Open-ear headphones which don’t go into the ear canal but instead clip onto the ear are no longer a niche product, and Soundpeats is making a strong splash in the entry-level segment with the UU2 (also marketed internationally as the Pop Clip2). For under 70 euros, you get Bluetooth 6.0, LDAC support, physical control buttons instead of unreliable touch panels, and a battery life of up to 42 hours, including the charging case. The successor to the Soundpeats Clip1 is designed to improve primarily in sound quality and comfort. Our review reveals who the Soundpeats UU2 is best suited for and where the trade-offs lie with its affordable entry-level price.

Soundpeats UU2 Review: Design and Build Quality
Like its predecessor, the UU2 features an open-ear design: Instead of an earbud that fits inside the ear canal, the speaker sits outside the ear, while a flexible memory-wire hook made of highly elastic TPU and a nickel-titanium alloy secures the earbud to the earlobe. The advantage of this design: no pressure in the ear canal, no “vacuum” effect, and the ability to hear ambient sounds at all times.
Ideal for running, cycling, or the office, where you still want to be able to hear people speaking to you. This design is already familiar from the premium Huawei FreeClip 2 S (review) or the QCY Crossky C50 (review). Weighing about 4.7 to 5 grams per earbud, the UU2 is among the lighter models in its class and is noticeably lighter than many closed-ear true wireless models. I particularly like how comfortable they are to wear.
The “skin-friendly surface” causes no irritation even after hours of wear, and the ear hook is thinner than on many competing models yet remains stable and can be adjusted to fit individually. Visually, the UU2 looks more sophisticated and understated than its predecessor, the Clip1. No flashy gaming design—just a subtle, everyday-friendly look in black.
Features: Drivers, Bluetooth, and Codecs
Inside each earbud, Soundpeats has installed a 12-mm dual-magnet driver. This dual-magnet design is intended to provide more powerful drive to the diaphragm, which is said to be particularly noticeable in bass reproduction—more on that in the sound section.
When it comes to wireless connectivity, the Soundpeats UU2 is state-of-the-art: Bluetooth 6.0 promises a more stable connection and lower latency compared to older standards, with a range of up to 15 meters. In terms of codecs, the earbuds support LDA in addition to the standard SBC and AAC codecs. LDA is a high-resolution codec typically found in higher-priced models, which enables a higher transmission bandwidth and potentially better sound quality for compatible Android devices.
However, if you actively use LDAC, you should expect a slightly shorter battery life of about 7 to 8 hours instead of the full 10 hours. The connectivity features are rounded out by Multipoint, which allows the UU2 to pair with two devices simultaneously—handy for switching back and forth between a laptop and a smartphone without having to reconnect each time.
Controls: Physical Buttons Instead of Touch
Instead of the touch panels commonly found on open-ear models, Soundpeats has opted for physical buttons on the UU2. This may seem old-fashioned at first glance, but in practice it offers a tangible advantage: The controls work reliably even with sweaty fingers, in the rain, or while wearing gloves, whereas capacitive touch panels tend to malfunction or trigger unintentionally under precisely these conditions.
App Integration: SOUNDPEATS App and PeatsAudio
You can customize the sound of the UU2 using the SOUNDPEATS app, which is sometimes referred to as the PeatsAudio app in reviews. For a model in this price range, the range of features is surprisingly extensive:
- Several preconfigured EQ presets for different music genres
- A multi-channel equalizer for manual fine-tuning
- Dynamic EQ, which automatically adjusts bass response based on volume
- Adaptive EQ, which is designed to adapt the sound to the shape of your ears
- Spatial Audio for a more immersive sound experience—though reviews tend to describe it as a solid additional feature rather than a standout feature
- Privacy Mode and Game Mode for calls and reduced latency during gaming, respectively
- Firmware updates directly through the app
It’s the combination of Dynamic EQ and a multi-channel equalizer in particular that sets the UU2 apart from many budget competitors, which often offer only a few fixed presets to choose from.
Battery Life of the UU2
In terms of battery life, the Soundpeats UU2 performs above average for its price range: According to the manufacturer, 50 mAh per earbud and 500 mAh in the charging case provide up to 10 hours of playback per charge and a total of up to 42 hours, including multiple recharges via the case. If you actively use the LDAC codec, you can expect about 7 to 8 hours per charge. This is a common trade-off, as high-resolution audio transmission consumes more power.
The fast-charging feature is handy for everyday use: 10 minutes in the case should provide about 2 hours of playback time. That’s enough to quickly top them off before a spontaneous run or if you’ve forgotten to charge them. The earbuds themselves are fully charged in about 45 minutes, and the case in about 1 hour and 36 minutes via USB-C.
Sound Quality of the Soundpeats UU2
Surprise: For an open, clip-on design, the Soundpeats UU2 delivers a surprising amount of bass. Sonically, you can expect a bright, treble-heavy sound with a wide but rather low soundstage. The bass is surprisingly present and rich, without sacrificing detail: If the earbuds fit perfectly, they deliver noticeable dynamic contrasts; however, if they sit too close to the ear canal, the bass can sound muffled. Overall, the sound is full-bodied, even if it naturally doesn’t quite match that of closed-back in-ear earbuds.
The mids come across as full and forward, with a surprisingly high level of detail for this design. Drums and percussion sound lively and full. Few open-ear headphones manage this so well. In the high frequencies, the sound can occasionally come across as slightly harsh or metallic at high volumes or with very bright recordings, but the highs generally remain well-controlled. Another plus: The UU2 plays unusually loud for its design. You’ll rarely need the maximum volume; usually, around 50–60 percent of the maximum output is perfectly sufficient. This is also surprising, since open-ear earbuds typically play at a lower volume.
All in all, I really like what the UU2 delivers to my ears. While Soundpeats doesn’t quite reach the level of its significantly more expensive competitors here, the earbuds deliver a truly balanced overall sound. Especially if you do a little fine-tuning using the equalizer.
Microphone Quality and Noise Cancellation
For calls and voice assistants, the UU2 features up to two microphones per earbud with AI-powered noise cancellation (ENC), which is designed primarily to filter out wind and ambient noise. However, the overall features and sound quality with ENC are solid for this price range and are on par with what competitors offer in this segment.
Soundpeats UU2 Review: Conclusion
The UU2 demonstrates that Soundpeats has taken its entry-level open-ear model a significant step forward: more bass, higher resolution, and a surprisingly feature-rich app with Dynamic EQ and LDAC support—features rarely found in this price range. The physical buttons instead of touch controls and the solid battery life of up to 42 hours round out the package for sports and everyday use.
In terms of sound quality, you get a lot for the price, and you can also make fine adjustments via the app if desired. The microphones, on the other hand, are just okay, and occasional connection dropouts are a bit annoying. For the price, however, the UU2 remains an interesting entry point into open-back earbuds.
PROS
- Powerful bass (for open-ear)
- Good, vibrant sound
- Excellent wearing comfort
- Comprehensive app
- Bluetooth 6.0 with LDAC
CONS
- Occasional connection dropouts
- Control button quite small
- Microphones just okay
- Minor software bugs
Conclusion
The Soundpeats UU2 offer an impressive feature set for under $70: Bluetooth 6.0, LDAC, long battery life, and excellent wearing comfort. A clear recommendation for open-ear headphone newcomers with solid value for money.
