How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds that disappear inside your ear for sleeping, all-day office wear and quiet hunting sits, choose Ttbesmi Mini Invisible Earbuds; if you need a bigger, bass-forward semi in-ear sound with environmental noise cancelling on calls and a low latency mode, choose Defunc True LITE II. That is the whole decision in one line. Everything below is me walking through why, spec by spec, because both are marketed as "low latency" bluetooth headphones but they are built for two completely different people.
• Ttbesmi's biggest strength: a genuinely tiny, nude-colored, peanut-sized in-ear shell at roughly 0.08 oz per bud, so it vanishes from the front and never builds up pressure during long sessions — the closest thing here to a true sleep/invisible earbud.
• Ttbesmi's biggest trade-off: modest audio hardware — a 16 ohm dynamic driver, 4 to 5 hours per charge (30 hours total with the case), and sound isolation only, with no active noise cancellation and no app.
• Defunc's biggest strength: a 13 mm bass driver, Bluetooth 6.0, ENC clear calls, passive noise cancellation and up to 20 hours of playtime — far more "headphone" than "ear plug."
• Defunc's biggest trade-off: a semi in-ear bud shape that sits in the ear rather than hiding in it, so it is visible, and its 20-hour figure is total playtime rather than a huge single-charge number.
• Choose Ttbesmi if discretion, weight and sleeping comfort matter more than bass and call clarity.
• Choose Defunc if you want proper stereo music, clearer voice pickup and a low latency mode for video and gaming.
The Ttbesmi Mini is built around one idea: make the earbud so small and so close to skin tone that nobody knows it is there. At about 0.08 oz per bud and a rounded tip roughly the size of a peanut, it slides fully into the ear canal and stays invisible from the front. The color is listed as nude, and so is the charging case, which is a deliberate choice — this is an earbud designed to be overlooked. If you work in an open office, sit in a shared space, or want to listen without announcing it, that design detail does more for you than any spec sheet number.
Who should buy it: sleepers, side sleepers, office workers, anyone with small ear canals who finds normal buds fall out, and hunters who want something that stays put and stays quiet. Who should skip it: if you want deep bass, app-based EQ, waterproofing for heavy sweat, or a low latency mode you can actually toggle, this is not the pair — the low latency benefit here comes from Bluetooth 5.3's steadier signal, not from a dedicated gaming mode.
Defunc True LITE II: Who It's For
The Defunc True LITE II is the opposite philosophy. It is a semi in-ear bud — it rests at the entrance of the ear rather than burying itself — with a 13 mm dynamic driver tuned as a bass driver at 16 ohm. That single number tells you a lot: 13 mm is a large driver for a compact earbud, and Defunc explicitly positions it for rich bass, clear vocals and balanced stereo. If you have been hunting for the best extra bass headset for hunting, this is the one of the two that actually chases bass.
The spec list is modern and complete. Bluetooth 6.0, ENC (environmental noise cancelling) for calls, low latency performance called out as a feature, IPX4 water resistance, passive noise cancellation, touch controls, and up to 20 hours of playtime. There is also AI app support, which is where you would go for any tuning or firmware-side adjustments. The carrying case is small — about 5 cm by 2.5 cm by 5 cm and 35 g — so it disappears in a pocket even if the buds do not disappear in your ears. It is designed in Sweden with a deliberately minimal Scandinavian look, and it comes in Pink.
Who should buy it: commuters, students, casual gamers and movie watchers who want a real low latency mode, people who take a lot of calls and want their voice to come through clearly, and anyone who wants a proper hifi stereo wireless headset for hunting sessions where audio quality matters more than stealth. Who should skip it: side sleepers and anyone who needs a bud that is genuinely invisible. A semi in-ear bud with passive noise cancellation is not going to vanish, and it is not shaped for pressing into a pillow.
• Best for sleeping and side sleeping → Ttbesmi Mini Invisible Earbuds. Roughly 0.08 oz per bud and a rounded tip designed to sit flush in the canal.
• Best for invisible, low-profile wear → Ttbesmi Mini Invisible Earbuds. Nude buds and a nude case, peanut-sized, hidden from the front.
• Best for bass and music quality → Defunc True LITE II. A 13 mm bass driver versus a standard 16 ohm dynamic driver.
• Best for calls → Defunc True LITE II. ENC clear calls, plus touch controls and an AI app.
• Best single-charge stamina → Ttbesmi Mini Invisible Earbuds. 4 to 5 hours per charge, which is longer than the Defunc's 20 hours split across the case.
• Best total playtime → Defunc True LITE II. Up to 20 hours of total playtime with the case.
• Best for sweat, rain and workouts → Defunc True LITE II. IPX4 water resistance; Ttbesmi's sheet does not list a water rating.
• Best for hunting, quiet and discreet → Ttbesmi Mini Invisible Earbuds. Light, secure, isolation-based, and it will not flash a color or a logo at whatever you are watching.
If I were buying for myself and my priority was sleeping, working unnoticed, or sitting still in a blind for hours without anything pinching my ear, I would buy the Ttbesmi Mini Invisible Earbuds. The 0.08 oz weight, the nude color and the flush fit are the entire point, and nothing on the Defunc side replicates that. But if I wanted headphones for hunting that double as everyday music and call earbuds — bass, ENC calls, IPX4 and a low latency mode — I would buy the Defunc True LITE II without hesitating. In my opinion these are not competitors so much as two answers to two different questions, and the deciding one is whether you value invisibility or sound.
how to make bluetooth headphones low latency
Latency comes from the Bluetooth version and the codec, plus any low latency mode the maker builds in. Both of these use modern Bluetooth — 5.3 on the Ttbesmi, 6.0 on the Defunc — and the Defunc explicitly lists low latency performance as a feature, so it is the more direct answer if reducing audio delay is your goal.
do bluetooth headphones have latency
Yes. All wireless Bluetooth audio introduces some delay between the source and your ear, which is why lip-sync can look slightly off in video. Newer Bluetooth versions and dedicated low latency modes reduce it, which is why the Defunc True LITE II advertises that feature while the Ttbesmi leans on Bluetooth 5.3's steadier signal transmission.
how to get low latency on bluetooth headphones
Use the lowest-latency mode your earbuds offer, keep the source device close — both of these are rated to about 10 meters — and avoid heavy interference between phone and buds. On the Defunc True LITE II, check the AI app for any audio mode settings; on the Ttbesmi Mini, the benefit is simply the Bluetooth 5.3 chip doing its job.
how to get low latency on bluetooth headphones windows 11
On Windows 11 the delay is mostly decided by your PC's Bluetooth adapter and codec support, not the earbuds alone. Pair the buds, then in Sound settings pick the stereo playback device rather than a hands-free profile, since the hands-free profile is the one that adds the most noticeable lag.
