If you want a neckband that stays together and can run for up to 20 hours for Switch sessions, choose Avantree NB16-Q; if you need compact, semi-in-ear earbuds with a charging case and IPX4 water resistance, choose Defunc True LITE II. For Switch use, my pick is the Avantree if you value its wearable neckband design; the Defunc is the more portable everyday option.
• Avantree NB16-Q’s biggest strength: A neckband keeps the earbuds connected when they are out of your ears, and battery life is up to 20 hours. Trade-off: It is a neckband rather than a compact, case-based pair.
• Defunc True LITE II’s biggest strength: Semi-in-ear buds, a charging case, Bluetooth 6.0, and IPX4 water resistance make a compact everyday package. Trade-off: Its stated 20-hour playtime is total playtime, not an individual charge figure.
• For Switch sessions: Choose Avantree if you want a neckband that stays around your neck between uses; choose Defunc if you prefer separate buds and a charging case.
• For calls and everyday listening: Defunc lists ENC clear calls and low latency; Avantree lists built-in call controls and aptX Adaptive support.
• Who each is for: Avantree suits listeners who prioritize a secure, hard-to-misplace design and long listening sessions. Defunc suits listeners who want lightweight, semi-in-ear earbuds with a case and water resistance.
The NB16-Q is a Bluetooth 5.2 neckband earbud set with Qualcomm aptX Adaptive support. Its defining practical feature is the band: when you take the earbuds out, they remain joined and rest around your neck instead of becoming two separate pieces to put away. Built-in magnets help hold the earbuds together when not in use.

That design makes the Avantree a sensible choice for Switch players who expect to pause often, move around, or take one or both earbuds out between sessions. Up to 20 hours of listening per charge also gives it a clear use case for long stretches without planning around frequent recharging. Built-in controls handle volume, playback, and calls.
Defunc takes a more compact, case-based approach. The True LITE II uses a semi-in-ear fit and includes a charging case. Its listed Bluetooth version is 6.0, and it has a 13 mm dynamic driver. The product information also lists touch controls, ENC clear calls, and low-latency performance.
For Switch owners, the Defunc may be a better match if you want buds you can store away between sessions rather than a band around your neck. Its semi-in-ear style is also the relevant distinction for shoppers searching for comfortable true wireless earbuds for Switch: it offers a different wearing design from Avantree’s in-ear neckband buds. The sheet describes it as lightweight, but fit remains personal, so the semi-in-ear shape is a preference to weigh rather than a guarantee of comfort for everyone.
The trade-offs are worth noting. Its up-to-20-hour figure is described as total playtime, not as listening time from one charge. It lists IPX4 water resistance, which is useful for everyday exposure to splashes, but that does not make it a product to submerge. The supplied facts do not identify a dedicated Switch mode or give a specific Switch compatibility guarantee, so I would not treat its low-latency feature as proof of a particular gaming experience.
Side-by-Side: Which Should You Choose?
• Best for a neckband you can leave around your neck between uses → Avantree NB16-Q. The band joins the earbuds, and magnets help keep them together when they are not in use.
• Best stated listening time per charge → Avantree NB16-Q. It specifies up to 20 hours per charge. Defunc lists up to 20 hours total, without stating how much playback comes from a single charge.
• Best fit for someone who prefers semi-in-ear buds → Defunc True LITE II. Avantree is described as an in-ear neckband design.
• Best for aptX Adaptive support → Avantree NB16-Q. Its listed audio codecs include aptX Adaptive, aptX, and SBC.
• Best for listed water resistance → Defunc True LITE II. Its specification lists IPX4 water resistance; the Avantree sheet does not list an IP rating.
• Best for shoppers seeking ear clip headphones for Switch → Neither is described as an ear-clip design. Avantree is an in-ear neckband set, and Defunc is semi-in-ear. Choose based on those actual fits rather than the ear-clip label.
• Best for listed call and latency features → Defunc True LITE II. It specifically lists ENC clear calls and low latency, while Avantree lists built-in controls for managing calls.
I would choose the Avantree NB16-Q for Switch if I wanted a pair that stays connected around my neck when I pause or take the earbuds out, plus up to 20 hours per charge. That combination is its clearest advantage over a compact case-based design.
If I wanted semi-in-ear buds, a charging case, or IPX4 water resistance, I would choose the Defunc instead. For my Switch use case, though, the Avantree’s neckband is the more useful distinction.
FAQ
I’d lean toward the Avantree if a neckband and up to 20 hours per charge matter most. Defunc offers a semi-in-ear design, charging case, and listed low-latency feature, but the supplied specifications do not state a dedicated Switch mode for either model.
The listed features do not specify a transparency mode. Its semi-in-ear design is distinct from an open-ear or ear-clip design, so I would not buy it expecting a documented transparency feature.
Not with the older 4186 or 41866 versions, according to the compatibility details. The NB16-Q is listed as compatible with Audikast 3, 4186-Q, and 41866-Q; check compatibility before pairing it with a transmitter.
