AI Verdict
These are 2.29-ounce clip-on, open-ear Bluetooth 6.0 earbuds with 6 hours of playtime per charge, designed for secure fit during activity and clear calls.
The open-ear, clip-on design is specifically engineered for a secure fit during activity and compatibility with glasses, making it a strong choice for those specific needs. However, the 2.29-ounce weight per earbud and reports of irritation after an hour suggest it's not a universal fit for all-day comfort for every user. It excels in niche scenarios but has limitations for general prolonged use.
If all-day comfort and lighter weight are priorities, look for earbuds under 10 grams per earbud, or consider traditional in-ear designs if ambient awareness isn't critical.

Pros
- Open-ear design allows ambient sound awareness, enhancing safety during outdoor activities.
- Clip-on structure provides a secure, shake-proof fit for running, workouts, and cycling.
- Dual-Mic ENC Noise Cancelling technology ensures crystal-clear calls in noisy environments.
- Bluetooth 6.0 offers ultra-stable connections, faster pairing, and lower latency for media.
- IPX5 waterproof rating protects against sweat, rain, and intense workouts.
- Provides up to 50 hours of total playtime with the charging case.
Cons
- The 2.29-ounce weight per earbud is significantly heavier than typical earbuds, potentially causing discomfort over time.
- Sound quality is described as adequate for casual listening but lacks strong bass and can be tinny at higher volumes.
- Active Noise Cancellation for listening is not effectively implemented, with focus solely on ENC for calls.
- Some users report the clip-on design can become irritating behind the ear after an hour of wear.
Dimension Scores
The 13mm drivers deliver adequate audio for casual listening, but bass is weak and clarity diminishes at maximum volume, falling below average for music enjoyment.
While featuring ENC for clear calls, there is no effective active noise cancellation for the listener, making them poor for blocking environmental sounds during audio playback.
The clip-on design offers a secure fit for activity, but the 2.29-ounce weight per earbud and reports of irritation after an hour prevent higher comfort scores for prolonged use.
Providing 6 hours on a single charge and an impressive 50 hours total with the charging case is above average for budget wireless earbuds.
Best For
- Individuals needing secure-fitting earbuds for running, cycling, or gym workouts.
- Users who prioritize environmental awareness while listening to audio.
- People who make frequent calls in varied environments and need clear voice transmission.
- Glasses wearers seeking earbuds that don't interfere with their frames.
Not Recommended For
- Audiophiles seeking rich bass, detailed highs, or immersive sound quality for music enjoyment.
- Users who require active noise cancellation to block out ambient sound for focused listening.
- Anyone sensitive to ear pressure or discomfort from a 2.29-ounce earbud during extended use.
Watch Out For
- The 2.29-ounce weight per earbud is substantial, potentially leading to ear fatigue or discomfort for some users, despite claims of lightness.
- Sound clarity suffers at maximum volume, making them unsuitable for critical listening or high-volume environments.
- The clip-on design, while secure, can become irritating behind the ear after approximately an hour of continuous wear for some individuals.
- The advertised 'Active Noise Cancellation' primarily refers to ENC for calls, not noise reduction for the listener, which can be misleading.

What Buyers Say
The most striking finding from user feedback is the significant discrepancy between the advertised 'feather-light' feel and the actual 2.29-ounce weight per earbud, which can lead to discomfort after about an hour of wear for some users. Despite this, the secure clip-on design is consistently praised for keeping the earbuds in place during physical activity. Sound quality is generally considered acceptable for podcasts and calls, but falls short for music enthusiasts, with weak bass and clarity issues at higher volumes. The open-ear design is a key selling point, allowing users to remain aware of their surroundings.
“Okay, these clip-ons stay on my ears during my morning run, which is all I really cared about, but after an hour, my ears are kinda sore from the clip, and the music sounds just… there. Not bad for calls though.”
Common Praise
- Stays firmly in place during runs and workouts, preventing them from falling out.
- Allows hearing ambient sounds, which is safer for outdoor activities like cycling.
- Microphone quality is clear for phone calls, even in windy conditions.
- Bluetooth pairing is straightforward and connections are stable with minimal dropouts.
- The charging case provides substantial additional power, extending total playtime to 50 hours.
Common Complaints
- The clip-on design can cause irritation or slight pain behind the ear after extended use, around an hour or more.
- Sound quality is not for audiophiles; bass is weak and highs can sound tinny.
- Clarity of audio decreases noticeably at maximum volume levels.
- The 2.29-ounce weight per earbud makes them feel heavier than expected, contradicting 'feather-light' descriptions.
Ownership Tips
- The LED digital display on the charging case shows real-time battery levels for the case and earbuds.
- The earbuds automatically connect to your device in seconds after being removed from the case.
- The touch controls are precise, reducing accidental commands during use.
- The open-ear design means sound leakage is minimized by directional acoustic technology, but not entirely eliminated in quiet environments.
Frequently Asked Questions
Are these earbuds truly open-ear?
Yes, they feature an open-ear design that allows you to hear your surroundings while listening to audio, which is beneficial for safety during outdoor activities.
How long does the battery last on a single charge?
You get up to 6 hours of playtime on a single charge, with the charging case extending the total playtime to 50 hours.
Can I wear these with glasses?
Yes, the redesigned extended ear hooks are specifically made to be longer and thinner, eliminating discomfort and allowing comfortable wear with glasses.
Do these earbuds have Active Noise Cancellation?
The earbuds feature Dual-Mic ENC Noise Cancelling, which is for ensuring crystal-clear calls by reducing background noise for the microphone, not for active noise cancellation for your listening experience.
Are they suitable for intense workouts or running?
Yes, with an IPX5 waterproof rating and a secure, shake-proof clip-on fit, they are designed to handle sweat, rain, and stay in place during intense workouts, running, and cycling.
Buying Guide
When looking at open-ear clip-on earbuds like these, you need to think about how they'll actually feel and sound for *your* specific use. The 'open-ear' part means you'll hear your surroundings, which is a safety feature for runners or commuters, but it also means no noise isolation. The 'clip-on' design is all about stability, so if your current earbuds fall out, these might be a solution, but consider the weight and potential pressure points for long listening sessions.
Open-Ear Design
Unlike traditional earbuds that seal your ear canal, open-ear designs sit outside, letting you hear traffic or conversations. This is like having a conversation with someone while music plays softly in the background, keeping you aware of your environment.
Bluetooth 6.0
This refers to the wireless connection standard. Bluetooth 6.0 means a more stable and faster connection to your phone or device, reducing audio dropouts and lag, similar to having a strong Wi-Fi signal for your laptop.
IPX5 Waterproof
This rating indicates how well the earbuds resist water. IPX5 means they can handle splashes, sweat, and light rain, so you don't have to worry about them getting damaged during a sweaty workout or an unexpected drizzle.
ENC (Environmental Noise Cancellation)
This technology specifically targets the microphone, reducing background noise so the person on the other end of your call hears your voice more clearly. Think of it like a filter that cleans up your voice when you're talking in a noisy coffee shop.
Alternatives
If you need better sound quality for music or true active noise cancellation for quiet listening, search for in-ear earbuds with larger dynamic drivers or dedicated ANC features. If the 2.29-ounce weight is a concern, look for earbuds explicitly advertised with a per-earbud weight under 10 grams.
