Bone Conduction vs Open-Ear Earbuds
Waterproof rating
You need reliable protection when exercising in wet conditions. The PSIER S18 offers an IPX8 rating, allowing it to be submerged in water up to two meters deep for one hour. This makes it suitable for serious swimming and underwater activities. In contrast, the Kinglucky Gen 3 Clip-On Earbuds carry an IPX5 rating. This level of protection handles sweat and rain effectively but does not support submersion. If you plan to swim laps or engage in water sports, the PSIER S18 provides the necessary durability. For general outdoor workouts where only sweat and light rain are factors, the Kinglucky model is sufficient.
Battery life
Total battery capacity varies significantly between these two designs. The Kinglucky Gen 3 Clip-On Earbuds provide up to 50 hours of total playtime when using the charging case, with a single charge lasting up to seven hours. This extended range reduces the frequency of recharging. The PSIER S18 bone conduction headphones deliver up to eight hours of continuous music playback on a single charge. While the PSIER charges fully in two hours via magnetic connection, it lacks a carrying case to extend that time. You should choose the Kinglucky option if you travel frequently or want multiple days of use without a charger. The PSIER is better for shorter, daily sessions.
Connectivity standard
Wireless transmission stability depends on the Bluetooth version used. The Kinglucky Gen 3 Clip-On Earbuds utilize Bluetooth 6.0 technology. This newer standard offers optimized anti-interference performance and stronger signal penetration, which helps eliminate high latency and frequent disconnections. The PSIER S18 relies on Bluetooth 5.4. While this version ensures ultra-low transmission latency and allows connection to multiple devices, it is an older specification than the 6.0 standard. For users prioritizing the latest wireless protocol and maximum signal stability, the Kinglucky earbuds hold a technical advantage. Both models support wireless connectivity, but the newer version in the Kinglucky device may offer more consistent performance in crowded areas.
Audio driver size
Driver size influences the potential for rich audio reproduction. The PSIER S18 bone conduction headphones are equipped with 14mm speaker drivers. These drivers aim to deliver rich audio through bone conduction technology. The Kinglucky Gen 3 Clip-On Earbuds feature 13mm dynamic drivers. These drivers use directional acoustic technology to minimize sound leakage and provide deeper bass. The PSIER S18 has a slightly larger driver specification at 14mm compared to the 13mm drivers in the Kinglucky model. However, the actual sound quality also depends on the transduction method. The PSIER uses bone conduction, while the Kinglucky uses open-ear dynamic drivers. For raw driver size, the PSIER S18 has the larger specification.
Music storage
Some users prefer to listen to music without their phone nearby. The PSIER S18 includes internal MP3 storage capable of holding up to 4,000 songs. You can switch to MP3 mode to listen phone-free, which is ideal for swimming or running without carrying a device. The Kinglucky Gen 3 Clip-On Earbuds do not list any internal storage capacity. They rely entirely on a Bluetooth connection to a paired device for audio playback. If you want the freedom to leave your phone at home or in a locker, the PSIER S18 is the only option that supports standalone listening. The Kinglucky model requires a connected source for all audio.
Choose the Right Open Ear Audio
Swimmers needing underwater music
The PSIER S18 features an IPX8 waterproof rating, allowing submersion up to two meters deep for one hour. It includes 32GB internal MP3 storage for phone-free listening. This setup ensures you can enjoy music while swimming without relying on a connected device.
Users wanting long battery life
The Kinglucky Gen 3 offers 50 hours of total playtime with its charging case. A single charge provides up to 7 hours of use. This extended battery capacity reduces the need for frequent recharging, making it ideal for long trips or extended daily commutes.
Listeners preferring latest Bluetooth tech
The Kinglucky Gen 3 utilizes Bluetooth 6.0 for stronger signal penetration and anti-interference. This newer standard helps eliminate high latency and frequent disconnections. You get a more stable wireless connection compared to the Bluetooth 5.4 found in the competing bone conduction model.
Runners prioritizing safety and awareness
The PSIER S18 uses bone conduction technology to keep your ears open to ambient sounds. This design lets you hear surrounding traffic and people while listening to music. It also includes an adjustable rope for a stable fit during intense running or sports activities.

Frequently asked questions
Are bone conduction headphones better for swimming than open ear earbuds?
Yes, if you plan to swim. The PSIER S18 features an IPX8 waterproof rating, allowing submersion up to two meters deep for one hour. It also includes 32GB of internal storage for phone-free listening. Open-ear clip-ons like the Kinglucky Gen 3 are waterproof but lack the specific underwater audio transmission and storage needed for serious swimming.
Which option is more comfortable for people who wear glasses?
Open-ear clip-ons are often a better fit. The Kinglucky Gen 3 is specifically noted as practical for glasses wearers. Its clip-on design avoids the pressure points that bone conduction headbands might create behind the ears or on the temples. This makes it a more comfortable choice if you wear eyewear during your activities.
Do I need a phone to use bone conduction headphones?
Not necessarily. The PSIER S18 includes 32GB of internal MP3 storage. This allows you to listen to music directly from the device without needing a connected phone. You can leave your phone behind while running or swimming. Other models may rely entirely on Bluetooth connectivity, requiring a paired device for audio playback.
How does the fit of open ear earbuds compare to bone conduction?
Open-ear clip-ons offer a different fit profile. The Kinglucky Gen 3 uses a clip-on design that sits on the outer ear. It measures 1.97 inches wide and weighs 2.29 ounces. Bone conduction devices rest on the cheekbones. The clip-on style may feel lighter and less intrusive for users with smaller ears or those who prefer minimal contact.
Can I use these devices for running in the rain?
Yes, both designs handle wet conditions well. The PSIER S18 has an IPX8 rating, making it suitable for heavy rain and swimming. The Kinglucky Gen 3 is also rated as waterproof. Both options keep your ears open to traffic sounds, which is safer for outdoor running. You can choose based on whether you need underwater capability.
What is the main difference in how they deliver sound?
They use different transmission methods. Bone conduction headphones vibrate against your cheekbones to send sound to the inner ear. Open-ear earbuds sit outside the ear canal and direct sound waves into it. Both methods leave your ear canals open to ambient noise. The choice depends on whether you prefer direct bone vibration or traditional open-air audio delivery.
