• AZLA SednaEarfit Crystal — biggest strength: hypoallergenic German LSR silicone with a naturally grippy surface, so your existing earbuds stay put and seal better without altering the original tuning.
• AZLA SednaEarfit Crystal — biggest trade-off: it is a set of replacement tips, not a pair of earbuds. You need to already own compatible buds, and it will not fit models with a long or wide nozzle.
• Xmenha Earbuds True — biggest strength: a touchscreen charging case, Bluetooth 5.4 with a claimed 15ms low-latency path, app-based EQ and motion controls, and IPX5 sweat resistance.
• Xmenha Earbuds True — biggest trade-off: playtime is listed at 6 hours per charge in either mode, and the case is plastic. The screen is the headline feature, so you are paying for that design idea.
• Who each pick is for: AZLA for the tinkerer who loves their current buds but fights slippage and weak isolation; Xmenha for the gamer or gym-goer who wants one self-contained kit with a gadget-forward case.
The SednaEarfit Crystal is a replacement eartip, and everything about it is designed around that single job. The material is German LSR silicone, described as hypoallergenic and gentle on sensitive ears, with a surface that stays naturally grippy instead of slick. That combination matters more than it sounds. If you have ever had a bud work its way loose halfway through a run, or felt a raw ache after two hours of listening, the tip is usually the culprit, not the driver.
Fit is the other half of the story. AZLA offers multiple sizes in a short 4mm core length, sized from a study of ear shapes, and the short core is deliberate: it is meant to sit deep enough to seal without pushing the bud out of its charging case. The company lists compatibility with Beats Powerbeats Pro and Powerbeats Pro 2, plus Galaxy Buds 2, Buds and Buds+, and says the tips fit a wide range of TWS Bluetooth earbuds generally. Just as important is the exclusion list — Galaxy Buds Pro, Galaxy Buds Live and AirPods Pro are explicitly not supported, so check your model before ordering.
Who should buy it? Someone who already likes the sound of their earbuds and only wants better grip, better passive isolation and more comfort. The acoustic seal is the mechanism here: a tighter seal blocks more outside noise and firms up bass, and AZLA frames the design as preserving your earbuds' original sound signature rather than reshaping it. Who should skip it? Anyone shopping for their first wireless earbuds, and anyone whose buds are on the incompatible list. In my opinion this is a maintenance-and-upgrade purchase, not a starter purchase.
The Xmenha Earbuds True is a full true wireless system built around one very visible idea: the charging case has a built-in HD touchscreen. It shows battery status and playtime, and it doubles as a small interface for game selection and personalization, including DIY wallpaper. That is the feature you either find genuinely useful or completely unnecessary, and it defines the whole product.
Underneath the screen, the spec sheet is aimed squarely at gaming and workouts. Bluetooth 5.4 handles connectivity, with a stated 15ms low-latency transmission path and a 45ms Gaming Mode; there is also a Hi-Fi Music Mode, and both modes are listed at 6 hours of playtime. Dual-mic ENC handles calls, an app adds motion-sensing game sensitivity, GPS route tracking and AI-driven EQ customization, and the IPX5 rating covers sweat during training. The 10-ohm balanced armature driver covers 20 Hz to 20,000 Hz.
Who should buy it? Mobile gamers who notice audio lag, gym-goers who want one pair of buds for both training and entertainment, and anyone who enjoys a case that does more than hold a charge. Pairing is automatic across iOS, Android and Wear OS, with Siri and Google Assistant support. Who should skip it? Listeners who want the longest possible single-charge runtime, and anyone who prefers a plain, pocketable case. The screen is the reason to buy this; if it leaves you cold, the rest of the package is conventional.
• Best for improving earbuds you already own → AZLA SednaEarfit Crystal. It is the only one of the two that upgrades a product you have rather than replacing it.
• Best for a complete out-of-the-box solution → Xmenha Earbuds True. Buds, case, app and controls all arrive in one package.
• Best for gaming latency → Xmenha Earbuds True. Bluetooth 5.4 with a stated 15ms low-latency path and a 45ms Gaming Mode is the spec that matters here.
• Best for workouts and sweat → both, for different reasons. AZLA's grippy LSR surface keeps your existing buds locked in; Xmenha's IPX5 rating protects the electronics themselves.
• Best for sensitive ears and long sessions → AZLA SednaEarfit Crystal. Hypoallergenic silicone is the whole point of the material choice.
• Best for battery expectations → Xmenha Earbuds True, at 6 hours per charge in either mode, though that is not class-leading. AZLA has no battery at all, because it has no electronics.
• Best for phone-free convenience → Xmenha Earbuds True. The touchscreen case shows status and settings without opening your phone.
• Best for fit flexibility → AZLA SednaEarfit Crystal, thanks to multiple sizes and a 4mm short core that keeps case compatibility intact.
I would buy the AZLA SednaEarfit Crystal if I already owned a compatible pair of earbuds I liked. It solves the two problems that actually make people give up on good buds — slippage and a weak seal — with a material choice that is genuinely thought through, and it does it without touching the sound signature. I would buy the Xmenha Earbuds True if I were starting from nothing and wanted a gaming-first kit where the case itself is part of the fun. If I had to pick one for most people, I would pick Xmenha, simply because it works on day one with no compatibility homework. Check the current price on Amazon for both before you decide.
how to connect tws headphones
Put the earbuds in the case, open the lid, and let them enter pairing mode — usually indicated by a flashing light. Then open your phone's Bluetooth settings and select the earbuds from the list. The Xmenha Earbuds True is listed as pairing automatically with iOS, Android and Wear OS systems, which skips most of that manual step.
how to pair tws headphones
Pairing means making the two buds talk to each other before they talk to your phone. Most true wireless sets do this automatically once both buds leave the case at the same time. If they do not, the usual fix is to return both to the case, close it, and start again with a clean slate.
how to use tws headphones
Charge the case, take the buds out, and connect once over Bluetooth. After that, playback and volume are handled by touch controls on the buds — the Xmenha Earbuds True uses touch for volume and playback, and its app adds EQ and motion-sensitivity adjustments. AZLA SednaEarfit Crystal tips are not electronics, so there is nothing to operate; you fit them and go.
how to reset tws headphones
A reset clears old pairings and fixes one-bud-only audio or failed connections. The common method is to place both buds in the case, forget the device in your phone's Bluetooth menu, then hold the case button or touch both buds until the lights flash. Because reset routines differ by model, follow the manufacturer's instructions for your specific earbuds.
