Why Does My Vape Make Hissing Sounds After Use?

May 14 , 2025 · By Raz Vape Team

You take a draw, set your vape down—and suddenly it crackles like a campfire. It’s not exactly the peaceful puff you were going for. If you’ve ever wondered why your vape makes odd sounds after use, you’re not alone. While a little noise is normal, there are times it could point to something worth your attention.

Let’s break it down: what’s normal, what’s not, and how smart design—like that behind the RAZ LTX 25K—can help keep things quiet and safe.

1. What Sounds Are Actually Normal?

Vaping isn’t silent. When the coil heats up and turns e-liquid into vapor, it naturally makes a bit of noise:

• Hissing – This is the sound of the coil heating. It’s usually soft and short-lived.
• Crackling or popping – Often heard at the start of a puff, especially if there’s a bit more liquid in the chamber.
• Airflow – Devices with tighter airflow tend to be quieter. Mouth-to-lung models like the LTX 25K are typically more subtle.

As long as the sound happens while you’re using the vape and fades quickly after, there’s no reason for concern.

2. Why Is My Vape Still Making Noise After I’ve Stopped Using It?

Some sounds are fine. But if your vape keeps hissing after you’ve taken a puff, that’s worth paying attention to.

A. Persistent Hissing or Buzzing

A coil that continues heating after a puff could point to a battery issue or a stuck sensor. With disposables, don’t try to open the device—just cover the airflow hole to cut off activation.

Devices with built-in protections, like the LTX 25K, regulate coil temperature to reduce the chance of overheating or accidental firing.

B. Gurgling or Spitting

A gurgling noise means excess e-liquid has made its way into the airflow path. It might be caused by drawing too hard or leaving the device in a warm pocket. Either way, stop using it and clear it out before continuing.

C. No Sound, No Vapor

If your vape is completely unresponsive, the battery may be dead—or something inside is no longer working. In models with USB-C recharging (like the LTX 25K), a quick charge may solve the issue. If not, it’s time for a replacement.

3. Should I Be Worried About These Sounds?

In most cases, no. But if your device is making noise even when you’re not touching it, it could be a sign of internal pressure or battery venting.

If that happens:

1. Set the device on a non-flammable surface.
2. Keep it away from your face and don’t inhale any vapor or gas.
3. Block the airflow hole to disable the draw activation.

The LTX 25K helps you stay ahead of issues by displaying battery and e-liquid levels in real time, giving you more control and awareness.

4. Quick Fixes for Common Noises

Here are a few things to try before tossing a noisy vape:

• Flooded coil? Hold the device upright and gently tap or flick to clear excess liquid.
• Overheating? Let it cool for a few minutes—especially after long sessions.
• Battery low? Recharge if the model allows it (the LTX 25K does).

If issues keep coming back, it’s often easier (and safer) to switch to a new device. High-capacity options like the LTX 25K can last thousands of puffs, so replacements are infrequent.

5. What Makes the LTX 25K Quieter—and Smarter?

Not all disposables are built the same. The LTX 25K is designed with quiet, reliable use in mind:

• 16ml of pre-filled e-liquid ensures less chance of flooding or sputtering.
• Smart display tracks battery, puff count, and mode—so you’re never guessing.
• Dual modes give you control: Boost Mode for more vapor, Normal Mode for longer use.
• Temperature-regulated coil system prevents dry hits and minimizes risk of overheating.

It’s a solid choice for those who want consistent performance without the noise or hassle.

Final Thoughts

Vaping isn’t silent—but it shouldn’t be worrisome either. Understanding the difference between a normal crackle and a red flag gives you peace of mind. And choosing a well-designed device can go a long way in reducing issues altogether.

Whether you’re just starting out or have been vaping for years, a device like the LTX 25K makes it easier to enjoy the experience—minus the surprises.
