Cleer Audio Unveils Arc 4 Series: World’s First THX Certified Open-Ear Wireless Earbuds

Experience next-level open-ear sound with Cleer Audio’s Arc 4 series, featuring THX certification and immersive Dolby Audio technology.

A New Era of Open-Ear Audio Begins

Let’s talk about headphones that don’t just sit in your ears but redefine what open-ear listening means. When I first heard about Cleer Audio’s latest drop—the Arc 4 and Arc 4+—I couldn’t help but get excited. These earbuds aren’t just another wireless option; they’re the world’s first THX® certified open-ear true wireless earbuds. That’s a mouthful, but it basically means Cleer is pushing the limits on sound quality and comfort for open-ear tech, and they’re doing it with some serious audio cred.

Cleer Audio’s sleek Arc 4 Series earbuds set a new standard for open-ear listening

Next-Level Design Meets Comfort

If you’re like me, you want your earbuds to feel almost like they’re not there, while still delivering killer sound. The Arc 4 Series nails this by being 10% lighter than the previous model, with ear hooks trimmed down by 45%. The result? A snug, ergonomic fit that hugs your ear canal just right. The difference is noticeable—music sounds clearer, more precise, and you barely feel the buds during those long listening sessions.

• Arc 4 Price: $99.99
• Arc 4+ Price: $129.99

Setting a High Bar: THX® Certification

Here’s where Cleer really steps into the spotlight. The Arc 4 Series carries the prestigious THX® Headphone Certification, a badge that ensures sound accuracy and minimal distortion in an open-ear design—a tricky feat given the natural ambient noise around you.

THX certification means these earbuds offer:

• Balanced frequency response
• Crystal-clear vocals and detailed highs
• Punchy but controlled bass
• Precise left/right channel matching for an authentic soundstage

What’s wild is how these earbuds maintain clarity, even when pumped up loud, without that harsh distortion you sometimes get in wireless buds. Tuned by THX engineers, they follow the THX optimal frequency response curve, delivering sound that’s true to the original recording.

Dolby Audio and Atmos: Dive Into Immersive Sound

If you thought that was impressive, wait till you hear about the Arc 4+’s Dolby Atmos® capabilities. The Arc 4 offers Dolby Audio for crystal-clear stereo and multichannel sound, but the Arc 4+ takes it a step further with:

• Dolby Atmos® optimization for 3D object-based audio
• Dolby Sensor-built head tracking that locks the soundstage even as you move your head

This means you’re not just hearing music—you’re inside it. The spatial audio reacts dynamically, creating an immersive experience whether you're watching a movie or listening to your favorite album.

Hi-Res Audio and Wireless Tech That Impresses

Cleer doesn’t stop at sound quality—they’ve packed the Arc 4 Series with features audiophiles and casual listeners alike will appreciate:

• Hi-Res Audio support with a frequency range from 65Hz to 40kHz
• Dynamic Bass Enhancement (DBE 4.0) for punchier, deeper bass
• Bluetooth® 5.4 for stable wireless connectivity
• Snapdragon® Sound technology for ultra-clear, lag-free audio
• Multipoint support allowing easy switching between devices
• Qualcomm® cVc microphones to cut down on background noise and echoes

These earbuds also support aptX Lossless and voice control, elevating wireless listening to a level where detail and clarity really shine.

Designed for Life on the Go

One of the best parts about the Arc 4 Series is their lightweight design—each earbud weighs just 10.8 grams and they fit so comfortably, it’s like they vanish. The charging case has been slimmed down for easy pocket carry, yet it’s robust enough to protect and keep your buds powered.

• Slimmer, pocket-friendly charging case
• IPX7 water resistance to tackle sweat and rain
• Up to 32 hours of playback on the Arc 4 (7–9 hours per charge plus 25 hours from the case)
• Up to 34 hours of playback on the Arc 4+

The Arc 4+ also boasts additional perks like physical on/off controls, Apple MFi certification for seamless iOS compatibility, and Dolby Head Tracking for that next-level immersive feel.

Your Sound, Your Way with the Cleer+ App

Customization is king, and the Cleer+ app gives you the throne. From customizable EQ settings to touch control mapping and battery monitoring, it’s all about making these earbuds your own.

Plus, the Arc 4+ offers a distinctive pink finish alongside classic black and white options—because why not blend high-tech with personal style?
