Stem earbuds whose case has its own color touchscreen: change songs, turn it up, switch noise cancelling and find a lost bud without unlocking your phone.
The Bucephalus T20 puts a small color touchscreen on the front of its charging case, and that screen becomes a remote for the buds. You can turn the volume up, skip or go back a song, answer a call and switch listening modes with a swipe and a tap on the case. No app to install, no phone to unlock.
The screen also shows the battery left in each bud and in the case as percentages, so a quick glance before you leave the house tells you whether to charge.
What the T20 case can do from its screen:
The buds keep their own touch controls too, so you can still tap to pause when the case is in a bag. The usual stem-bud tap patterns are on the touch-control cheat card, and the screen menus follow the same functions.
For someone buying a first pair, the screen also makes things less mysterious. There are no blinking-light codes to decode: the case tells you in words and numbers what the buds are doing.

The T20 carries ANC, active noise cancelling, which uses microphones to hear steady outside noise and play an opposite sound wave to cancel much of it. That is different from most budget stem buds, which only block noise with their tips.
ANC works best on low, constant sounds: the hum of a plane, the rumble of a bus engine, an air-conditioning unit. It does less against sudden sounds such as voices or a door slamming, and the silicone tips help there by sealing the ear.
When to switch modes on the case screen:
Noise cancelling uses a bit of extra power, which is part of why Bucephalus rates the buds at up to 6 hours per charge. The case holds enough for a total of 48 hours, and a full case charge takes about 1.5 hours.
A good habit with ANC pairs is to switch noise cancelling off when you only need background music at a desk. The buds last longer between charges, and you still hear a colleague who stops by. Turn it back on for the ride home.
The T20 links over Bluetooth 5.4 to iPhones, Android phones and tablets at up to about 33 feet, with a delay of around 60 milliseconds. That keeps voices in sync on videos. The pairing steps show how to connect the first time, and the screen confirms when both buds are linked.
Plenty of budget earbuds give you one fixed sound. The T20 ships with five EQ modes you pick from the case screen: Bass, Rock, Pop, Classical and Jazz. Each one shifts the balance of the 13mm drivers to suit a style of music.
You do not need an app for any of this, which keeps things simple on a phone that is short on storage. Try each preset with a song you know well, then leave it on the one you like best.
Like every sealed bud, the T20 needs a good tip fit for the EQ to make sense. If the Bass preset still sounds thin, try a larger tip before blaming the drivers. A proper seal also makes ANC far more effective.
Presets also help with different content. Podcasts and audiobooks usually sound clearest on Pop, which lifts voices, while films on a tablet often suit Bass for explosions and scores.
The case is about 3 × 2.5 × 1.5 inches and 1.5 ounces, a little larger than a plain case because of the screen. It still fits a jacket pocket. Keep it in a separate pocket from keys so the screen stays scratch-free.
The T20 is one of several stem-earbud pairs with a screen on the case. All of them offer noise cancelling from the screen. The T20's extras are five EQ presets and a camera remote; the others win on battery or water resistance, so the right one depends on how you listen.

How to choose:
Like the idea of a smart case but mostly want long, sweat-proof listening? A digit-display pair such as the BESNOOW I53 or the Btootos A90 Pro covers that at a gentler price level. For a look at how touchscreen cases compare across price bands, see the i12 price bands.
One more thing to think about is how you carry the case. A screen case is a small gadget in its own right, so it pays to keep it out of the pocket that holds your keys or coins. Many owners slip it into a soft pouch or a separate jacket pocket, and the screen stays clear and easy to read for years.
For commuters who want quiet on the train and hate fiddling with their phone, the T20 is a fun and practical pick.
Change volume, play, pause and skip, answer calls, switch listening modes and EQ, help find the buds and act as a camera remote.
No. Every setting, including noise cancelling and the five EQ presets, is on the case screen.
Yes. It has ANC for listening and ENC to keep your voice clear for callers.
Up to 6 hours per charge and up to 48 hours with the case. The case recharges in about 1.5 hours.
Bucephalus does not state a water rating, so keep it away from heavy sweat and rain.
