How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want tiny all-day true wireless earbuds with a 10 mm driver and a charging case you can forget in your pocket, choose TPVision Philips TAT2159; if you need a wired in-ear monitor with a detachable cable and a 10 mm dynamic driver built for gaming and critical listening, choose Herdslive Yongse YOLO Owl.
• TPVision Philips TAT2159 — biggest strength: a genuinely pocket-sized true wireless design that still fits a 10 mm dynamic driver, with Bluetooth 5.3, multipoint pairing, touch controls and a case that carries the charge.
• TPVision Philips TAT2159 — biggest trade-off: 6 hours per charge (8 more from the case) and no active noise cancellation — it relies on the AI mic and a snug seal instead.
• Herdslive Yongse YOLO Owl — biggest strength: a wired, tunable in-ear monitor with a 10 mm PU+PEEK composite diaphragm, a three-layer tuning system and a 0.78 2-pin detachable cable you can swap.
• Herdslive Yongse YOLO Owl — biggest trade-off: it is wired only, with a 3.5 mm jack and no battery — so it lives with your phone, laptop or console, not on a run.
• Who each pick is for: the TAT2159 is for people who want wireless freedom, calls and a tiny footprint; the YOLO Owl is for listeners who want a wired, cable-swappable IEM with a fun owl-pattern faceplate.
The TAT2159 is the compact, wireless-first option. Philips calls these its smallest true wireless earbuds yet, and the spec sheet backs up the "tiny but mighty" framing: a 10 mm dynamic driver, a 20 Hz–20 kHz frequency range, and a touch surface you tap on the left earbud to switch on Dynamic Bass. That tap-to-bass trick matters more than it sounds — it lets you pull out low-end at lower volumes without cranking the volume, which is exactly the kind of thing that makes small earbuds feel bigger than they are.
Around that driver, Philips builds a genuinely practical daily package. Bluetooth 5.3 handles stability, and multipoint connectivity lets you stay connected to two devices at once — music from your phone while smartwatch notifications come through. The AI microphone uses an algorithm to filter out surrounding noise for calls, which is the kind of feature you notice on a windy walk or in a coffee shop. Battery is 6 hours per charge with 8 more in the case, and a 15-minute top-up buys you an extra hour. Four sizes of tips are included, the fit is anti-slip, and the IPX4 rating covers sweat and light splashes.
Herdslive Yongse YOLO Owl: Who It's For
The YOLO Owl is the opposite philosophy: wired, tunable, and unapologetically an in-ear monitor. Its 10 mm driver uses a PU+PEEK composite diaphragm, driven by an imported large black copper-clad aluminum voice coil acting on a nickel-plated diaphragm. Herdslive pairs that with a dual magnetic, dual cavity unit — a design intended to purify and improve sound across all frequency bands. In practice, the spec language points to a V-shaped-ish, energetic tuning: strong, full bass, clear midrange, and highs that are crisp without turning harsh.
The tuning story goes further than most budget IEMs. A multi-layer tuning system works across the sound guide tube, front cavity, side hole and second cavity, with three layers of tuning cloth doing precise audio control. The cavity itself is high-density PC material chosen to suppress diffuse reflections of sound waves inside the shell — the kind of detail you normally only see discussed in audiophile circles. The cable is 5N OCC, soft and durable, and the 0.78 2-pin detachable connector means you can swap cables later if you want a different feel or a replacement.
The look is deliberate too: a silver faceplate with an anime owl pattern, which Herdslive says stays comfortable for long sessions. It's a wired 3.5 mm design with a mic, and the listed compatible devices cover laptops, desktops, gaming consoles, tablets and phones — so it's equally at home plugged into a controller or a laptop. Who should buy it: gamers, IEM-curious listeners, and anyone who prefers a cable and wants to swap it. Who should skip it: if you want wireless freedom, a charging case, or water resistance for sweaty workouts, this is the wrong tool — there's no battery and no IP rating listed.

If I had to pick one for most people, I'd buy the TPVision Philips TAT2159. In my opinion, the combination of a 10 mm driver, Bluetooth 5.3, multipoint, an AI mic for calls and a genuinely tiny case covers more of everyday life than a wired IEM can. The 6-hour playtime plus 8 hours in the case and the 15-minute quick charge are enough for a normal day, and the IPX4 rating means you don't have to baby them. I'd only steer you to the Herdslive Yongse YOLO Owl if you specifically want a wired, cable-swappable IEM — for gaming, for desktop listening, or because you like the idea of a tunable, repairable pair. That's a real preference, not a downgrade; it's just a different job.
A 10 mm driver means the earbud's speaker diaphragm measures 10 millimeters across. Both products here use a 10 mm dynamic driver, which is a common size that tends to move more air than smaller drivers — that's why the TAT2159 can push "dynamic bass" and the YOLO Owl can deliver full low-end.
Is 10mm driver good for earbuds?
Neither product here uses a 6 mm driver, so it's not a choice you have to make between these two. As a general rule, a smaller driver like 6 mm can still sound clean in a well-tuned shell, but it usually has less physical punch than a 10 mm unit — which is exactly why both of these models went with 10 mm.
For gaming, I'd lean toward the Herdslive Yongse YOLO Owl. It's wired over a 3.5 mm jack with listed compatibility for gaming consoles, desktops and laptops, so there's no Bluetooth latency to worry about, and the detachable cable means you can swap in a different one. The TAT2159 is the more convenient all-rounder, but wired still wins for low-latency play.
Yes — both are budget-tier products, and the value math changes with whatever the current price is.
