How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to upgrade the earbuds you already own with a better seal and a more comfortable fit, choose Dekoni Audio Bulletz TWS Memory; if you need a complete pair of kid-friendly wireless earbuds with a playful charging case and long battery life, choose AMAFACE Kids.
• Dekoni Audio Bulletz TWS Memory's biggest strength: slow-rebound memory foam tips with a universal 4.9mm bore that seal your ear canal, boost bass and passive isolation, and still fit inside most true wireless charging cases.
• Dekoni Audio Bulletz TWS Memory's biggest trade-off: it is not a headphone at all — it is a set of replacement tips, so it does nothing for you unless you already own compatible in-ear earbuds.
• AMAFACE Kids' biggest strength: a full self-contained package — earbuds, a kitty-shaped charging case, USB-C cable and three ear tip sizes — with roughly 6 hours per charge and up to 30 hours total via the case.
• AMAFACE Kids' biggest trade-off: the feature set is aimed at casual listeners and kids, so it leans on a cute cartoon theme and touch controls rather than audiophile tuning or premium materials.
• Who each pick is for: Dekoni for tinkerers and commuters who want their existing earbuds to feel and sound better; AMAFACE for a child or casual user who wants a ready-to-wear, giftable set out of the box.
Dekoni Audio Bulletz TWS Memory is an accessory, not a device. It is a set of memory foam replacement ear tips built for true wireless earbuds, sold in a three-pack variety covering Small (10.5mm), Medium (12.5mm) and Large (13.4mm). The defining spec is the 4.9mm bore — the same thread size as Dekoni's Mercury line — which lets the tips mount on a wide range of in-ear models. The data sheet specifically lists compatibility with Sennheiser Momentum, Fostex TM2, Beats Powerbeats Pro, Jabra, Jaybird and the Sony WF-1000XM4, so you can check your own model against that list before committing.
What makes these interesting is the low-profile silhouette. Dekoni's own materials explain the design problem: their older Mercury tips were loved by true wireless users, but most of them were too bulky to sit inside a charging case. The TWS series was built to solve exactly that, so the tips keep a slim enough profile to let the earbuds drop back into most cases without force. That single detail is why this product exists, and it is the reason I would point true wireless owners here rather than at generic foam tips.
AMAFACE Kids: Who It's For
AMAFACE Kids is a complete true wireless earbud set with a personality. The headline is the kitty-cat charging case in a cartoon theme, which the data sheet frames as a gift for holidays and birthdays for kids — and honestly, adults who like the look. Inside the box you get the earbuds, the cartoon charging case, a USB-C cable, three ear tips in S, M and L, and a manual. That is a genuinely complete starter kit, and the inclusion of multiple tip sizes matters because fit is the number one reason cheap earbuds get abandoned.
On the spec side, the numbers are modest but reasonable for casual use. Battery life is around 6 hours on a single charge, with the case adding roughly 24 hours more for about 30 hours total, and a full recharge takes about 1.5 hours. The earpieces use a dynamic driver with 16 ohm impedance, which is easy to drive from a phone, and the advertised sound profile is high-fidelity stereo with deep bass and a 3D surround feel. Bluetooth range is listed at 10 meters, and pairing is automatic once you lift the buds out of the case.
The practical features are where this makes sense for its audience. Touch controls handle volume and playback without reaching for a phone, IPX5 water resistance covers sweat and rain, and there is a built-in microphone for calls. The brand backs it with a stated commitment to customer service if anything goes wrong.
Buy these if you want an inexpensive-looking, fun, self-contained pair for a child, a casual listener, or as a gift — the kitty case and cartoon theme do a lot of work here. Skip them if you are chasing critical listening, premium build materials, or a serious noise-cancelling experience; the plastic enclosure and playful design tell you exactly who this is aimed at.
• Best for upgrading earbuds you already own → Dekoni Audio Bulletz TWS Memory. The 4.9mm bore and low-profile shape are purpose-built for true wireless models.
• Best for a complete, ready-to-use package → AMAFACE Kids. Earbuds, charging case, cable and three tip sizes all come in the box.
• Best for battery life → AMAFACE Kids. About 6 hours per charge and roughly 30 hours total with the case.
• Best for fit and noise isolation → Dekoni Audio Bulletz TWS Memory. Slow-rebound foam seals the canal and reduces external bleed better than silicone.
• Best for kids, gifts and casual listening → AMAFACE Kids. The cartoon kitty case, touch controls and IPX5 rating fit that use case.
• Best for commuters and gym-goers → Dekoni Audio Bulletz TWS Memory. The secure, no-slip foam fit is exactly what workouts and noisy commutes reward.
• Best for call clarity and convenience → AMAFACE Kids. Built-in mic, touch volume control and automatic pairing out of the case.
• Best for compatibility with specific premium earbuds → Dekoni Audio Bulletz TWS Memory. Check your model against the listed Sennheiser, Sony, Beats, Jabra, Jaybird and Fostex options.
In my opinion, these two products barely compete — they solve different problems, and the right pick falls out of one question: do you already own earbuds? If yes, I would buy the Dekoni Audio Bulletz TWS Memory, because a proper foam seal is the cheapest real upgrade to comfort, bass and isolation on earbuds you already like. If you need the earbuds themselves — especially for a kid or as a gift — I would buy the AMAFACE Kids for its complete kit, long total battery life and playful design. If you are weighing cost, check the current price on Amazon before deciding, since the value math changes a lot between a tip upgrade and a full headphone set.
how to connect tws earbuds
For the AMAFACE Kids, simply take the earbuds out of the charging case — the data sheet says they pair automatically over Bluetooth once removed. Then select them in your phone's Bluetooth menu. Dekoni Bulletz are not electronic, so there is nothing to connect; they are physical ear tips you push onto your existing earbuds.
how to pair tws earbuds
Pairing is the same step as connecting: enable Bluetooth on your device, remove the AMAFACE earbuds from the case, and choose them from the available device list. The listed Bluetooth range is about 10 meters, so keep your phone close during setup. If pairing stalls, put the earbuds back in the case and start again.
how to reset tws earbuds
The data sheet does not list a reset procedure for the AMAFACE Kids, so the usual approach is to place both earbuds back in the charging case, let them power down, then remove them to re-initiate pairing. If that fails, your best move is to contact the brand, which states it is committed to customer service.
how to tws earbuds
If you mean getting the most out of a TWS setup: fit matters first. The AMAFACE Kids ship with three tip sizes (S, M, L), and Dekoni Bulletz come in Small 10.5mm, Medium 12.5mm and Large 13.4mm. A correct seal improves bass and isolation on either product, so experiment with sizes before judging the sound.
