If you want replaceable silicone tips that can improve the fit and passive isolation of compatible earbuds for calls, choose AZLA SednaEarfit MAX; if you need complete wireless earbuds with call-focused microphone noise reduction, choose Ttbesmi TWS-19. For calls, the key difference is simple: AZLA is an accessory for earbuds you already own, while Ttbesmi is a standalone Bluetooth earbud set.
I’d choose based on what you need to change. AZLA may help compatible earbuds sit more securely and maintain a sealed fit; Ttbesmi includes its own Bluetooth 5.3 connection and dual-microphone ENC. Neither is an over-ear headset, so searches for “rotatable ear cups on ear headphones for calls” or “noise canceling gaming headphones for calls” point to a different kind of product.
• AZLA SednaEarfit MAX strength: Medical silicone tips designed for comfort, a stable seal, and passive noise isolation. Trade-off: They are replacement tips, not earbuds; compatibility depends on your earbud model and nozzle.
• Ttbesmi TWS-19 strength: Complete wireless earbuds with Bluetooth 5.3 and dual-microphone ENC intended to reduce environmental noise during calls. Trade-off: The listed continuous playtime is five hours, and the in-ear shape may not suit everyone.
• Choose AZLA if you already own compatible earbuds and want to focus on fit, comfort, or isolation.
• Choose Ttbesmi if you need a complete wireless set with call controls and the option to use one or both earbuds.
AZLA SednaEarfit MAX is a replacement-tip option for people who already have compatible wireless earbuds. Its soft matte medical silicone and tapered shape are designed to create a comfortable, stable seal. That can matter on calls: a tip that stays seated can help keep the earbuds in place as you move, while the seal is intended to improve passive isolation. These are design aims, not a guarantee of a particular call result.
The fit is the main reason to consider AZLA. The tips are offered in multiple sizes, and the stated compatibility spans a range of models, including certain Beats, Galaxy Buds, AirPods Pro, Jabra, JBL, Sony, and other earbuds. Check the exact earbud model and fit before choosing; compatibility is not universal. The tips are not a microphone, Bluetooth device, or standalone pair of headphones.
I’d consider AZLA if your current earbuds work well but their tips feel uncomfortable, fail to stay put, or do not seal as you want. The product information also says it is designed to preserve the earbuds’ original sound signature. Skip it if you need a complete set of wireless earbuds, call microphones, or a new Bluetooth connection. AZLA changes the earbud tip, not the core electronics.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Ttbesmi TWS-19 is a complete pair of in-ear Bluetooth earbuds, rather than an accessory for another set. Bluetooth 5.3 handles the wireless connection, and the listed range is 10 meters. For calls, its most relevant feature is ENC with dual microphones and AI voice recognition, described as reducing environmental noise. That makes it the more direct choice for someone seeking call-oriented earbuds, though the specifications do not establish how well it performs in every noisy setting.
The earbuds can be used one at a time or as a pair, and the controls include answering and ending calls. The listed continuous playtime is five hours, with an additional 30 hours described as available from the charging case. The earbuds take one hour to charge, and the case uses a Type-C charging port. This gives the TWS-19 a self-contained setup that AZLA cannot provide.
Its stated fit is an ergonomic, half-ear in-ear design, with a U-shaped structure described as suited to smaller ear canals. It is also listed as suitable for children aged six and older, and as resistant to sweat and rain. I’d consider it for someone who wants a complete, lightweight-feeling set for everyday calls and listening. Skip it if your priority is improving the fit of earbuds you already own, or if five hours of continuous earbud playback does not meet your routine.
• Best for replacing uncomfortable tips on compatible earbuds → AZLA SednaEarfit MAX. Its purpose is to change the fit, seal, and contact material of earbuds you already own.
• Best for a complete wireless setup → Ttbesmi TWS-19. It includes Bluetooth 5.3 earbuds, touch controls, and a charging case.
• Best for call-focused microphone features → Ttbesmi TWS-19. Its dual-microphone ENC is specifically described as helping with environmental noise during calls.
• Best for passive isolation through a sealed fit → AZLA SednaEarfit MAX. Its tapered silicone tips are intended to create a stable acoustic seal; they do not add electronic noise cancellation.
• Best if you want to use a single earbud → Ttbesmi TWS-19. The listed master/slave switching allows use of one earbud or both.
• Best if you already own earbuds you like → AZLA SednaEarfit MAX. It may address a fit issue without replacing the earbuds, provided your model is compatible.
• Best for an in-ear design described for smaller ear canals → Ttbesmi TWS-19. Its stated U-shaped structure is intended to suit that fit, but comfort remains personal.
• Best for longer listening between earbud charging sessions → Ttbesmi TWS-19, with a caveat. It lists five hours of continuous playback and additional power from the case; AZLA tips have no battery because they are not electronic earbuds.
For people searching for the best open ear headphones for calls, neither product is an open-ear headset: AZLA is a silicone tip, and Ttbesmi is an in-ear earbud. Likewise, neither has rotatable ear cups, and neither is an over-ear gaming headset with noise-canceling hardware. Those phrases describe a different form factor, so I would not choose either product expecting those features.
The call decision comes down to where the problem lies. If your existing earbuds’ fit is the weak point, AZLA is the relevant option. If you need earbuds with their own microphones and call controls, Ttbesmi is the more complete package. If you need both a new set and a different tip fit, these products are not direct substitutes; AZLA’s usefulness depends on compatible earbuds already being part of your setup.
In my opinion, I’d choose Ttbesmi TWS-19 for calls because it is a complete wireless set with dual-microphone ENC, call controls, and single-ear use.
I’d choose AZLA SednaEarfit MAX instead if I already owned compatible earbuds and the main problem was comfort, stability, or the seal.
For someone shopping specifically for calls, Ttbesmi is the more straightforward starting point; AZLA is a targeted fit upgrade, not a headset replacement.
No. They are replacement silicone tips for compatible earbuds, not a complete pair of earbuds. They do not provide Bluetooth, microphones, or call controls.
Ttbesmi is the more direct call option because it includes earbuds, dual-microphone ENC, and controls for answering and ending calls. AZLA may help with fit and passive isolation, but it relies on compatible earbuds for microphones and connectivity.
The tapered tips are designed to form a seal that can improve passive noise isolation. They are not described as electronic noise-canceling earbuds, though the seal may help compatible earbuds’ active noise cancellation work as intended.
The listed continuous playback time is five hours. The product description says the charging case provides an additional 30 hours, and lists a one-hour charging time for the earbuds.
