
Where the M28 makes the most sense:
ANC also helps on calls. With less background rumble in your ears, it's easier to hear the other person, and the maker says the noise cancelling keeps calls clear in busy places. For a phone-heavy day at a desk, set the case beside the keyboard and use it to answer.
Keep in mind that ANC uses some extra battery. Running it all day will pull the real total below the 60-hour figure, so switch it off on quiet walks to stretch the charge.
Setting up the M28 is the same as any stem pair: open the case, let the buds wake, and pick them in your phone's Bluetooth menu. The screen comes into its own once they're connected, so give it a first charge and a quick tour before heading out.
Pairing details for each type of device sit in the pairing guide. If only one side plays after setup, the left and right reset relinks them in a minute.
Fit tips for the in-ear design:
Each bud weighs about 3.7 grams, light enough for long sessions. The maker describes the buds as sweat- and dust-resistant, which covers gym sessions and walks, though no IP number is given, so keep them away from showers and heavy rain.
Touchscreen cases have become a small family of their own among stem earbuds. The M28 leads its group on battery, while the others trade hours for extras like an IPX7 rating or ENC call mics. Here's how the three compare.
| Spec | CuiSuto M28 | T21 Touchscreen | Bucephalus T20 |
|---|---|---|---|
| Bluetooth | 5.4 | 5.3 | 5.4 |
| With case | 60h | 40h | 48h |
| Driver | 13mm | 14.2mm | 13mm |
| Water | Sweat-resistant | IPX7 | Not listed |
| Noise | ANC, 4 modes | Hybrid ANC, transparency | ANC |
Pick the M28 if:
The T21 Touchscreen suits gym-goers with its IPX7 rating and transparency mode, and it adds a camera remote on the case. The Bucephalus T20 brings ENC call mics for people who spend their day on the phone.
Three things to be sure of:
Screen cases no longer sit only at the top of the range. The price bands show where screen pairs start and what each step up adds.
One more way to decide: think about where your phone lives. If it's always in your hand, bud taps are enough and a plain LED case will do. If it spends the day in a bag, a desk drawer or a jacket on the back of a chair, the M28's screen saves a lot of digging.
It changes the volume, skips tracks, handles calls, switches between four noise cancelling modes and helps you find a lost bud, all without your phone.
Yes. The M28 has active noise cancelling with four adjustable modes, set from the case. It works best on steady noise like engines and air conditioning.
Up to 60 hours with the case. Using ANC all the time pulls that figure down, so switch it off when you don't need it.
The maker calls it sweat- and dust-resistant but gives no IP number. It's fine for workouts; keep it away from showers, pools and heavy rain.
