Sayrelances R20 PRO Bone Conduction Headphones: A Great Open-Ear Bluetooth Option for Swimmers

The sayrelances R20 PRO are open-ear bone conduction Bluetooth headphones designed for swimmers and active users. With 32GB of built-in storage, IPX8 waterproofing, and long 8 hour battery life, these lightweight headphones aim to provide quality audio during watersports and workouts without blocking ambient sounds.

Key Features

• Open-ear design allows situational awareness
• IPX8 waterproof and sweatproof
• 32GB built-in storage
• 8 hours battery life
• Lightweight (32.5g) and comfortable fit

Design and Comfort

Weighing just 32.5g, the sayrelances R20 PRO headphones have an open-ear fit that sits on your cheekbones rather than plugging your ear canal. This transmits sound by vibrating your bones instead of your eardrums, allowing you to hear both music and surrounding sounds simultaneously.

The flexible, lightweight band is adjustable to fit most head sizes comfortably. The headphones can even bend 360 degrees without deforming for a customized fit. For swimming and high movement activities, many users recommend wearing a swim cap over the headphones to keep them in place.

Features and Audio Quality

With Bluetooth 5.3 providing a stable wireless connection, the sayrelances R20 PRO headphones connect seamlessly to smartphones, tablets, and other Bluetooth devices. They can also store up to 10,000 songs locally with the 32GB MP3 storage.

Despite the bone conduction design, sound quality is surprisingly good - especially for sports use. Reviewers mention clear highs, solid bass, and minimal distortion even underwater when wearing earplugs. Volume may be lower than traditional headphones, but is adequate for listening during activities.

Battery Life and Charging

The sayrelances R20 PRO headphones boast an impressive 8 hours of continuous playback per charge. This is enough juice for several long workouts or swims. The sayrelances R20 PRO headphones fully charge in just 1.5 hours via the included magnetic USB cable.

Waterproofing

The IPX8 waterproof nano-coating protects the sayrelances R20 PRO headphones in up to 2 meters of water for 2 hours. While Bluetooth connectivity does not work underwater, you can easily switch to MP3 mode for uninterrupted music.

Use Cases

• Swimming
• Running
• Workouts
• Watersports
• Safe situational awareness during activities

User Feedback Analysis

The sayrelances R20 PRO headphones have received polarizing reviews, indicative of the risks and rewards of being an early adopter of newer bone conduction technology.

Positive reviewers praise the surprising sound quality, especially considering the bone conduction design. Many mention crisp highs, rich bass, and minimal distortion - exceeding expectations underwater when wearing earplugs. The open-ear comfort and ability to remain aware of surroundings are also highlights for runners and swimmers.

However, there are notable concerns around durability and connectivity. A number of reviewers experienced sudden issues with the headphones not turning on after several months of use. Others report intermittent Bluetooth dropping while swimming certain strokes where the headphones go deeper underwater.

While the waterproofing works well in principle, it seems the long-term water exposure may be damaging some units. Connectivity limitations while swimming are likely inherent to the bone conduction design that transmits audio through cheekbone vibration rather than direct ear canal sound waves.

Overall, when functioning properly, most users agree the sayrelances R20 PRO headphones deliver impressive audio andfeatures for swimming and workouts at this budget-friendly price point. But quality control and connectivity shortcomings under heavy water use will hopefully be improved in future generations.

Pros

• Open-ear design allows situational awareness
• Great for swimming and watersports
• 32GB MP3 storage
• IPX8 waterproof rating
• 8 hours battery life
• Lightweight and comfortable

Cons

Value

Priced around $50, the sayrelances R20 PRO headphones offer a compelling value proposition for those seeking an open-ear and waterproof workout headphone option. The decision boils down to your priorities - are upfront cost savings or long-term durability and connectivity more important?

For swimmers on a strict budget who plan to replace headphones annually, the sayrelances R20 PRO headphones feature set at this price is difficult to beat. However, those able to spend 2-3x more can find stronger waterproofing ratings and connectivity in premium competitors that may last multiple years.

Given the polarizing feedback, it’s best to purchase the sayrelances R20 PRO headphones with reasonable expectations around potentially shortened lifespan. But for the budget conscious open-ear headphone seeker, the value provided in features and audio quality per dollar spent is difficult to overlook.

With robust waterproofing, on-board storage, long battery life, and bone conduction technology delivering quality audio, these flexible headphones are ideal for workouts in and out of the water.

Frequently Asked Questions

Is internal storage sufficient for my music library?

The sayrelances R20 PRO Bone Conduction Headphones come with 32GB of internal storage, capable of holding approximately 10,000 songs in MP3, AAC, FLAC, or WAV formats. For most users, this provides more than enough space for their regular playlists. However, if you frequently update your music or have an extensive library, you might prefer streaming from a Bluetooth-connected device.

How well do these headphones stay in place during intense activity?

These headphones offer a secure, comfortable fit using bone conduction technology and an open-ear design. Customers have reported the headphones generally stay in place during most activities. However, some users find they need some adjustment after vigorous movements such as shaking their head. Using the included adjustment strap helps create the perfect fit for your head size. These headphones might need additional adjustments when used with certain swim goggles.

Do these headphones work well for phone calls?

While the sayrelances R20 PRO Bone Conduction Headphones support phone calls, users have reported mixed results. The clarity of calls may diminish in noisy environments as the open-ear design does not fully block out ambient sound. For frequent calls in louder environments, a traditional in-ear headset may be a better choice.

How does the sound quality compare to traditional earphones?

Bone conduction technology provides a different listening experience compared to in-ear or over-ear headphones. As sound is transmitted through the cheekbones, you may find the audio less rich in bass tones, but still clear and enjoyable. The primary benefit of this technology is that it allows you to stay aware of your surroundings, crucial for safety in many workout scenarios.

Can I use these underwater?

Yes! The IPX8 waterproof rating of the sayrelances R20 PRO Bone Conduction Headphones means they can withstand submersion in water. However, Bluetooth does not function underwater, so you’ll need to switch to the internal MP3 player mode for your swim workouts.

Tips

• Use the included earplugs: You’ll notice significant improvement in sound quality underwater by using the provided earplugs when swimming.
• Adjust for the perfect fit: Use the provided adjustment strap to get the best fit for your head, reducing the need for adjustments while active.
• Clean regularly: Rinse the headphones with fresh water after exposure to sweat, chlorine, or salt water.
