OneOdio A70 Review – The Truth About This “Bass Monster” Headphone

A few weeks ago, I found myself staring at yet another “best budget headphones” list online. You know the kind, big promises, huge bass claims, and photos of shiny earcups that look far fancier than the price suggests. One name kept popping up again and again: the OneOdio A70.

People called them “bass monsters,” “DJ-friendly,” “crazy battery life,” and even “the best under $50.”
But at the same time… the complaints were just as loud.
Some said the comfort was rough. Others said the treble was sharp. A few said you could basically hear your oven fan through them because the isolation was that bad.

And I thought, Okay, I need to test these myself.

If you’re here, chances are you’re wondering the same thing I wondered:
Are the OneOdio A70 actually worth buying, or are they just another overhyped budget headphone?

Stick with me, because I’m going to walk you through exactly what I experienced, everything I loved, everything that annoyed me, and the parts no one ever mentions… including insights from real users, hands-on testing.

By the end of this review, you’ll know whether the A70 fits your style, your ears, your budget, and your expectations, or if you should run the other way.

OneOdio A70 Headphones Review

View on Amazon

Let me introduce them properly.
The OneOdio A70 are marketed as versatile, DJ-friendly, hybrid headphones that can switch between wired and wireless mode seamlessly. OneOdio positions them as a go-to pair for bass lovers, hobby DJs, students, travelers, and anyone who wants long battery life without paying big money.

That’s the idea anyway.

In reality, they’re a mix of genuinely cool features… and some glaring issues.

Let’s break it down.

Design & Build Quality

At first touch, the A70 feel lighter than their 250 g weight suggests. The matte plastic looks refined, the accents are clean, and the rotating/folding hinges help them pack down easily.

But then you put them on.

And at least for me, and many reviewers, I immediately felt a pressure point right on top of my head.

Why?
The padding is straight and doesn’t contour to your head shape. All the weight sits in one spot. After 30–60 minutes, you really start to feel it.

On top of that, the faux leather pads trap heat. Within minutes my ears felt warm, and after an hour? Definitely sweaty.

Isolation is almost zero.
The lightweight plastic doesn’t block much sound at all. I could hear my oven fan across the room. If you’re planning to use these in a noisy place or on a commute… don’t.

But there is one thing I truly loved:

The dual-jack cable system (3.5mm + 6.3mm).

OneOdio absolutely nailed this.

You can:

• Plug into either jack depending on your device
• Lock the 3.5mm connector in place
• Even share audio using their “SharePort” feature (two wired headphones plugged into one source)

This is one of the genuinely innovative parts of the A70.

Battery Life & Bluetooth Performance

OneOdio claims 50 hours of battery life.
Some users say it even outperforms its advertised 72-hour spec (depending on region/model variations).

In my use, I hit 30+ hours without killing them, so the claim seems believable.

Bluetooth range is stable, I walked around my house without dropouts except at the very edge.

But there’s one weird thing no one warned me about:

Sometimes the first one second of your music gets cut off.

You tap play… and the track starts one second late.
It doesn’t happen every time, but it happens enough to mention.

Also:

• Only SBC and AAC codecs
• No aptX, no LDAC
• No ANC
• No Bluetooth standard listed by OneOdio

Pretty basic wireless functionality.

Soundstage & Imaging:

Better width than expected, almost no depth.
Instrument imaging is fuzzy.
Background hiss is audible at low volumes in Bluetooth mode.

In short:

These are NOT audiophile headphones.
These are FUN headphones.
And those two things are not the same.

Buy them if you:

• Love bass
• Want long battery life
• Need wired + wireless versatility
• Are on a budget
• Are a DJ or casual music lover

Avoid them if you:

• Want accurate, balanced sound
• Are sensitive to head pressure
• Need noise cancellation
• Expect premium durability

Pros

• Huge, fun, energetic bass
• Excellent battery life (30–50+ hours)
• Lightweight design
• Super versatile wired options
• SharePort audio-sharing system
• Stable Bluetooth connection
• Affordable price point

Cons

• Bass overwhelms mids
• Treble peaks and becomes fatiguing
• Comfort issues after 30–60 minutes
• Very poor noise isolation
• Background hiss in Bluetooth mode
• Outdated micro-USB charging
• Not suitable for mixing, monitoring, or critical listening

Quick Picks

If you need a fast answer, here it is:

Best Overall (For Bass Lovers):

➡ OneOdio A70

Not for everyone, but if you love a fun, heavy low end and long battery life at a low price, this is your pair.

Best Budget Pick (If You Want Balanced Sound)

➡ Consider alternatives like the Anker Soundcore Life Q30 (if available on sale)

More comfortable, more balanced, better features.

Best Premium Pick

➡ Sony WH-CH720N or Audio-Technica M40x (wired)

Better sound, better comfort, more accuracy.

FAQs

1. Are the OneOdio A70 good for mixing or studio use?

No. The tuning is far too bass-heavy and the mids are too recessed. They can mislead your mixes.

2. Do the A70 have noise cancellation?

No. Isolation is very weak due to thin materials and minimal clamp force.

3. Can you use them wired without battery?

Yes. Wired mode works even when the battery is dead.

4. Are they good for the gym?

Only if you love bass. But they get hot quickly and aren’t very secure on the head.

5. How long does the battery last?

Real-world: 30–50 hours depending on volume.
Some users have reported even more.

Final Summary

Here’s the honest, balanced verdict.

The OneOdio A70 is a fun, affordable, bass-forward pair of hybrid headphones that works extremely well for certain types of listeners, and extremely poorly for others.

You should buy them if you want:

• Explosive bass
• Long battery life
• Multiple wired + wireless options
• A low price
• DJ-friendly features like SharePort

But you should skip them if you value:

• Comfort
• Detail
• Balanced sound
• Isolation
• Modern charging or codecs
