Quick Answer
If the bass sounds distorted while exercising, adjust the fit of your H1E earbuds or try a different ear-tip size. Movement and sweat can affect the earbud seal, changing how the bass sounds.
Symptoms
Follow these steps if:
- Bass sounds distorted during exercise.
- Audio changes while running or moving.
- Bass becomes weaker or less consistent during a workout.
How to Improve the Fit and Sound
1. Try a Different Ear-Tip Size
Replace the current ear tips with another available size. The best size should feel comfortable while creating a secure seal in each ear.
You may need a different ear-tip size for each ear.
2. Reinsert the Earbuds
- Remove both earbuds.
- Reinsert each earbud carefully.
- Adjust them until they create a secure and comfortable seal.
- Play music and check the bass response.
3. Test the Fit Before Exercising
- Make sure each earbud fits snugly.
- Gently move your head to test whether the earbuds remain secure.
- Start your workout and check whether the sound remains consistent.
Result: With a secure seal, the bass should sound more consistent while you move.
Why Fit Affects Bass
Movement and sweat can loosen the seal between the ear tips and your ears. When the seal changes, the bass may sound weaker, uneven, or distorted.
A different ear-tip size can often improve:
- Fit and stability
- Comfort
- Bass response
- Overall sound quality
Frequently Asked Questions
Why does the bass change when I run?
Running and other movements can shift the earbuds and break their seal. Reinsert the earbuds or try another ear-tip size.
Should I use the same ear-tip size in both ears?
Not necessarily. If your ears require different sizes to create a comfortable, secure seal, you can use a different size on each earbud.
What if the bass is distorted when I am not exercising?
Test another app and connected device. If the distortion continues while stationary, contact Heavys Support and explain when it occurs.
