• Dekoni Audio Bulletz TWS Memory — biggest strength: Slow-rebound memory foam that expands to your ear shape, sealing the canal for better passive noise isolation and stronger bass, with a low-profile shape that still fits inside most true wireless charging cases.
• Dekoni Audio Bulletz TWS Memory — biggest trade-off: It is not an earbud. You need an existing pair of in-ears with a 4.9mm bore to put them on, and there is no electronics, no battery, no noise cancellation of its own.
• Xmenha lx300 — biggest strength: A complete Bluetooth 5.4 TWS package with active noise cancellation, a transparency mode, a touchscreen charging case you can control without your phone, and a rated 5–7 hours of play time per charge.
• Xmenha lx300 — biggest trade-off: It is a budget-built plastic earbud system, so the long-term durability and fit refinement are not on the same level as premium brands, and the fit relies on silicone tips that some ears simply do not get along with.
• Who each pick is for: Buy the Dekoni tips if you already like your current earbuds but hate how they fit; buy the Xmenha lx300 if you want a whole new set of cheap TWS earbuds with ANC and a screen on the case.
The Dekoni Audio Bulletz TWS Memory is a single-purpose product done properly. It is a pair of memory foam earbud tips, available in Small (10.5mm), Medium (12.5mm) and Large (13.4mm), with a universal 4.9mm bore that attaches to a wide range of in-ear models. Dekoni lists compatibility with Beats Powerbeats Pro, Jabra, Jaybird, Sennheiser Momentum and Sony WF-1000XM4, among others. The whole point is that the foam slowly rebounds and expands to fill your ear canal, which is exactly what silicone tips often fail to do.
That slow-rebound design matters more than it sounds. Silicone tips press back against your ear with constant force, which is why your ears ache after a couple of hours. Memory foam pushes outward gently and then stays put, so pressure stays low while the seal stays tight. A tighter seal means less outside noise leaking in and more bass energy staying in your ear, which is why foam tips are such a common upgrade for people who feel their earbuds sound thin. Dekoni also says these hold their shape instead of flaking apart, and that you can rinse them with cold water and gentle soap to keep them hygienic — a real advantage over disposable foam.
Who should buy it? Anyone who already owns true wireless earbuds they otherwise like but find uncomfortable, loose during workouts, or weak on bass and isolation. The low-profile silhouette is designed not to interfere with the charging case, so you are not fighting your case every time you put the buds away. The 3-pack option is sensible if you want a spare set. Who should skip it? Anyone who does not own in-ear earbuds yet, and anyone whose earbuds use a nozzle that is not around 4.9mm. Also note Dekoni lists no warranty on this item, so treat it as a consumable you will eventually replace.
The Xmenha lx300 is the opposite kind of product: a self-contained pair of cheap TWS earbuds. It runs Bluetooth 5.4 with a rated range of about 10 meters, uses a dynamic driver covering 20–20,000 Hz, and offers both active noise cancellation and a transparency mode. The headline feature is the touchscreen charging case — you can adjust sound modes, control volume, check battery levels for both the earbuds and the case, see the time and even set alarms from the case screen without pulling out your phone. That is an unusual amount of control for this price bracket.
On battery, the numbers split in a way worth reading carefully. Xmenha advertises 5–7 hours of play time and separately lists a battery average life of 6 hours, with a 400mAh battery and USB-C charging. The product description also mentions about 30 hours of total play time, which would include recharges from the case. Either way, 5–7 hours per charge is respectable for budget ANC earbuds and enough for a workday commute plus a gym session.
Side-by-Side: Which Should You Choose?
• Best for fixing earbuds you already own → Dekoni Audio Bulletz TWS Memory. If your current buds fit badly or sound thin, foam tips are the cheapest meaningful upgrade you can make.
• Best for a complete, no-extra-parts solution → Xmenha lx300. It arrives as a working pair of earbuds with a case, cable and manual — nothing else required.
• Best for active noise cancellation → Xmenha lx300. The Dekoni tips only isolate passively; the lx300 adds active noise cancellation plus a transparency mode.
• Best for comfort over long listening sessions → Dekoni Audio Bulletz TWS Memory. Slow-rebound foam reduces in-ear pressure in a way silicone cannot match over several hours.
• Best for workouts and sweat → Xmenha lx300, thanks to its sweatproof rating, though the Dekoni foam also grips well and resists slipping during movement.
• Best for battery life → Xmenha lx300. The Dekoni tips have no battery at all; the lx300 is rated 5–7 hours per charge with a 400mAh case battery.
• Best for travel and commuting → either, depending on your starting point. Have good buds already? Dekoni. Starting from nothing? Xmenha.
• Best for people with small ear canals → Xmenha lx300, which is explicitly designed around small ears, though the Dekoni Small size at 10.5mm is the fix if your issue is tip size rather than the earbud itself.
If I had to pick one, I would buy the Dekoni Audio Bulletz TWS Memory — but only because of the assumption that most people reading a cheap TWS comparison already own a pair of earbuds and are unhappy with the fit. In my opinion, a properly sealing foam tip changes how earbuds sound and feel more than most budget upgrades do, and the three-size range plus the 4.9mm universal bore make it easy to get right. That said, if you do not own true wireless earbuds yet, or you specifically want active noise cancellation and a touchscreen case, the Xmenha lx300 is the more complete purchase and the one I would recommend for a first-time buyer. Check the current price on Amazon for whichever one fits your situation.

TWS stands for "true wireless stereo" — earbuds that connect to your device over Bluetooth with no wire between the left and right bud. The Xmenha lx300 is a full TWS product; the Dekoni Bulletz TWS Memory is a set of replacement foam tips made for TWS earbuds.

It simply means the two earbuds are independent and pair wirelessly to each other and to your phone. That is why the lx300 has its own battery, Bluetooth 5.4 radio and charging case, while the Dekoni tips are just the foam part that goes on the nozzle of an earbud you already own.
