Cleer Audio is making a clear statement with ARC 5 by packing in a lot of technology into an earbud.

Open-ear earbuds have traditionally been about convenience: situational awareness, comfort, and fitness-friendly design. Sound quality? That’s usually been the compromise. But with the ARC 5, Cleer is clearly trying to change that narrative—and the company’s THX partnership is the clearest signal yet that it’s taking sound seriously.

This is one of the most ambitious pushes we’ve seen in the category, and frankly, it’s overdue.

 

Why the ARC 5 Matters

At a glance, the ARC 5 looks like a refinement of the ARC 3. But under the hood, this is a meaningful step forward.

You’re getting:

• THX® Headphone Certification

• THX® Spatial Audio with head tracking

• Dolby Atmos optimization

• Qualcomm Snapdragon Sound (S5 Gen 3) with aptX Lossless

• A redesigned, lighter open-ear form factor

• A genuinely useful AMOLED touchscreen smart case

That’s a lot of tech for a category that’s often treated as “good enough.” And that’s exactly why this product matters. Cleer is trying to elevate open-ear audio from a niche utility into something closer to a premium listening experience.

 

THX Certification: What It Actually Means

Let’s address the headline feature. THX Certification and the validation process.

When a headphone is THX-certified, it has gone through testing for:

• Frequency response accuracy

• Low distortion levels

• Channel consistency and imaging

• Noise performance and overall tonal balance

In simple terms, it means the ARC 5 is tuned to meet a reference-level standard and sound.

For end users, that translates to:

• More accurate, natural vocals

• Better instrument separation

• Less harshness at higher volumes

• A more consistent listening experience across content

Pair that with THX Spatial Audio, and you’re getting something even more interesting.

 

Spatial Audio That Actually Tries to Be Accurate

Spatial audio is everywhere right now, but not all implementations are equal.

Cleer’s approach combines:

• THX Spatial Audio

• Head tracking

• Dolby Atmos optimization

That combination matters. Instead of just widening the soundstage artificially, the ARC 5 attempts to anchor audio in space, adjusting based on head movement. That’s closer to how we actually hear sound in real life. And crucially, it does this while maintaining the open-ear design, so you’re still aware of your surroundings.

 

Hardware Upgrades That Actually Matter

Cleer didn’t stop at audio processing. The ARC 5 also improves the fundamentals:

Design & Comfort

• 11.5g per earbud (lighter than ARC 3)

• Thinner ear hooks for reduced pressure

• Improved acoustic positioning

These are subtle changes, but they matter for long listening sessions.

Smart Case That’s Actually Smart

The AMOLED touchscreen case isn’t just a gimmick:

• Playback control

• EQ adjustments

• Battery monitoring

• UV-C sterilization

Compared to the ARC 3’s LCD case, this feels like a real upgrade.

Battery & Durability

• Up to 60 hours total battery life

• 12 hours per charge

• 5-minute quick charge = ~2 hours playback

• IPX7 waterproofing

That’s competitive, even outside the open-ear category.

The Snapdragon Sound Advantage

The jump to Qualcomm S5 Gen 3 is another quiet but important upgrade.

This enables:

• aptX Lossless audio

• Lower latency

• Better connection stability

• Improved power efficiency

In real-world use, that means:

• Cleaner wireless audio

• Fewer dropouts

• Better performance across devices

It’s one of those quality-of-life upgrades you don’t notice immediately, but you feel over time.

 

Cleer Is Playing the Long Game

Cleer is clearly positioning itself as a serious audio brand, not just another lifestyle headphone company. And the THX partnership reinforces that.

As CEO Hideaki Yamaguchi (Yama) puts it:

“ARC 5 represents a major leap forward in open-ear audio. By combining THX® Certification and THX® Spatial Audio with improved ergonomic design… we’ve created earbuds that deliver immersive cinematic audio, unmatched comfort, and exceptional value.”

 

Why This Is a Big Deal for the Category

Open-ear audio has always been about compromise.

You trade:

• Isolation → awareness

• Bass → comfort

• Fidelity → convenience

The ARC 5 narrows the gap more than most products in this space.

 

Final Take

At $219.99, the ARC 5 sits in an interesting position. It’s not cheap, but it’s also not trying to be a flagship killer.

Instead, it’s doing something smarter:

• Elevating a category that’s been underserved

• Bringing real audio credibility (THX) into open-ear design

• Delivering meaningful upgrades over its predecessor

And most importantly, it signals that Cleer isn’t content to sit still. This is a company pushing forward and if the ARC 5 is any indication, the rest of the industry may need to catch up.
