2 Lazy Audio Guide / The Details
Good sound is more than a number.
Headphones & earbuds: understand noise control, battery life, Bluetooth and app features before you choose.
Explore the guide ↘01 / Your priorities
What matters to you?
The best specification depends on where you listen. Start with your day before comparing numbers.
ON THE MOVE
Commute & travel
Look at noise control, comfortable fit and usable battery life.
AT YOUR DESK
Work & calls
Focus on microphone performance, connection options and long-wear comfort.
OUT & ABOUT
Movement & outdoors
Consider secure fit, awareness of your surroundings and stated water resistance.
EVERY DAY
Easy listening
Balance sound, convenient charging and controls you will actually use.
02 / Noise & clarity
What does “noise control” mean?
These terms describe different parts of the listening or calling experience.
THE FIT
Passive isolation
A physical seal or covering helps block some outside sound.
WHAT YOU HEAR
Active noise cancelling
ANC electronically reduces some external noise. Results vary by sound, fit and product.
WHAT THEY HEAR
Call noise reduction
Helps the other person hear your voice more clearly. It is separate from listening ANC.
THE MEASUREMENT
Signal-to-noise ratio
SNR compares a signal with background noise in a stated measurement. It is not a universal ANC score.
Takeaway: Choose noise control for your environment, rather than the largest dB figure alone.
03 / Battery
Read the hours before the mAh.
“Total playtime” and “one charge” answer different questions.
EARBUDS / ONE CHARGE
Time between case charges
How long the earbuds play before they need to go back into the charging case.
EARBUDS / WITH THE CASE
Total claimed playtime
Listening time after additional charges from the case, not one continuous session.
HEADPHONES
Playback per charge
Claimed listening time from the headphone’s own battery.
Battery capacity in mAh is not a fair standalone comparison between different designs. Volume, ANC and audio settings can change real-world playtime.

04 / Connection
A version number isn’t the whole connection.
A newer Bluetooth version alone does not guarantee better sound. Check the features supported by both your headphones and your phone or computer.
- Audio supportCodecs and features need compatible devices at both ends.
- Device switchingMultipoint can make moving between a phone and computer easier, where supported.
- Special modesLow-latency modes and LE Audio require support from the specific product and connected device.
05 / App features
Make the sound yours.
On compatible models, a companion app can give you more control after you buy.
TUNE IT
EQ controls
Adjust bass, mids and treble, or choose a preset where supported.
SET IT UP
Personal controls
Some models let you change gestures, buttons or listening modes.
KEEP IT CURRENT
Firmware updates
A compatible app may let you check and install available device updates.
Baseus offers companion-app features on selected models. App features and update options vary by model. Check the individual product page for supported functions.

07 / Quick answers
Still deciding?
Is ANC the same as call noise reduction?
No. ANC aims to reduce outside noise for the wearer. Call noise reduction aims to make your voice clearer to the person on the other end.
Why are earbud battery figures different?
One figure may describe playback on a single charge; a larger total may include extra charges from the case. Check the stated test conditions, especially whether ANC was enabled.
Does a newer Bluetooth version always sound better?
No. Sound also depends on the headphones, tuning, audio format and connected device. Check features rather than relying on the version number alone.
Do I need an app to use my headphones?
Many wireless headphones can play audio through a standard Bluetooth connection without an app. An app may be needed for particular settings or updates; check the product instructions.
Can I compare mAh between earbuds and headphones?
Not as a standalone measure of listening time. Designs and power use differ. Compare clearly labelled playback hours under similar stated conditions instead.
