A bubble-tea case that makes the Surfans T1 a gift

The Surfans T1 starts with the case. It's round, glossy and shaped like a bubble-tea cup, with a clear crystal-ball look that sets it apart from the flip-top boxes most stem earbuds live in. Inside sit two white semi-in-ear buds weighing 3 grams each, linked over Bluetooth 6.0.

Surfans pitches the T1 as a gift, and the design backs that up. The case stands upright on a desk like a little ornament, and pulling a bud out feels a bit like picking a pearl from a cup.

What makes the T1 stand out among open-fit stems:

  • The crystal-ball case. A round, glossy shape about 43.5mm across and 68mm tall.
  • 3-gram buds. Light enough that you forget they're in after a few minutes.
  • Bluetooth 6.0. The newest version in this group of stem earbuds.
  • AAC and SBC. AAC is the codec iPhones prefer, and SBC covers every Android phone.
Gifting tip: the T1 case is round, so it rolls. Pop it into a small box or pouch for wrapping, and it arrives looking as neat as it did on the shelf.

Surfans describes itself as an audio brand with over ten years of experience, and it puts that into a 13mm driver where many cute-case pairs cut corners on sound.

The semi-in-ear shape follows the classic i12 idea: the bud rests in the outer ear rather than sealing the canal. It's airy and comfortable for long listening sessions at work, on trips or on the sofa, and you stay aware of the room around you.

For more cheerful finishes and pastel cases, the colors guide rounds up the prettiest pairs by shade.

Bluetooth 6.0 and a 13mm bio-diaphragm in a 3g bud

Under the cute shell, the T1 carries a 13mm dynamic driver with a bio-diaphragm and a pure copper voice coil. Bio-diaphragms use a thin, stiff cellulose-based film, which helps a driver move quickly and keep detail clean. The maker says the result is fuller sound and better bass than standard buds at the same level.

Open-fit buds always give up some low end compared with sealed tips, since no seal traps the bass. A large 13mm driver narrows that gap, which is why the T1 still sounds lively with pop, podcasts and film soundtracks.

Driver13mm bio-diaphragmClear detail, more bass than tiny drivers
Voice coilPure copperClean, responsive sound
CodecsSBC, AACGood quality on iPhone and Android
MicsDual, AI noise reductionYour voice stays clearer on calls

Bluetooth 6.0 is backward compatible, so the T1 pairs with any phone, tablet or laptop that has Bluetooth. Newer link features only switch on when both ends support them, and most phones today run a 5.x version, so for now the gain is mainly a steady, low-latency connection up to about 10 metres.

Where the T1 shines:

  • Music and podcasts at a desk, where open fit keeps you aware of colleagues.
  • Video calls, with dual mics cleaning up background noise.
  • Travel and relaxing at home, thanks to the 3-gram weight.
  • Shared spaces, where you still want to hear the doorbell.

The title calls it noise cancelling, and that describes the call mics. There is no ANC to quiet a bus or plane for you.

Among the pairs

Where this pair lands

i12 TWS earbuds models by fit and case, September 2026. Highlighted: Surfans T1.

Pair the T1 and make 20 hours stretch

The T1 connects the moment the case opens. On first use, pick it from your phone's Bluetooth menu; after that, lifting the lid is enough. Taps on the buds handle music, calls, volume and the voice assistant.

  1. Charge the case with the included cable before the first listen.
  2. Open the case and lift out both buds.
  3. Choose the T1 in the Bluetooth list on your iPhone, Android phone or laptop.
  4. Try a few taps with a song playing to learn the controls.

If you're new to stem earbuds, the pairing guide walks through each kind of device, and the touch controls cheat card maps every tap.

Battery is the T1's modest side. The total is up to 20 hours with the case, and the case holds up to three extra charges for the buds. That's plenty for a workweek of commutes and desk sessions, but less than the 40-hour-plus pairs with bigger cases.

Habits that get the most from 20 hours:

  • Return the buds to the case whenever you take them out; short top-ups add up.
  • Keep volume moderate; open-fit buds tempt you to turn it up in noisy places.
  • Charge the case overnight once or twice a week, rather than waiting for it to run flat.
  • Carry the cable on long trips, since there's no battery readout on the case.
The maker lists the T1 as water resistant without an IP number. Wipe the buds after a warm day and skip workouts in the rain.

When a bud stops charging or one side goes quiet, the charging guide and the left and right reset cover the fixes.

Surfans T1 against the Miffy TD17 and 1 Hora open fits

The T1 belongs to a small group of open-fit pairs chosen as much for their looks as their specs. Here's how it compares with two gift-friendly favorites and one classic white pair with more hours.

Choose the T1 if:

  • You want the newest Bluetooth version in a pretty case.
  • Light, airy buds matter more than long battery.
  • The gift needs to look special straight out of the box.

The MIPOW Miffy TD17 is the pick for Miffy fans and adds an IPX5 rating for sweaty days. The 1 Hora AUT201 is the simple, budget open fit, and the Jxrev J53 doubles the T1's hours with a battery readout and IPX7.

Before you buy, check that:

  • 20 hours of total battery fits your week.
  • Open fit suits the ears you're buying for; some ears hold these buds better than others.
  • The receiver won't need them for rainy runs.

The T1 comes with a 1-year warranty from Surfans, so keep the box with the gift receipt.

A second thought for gift buyers: think about how the person listens. Someone who spends the day at a desk or on the sofa will love the light, open fit and the case on display. Someone who runs every morning or rides a loud train will get more from a sealed, splash-rated pair, however cute the T1 looks on the shelf.

Quick answers

How long does the Surfans T1 battery last?

Up to 20 hours in total with the case, which holds up to three extra charges for the buds.

Does Bluetooth 6.0 work with my older phone?
