- Very affordable
- Comfortable open-ear design
- Stable Bluetooth connection
- Good battery life
- Weak bass and basic sound quality
- No noise isolation
- Average microphone
The Lenovo EA400 earbuds deliver comfort, simple controls and solid battery life at a super-low price. They fit securely without silicone tips and are great for casual listening or calls. However, the sound quality is basic and bass is weak, making them less appealing for music-focused users seeking strong audio performance.
The Lenovo EA400 is a budget-friendly pair of wireless earbuds with a trendy clip-style design — no silicone tips, no tight seal, just a lightweight fit that rests comfortably on your ears.
But how do they actually perform in everyday use?
I’ve been testing them for a few days, and in this review, I’m sharing my full experience and honest thoughts about these earbuds.

Design & Comfort
These are open-ear / clip style earbuds. There’s no silicone tip, so they don’t seal your ears. I personally like that style because my ears don’t get tired.
When I first put them on, they sat firmly and didn’t feel like they would fall off. I shook my head around a bit — still secure. Comfort is honestly the highlight of this model.
If you prefer hearing the environment around you while listening, you’ll probably enjoy this design.
Bluetooth & Controls
The EA400 uses Bluetooth 5.4, and pairing was quick. I took them out of the case, turned on Bluetooth on my phone, and they showed up right away.
Touch controls are included:
- Tap once → Play/pause or answer calls
- Double tap → Skip forward (right) or back (left)
- Hold for a moment → Voice assistant
- Triple tap → Reject calls
Nothing fancy, but it covers the basics well.
Sound Quality
Now the part I was most curious about: the sound.
The volume goes really loud. But the audio quality doesn’t keep up, especially with bass-heavy music. On lower volumes, it’s okay — casual listening, podcasts, YouTube all fine.
But when the bass kicks in:
- It loses quality
- Details disappear
- High volumes get harsh
So if you love music with deep bass… this isn’t for you.
Microphone Quality
When I switched my phone to the EA400 mic during a call, people said my voice sounded clear enough inside the house. It isn’t studio quality, but definitely usable.
Outdoors, background sounds become noticeable — but still better than some cheap TWS mics I’ve tried before.
Battery Life
Lenovo claims:
- Up to 5 hours per charge
- Up to 24 hours total with the case
From my usage:
▶ Music at ~60% volume lasted almost the full 5 hours
▶ Charging case topped them up several times easily
For this price, the battery performance is actually impressive.
And thanks to the LED indicators on the case, you always know how much power is left — something many cheap earbuds don’t include.
Who Are These For?
After using the Lenovo EA400 for a while, here’s my honest takeaway:
A very comfortable and affordable earbud that gets basic everyday tasks done — but not made for serious music lovers.
The Lenovo EA400 makes sense if you:
✅ Want extremely cheap wireless earbuds
✅ Prefer open-style designs with no ear tip pressure
✅ Need something mainly for podcasts, YouTube, or calls
✅ Care more about comfort than premium sound
You should avoid them if you:
❌ Want strong bass and immersive music
❌ Need noise isolation
❌ Plan to use them in noisy environments
