Ramso LS-SL70: A Budget-Amiable Mono Bluetooth Headset for Professionals
In today’s dynamic work environment, the phone call remains a vital dialog tool.While true wireless stereo (TWS) earbuds dominate the market, mono Bluetooth headsets, worn in a single ear, continue to serve a specific need, notably for professionals who spend meaningful time on calls.
The Mono Bluetooth Market: A Niche Dominated by Legacy Brands
The TWS market is ruled by giants like Apple and Samsung,the mono bluetooth space is primarily occupied by established companies such as Jabra and Plantronics (now Poly). These brands have built reputations for call quality and battery life, crucial factors for business users.
Did you know? Mono Bluetooth headsets are often preferred in professional settings where users need to maintain awareness of their surroundings while staying connected.
However, Jabra’s product releases have slowed, and plantronics (Poly) headsets can be expensive, especially when purchased individually rather than through corporate channels. This gap in the market has created an prospect for domestic brands like Ramso.
First Impressions and Design: Familiar Territory




The Ramso LS-SL70 arrives well-packaged, including the headset itself, a USB-C charging cable, six different sizes of eartips, and a user manual. While the design is functional,it bears a resemblance to existing premium mono headset brands. The product has received domestic KC certification.


A key feature is the 180-degree rotating speaker, allowing the headset to be worn comfortably on either the right or left ear. This adaptability sets it apart from many conventional mono headsets.
Technical Specifications: Impressive Features for the Price
The Ramso LS-SL70 boasts a solid set of technical specifications:
- Chipset: Qualcomm Premium Bluetooth 5.2 + EDR
- Codec support: APTX, SBC, AAC
- Microphone: Dual microphone with noise canceling (claims 99% noise reduction)
- Battery Life: Up to 27 hours on a full charge
- Charging: USB-C and magnetic charging support
- Water Resistance: IPX4
- multi-Pairing: Connects to up to two devices simultaneously
The inclusion of a Qualcomm chipset and APTX codec support is particularly noteworthy at this price point. APTX offers improved audio quality compared to the standard SBC codec, a significant advantage for call clarity and overall sound.
Real-World Experience: Comfort and Call Quality Shine
Comfort is a standout feature of the LS-SL70. For users who wear headsets for extended periods, this is crucial. It is indeed a great advantage that your ears are hardly hurt after wearing this for a long time.
Unlike some similar products that cause discomfort after just a few hours, the Ramso LS-SL70 remains agreeable even after prolonged use.

call quality is paramount for a mono Bluetooth headset. The LS-SL70 excels in this area, thanks to its dual-microphone noise canceling system and boom microphone design. If it’s a call quality, it can be said to be heard by the other person rather than the sound of me.
The boom microphone positions the microphone close to the mouth, ensuring clear voice transmission, even in noisy environments.
Pro Tip: For optimal call quality, ensure the boom microphone is properly positioned close to your mouth.
Battery life is also impressive, delivering on its advertised 27-hour capacity. Fast charging adds to the convenience.
Multi-pairing functionality is a valuable asset for professionals. Connecting to both a work phone and a personal phone, or a computer and a smartphone, streamlines communication and enhances productivity, especially during virtual meetings.
Price and Value: A Compelling Proposition
The Ramso LS-SL70 offers a competitive price-to-performance ratio. It undercuts the prices of comparable Jabra and Plantronics (Poly) models without sacrificing call quality or battery life.
However, there is room for advancement in brand recognition and software support. Users should not expect the advanced settings or enterprise management features found in professional business headsets from established brands. These are areas where Ramso could invest to further enhance its product offering.
Final Verdict: A Practical and Affordable Choice

The Ramso LS-SL70 is a solid option for those seeking an affordable mono Bluetooth headset. In a market where mono headsets remain relevant for office use, and where Jabra’s offerings are limited and Plantronics (Poly) products are expensive, the LS-SL70 fills a crucial need.
While the design may draw inspiration from other brands, the headset delivers satisfactory performance in practical areas such as call quality, battery life, and comfort. The rotatable earpiece and dual-microphone noise canceling are significant advantages.
The Ramso LS-SL70 is best described as a modest and ample
product. It is a recommended choice for consumers who want quality without the high price tag of premium brands.
