After spending time using the Shidu S617 Voice Amplifier, I can confidently say that this compact yet powerful device is an excellent tool for individuals who need to project their voice clearly and effectively. Whether you’re a teacher addressing a classroom, a tour guide leading a group, or a coach motivating a team, the S617 stands out as a reliable and versatile solution for voice amplification. Priced at Rs. 1249, it offers incredible value for its features. Here’s my in-depth review based on my experience with the device.
What’s In the Box?
Shidu has thoughtfully included several accessories in the package, ensuring you have everything you need to get started. The box contains:
- 1 Voice Amplifier
- 1 Wired Microphone
- 1 Type-C Charging Cable
- 1 Strap
- 5 Sponges for the microphone
Design and Build Quality: Compact and Lightweight
One of the first things I noticed about the Shidu S617 is its compact size and lightweight build. Measuring just 10.1 x 8.75 x 5.0 cm and weighing only 205 grams, it’s incredibly portable. The device is thoughtfully designed to ensure ease of use. With the included rear clip, you can conveniently attach it to your belt or pocket. Alternatively, the provided strap allows you to hang it around your neck, ensuring you can carry it comfortably wherever you go.
Despite its small size, the device feels sturdy and durable. The build quality ensures that it can withstand daily use in various environments, from classrooms to outdoor settings. The minimalist design and thoughtful ergonomics make it user-friendly for all age groups.
Performance: Loud and Clear Output
The performance of the Shidu S617 is where it truly shines. It features a built-in 4Ω 5W 3-inch speaker that delivers a clear and loud output of up to 16W, making it suitable for addressing small to medium-sized groups. The device offers a frequency response range of 80Hz to 18kHz, ensuring that your voice sounds natural and crisp.
During my testing, I found the sound quality to be excellent, with no noticeable distortion even at higher volumes. The clarity of the output makes it ideal for use in noisy environments, such as outdoor events or bustling classrooms.
Battery Life: Long-lasting and Reliable
One of the standout features of the Shidu S617 is its long battery life. It is powered by a 3.7V, 1800mAh rechargeable lithium battery, which provides 10-12 hours of amplification and 6-10 hours of music playback on a single charge. The battery fully charges in about 3-4 hours via the included Type-C charging cable, which is a welcome upgrade for fast and convenient charging.
I found the battery life to be more than sufficient for an entire day’s use, whether I was using it continuously for teaching or intermittently during events. This long-lasting battery makes it a reliable companion, especially in situations where access to charging is limited.
Bluetooth 5.0 and AUX Input: Enhanced Versatility
The inclusion of Bluetooth 5.0 support is another feature that adds to the versatility of the Shidu S617. I was able to pair it with my smartphone seamlessly and use it as a portable speaker to play music or prerecorded audio. The Bluetooth connection was stable and had a decent range, making it convenient to use in larger spaces.
For those who prefer wired connections, the device also supports AUX input, allowing you to connect it to multiple devices, such as laptops or MP3 players. This flexibility makes the S617 more than just a voice amplifier—it doubles as a versatile audio playback device.
Wired Microphone: Practical and Effective
The Shidu S617 comes with a wired microphone that has a flexible design, allowing you to position it close to your mouth for optimal sound pickup. The microphone performed admirably, capturing my voice clearly without any static or interference. The wired connection also ensures consistent performance without the risk of signal loss.
The microphone’s ergonomic design and adjustable arm make it comfortable to wear for extended periods. Whether you’re moving around a classroom or addressing an audience, the microphone stays securely in place.
Unique Features: One-Key Mute and Stable Performance
The one-key mute function is a simple yet invaluable feature. It allows you to instantly mute the device with the press of a button, which I found incredibly useful during breaks in speeches or when transitioning between activities. This feature adds a layer of professionalism and control, especially in formal settings like conferences or training sessions.
Another notable aspect of the Shidu S617 is its stable performance. Throughout my use, the device consistently delivered reliable amplification without any glitches. It’s well-suited for various scenarios, including teaching, training, yoga classes, speeches, and even outdoor events.
Practical Usage Scenarios: A Multi-Purpose Device
The versatility of the Shidu S617 makes it suitable for a wide range of applications. Here are some scenarios where I found it particularly useful:
- Teaching: The device effortlessly projects your voice across the room, ensuring that every student can hear you clearly without straining your voice.
- Tour Guiding: The lightweight design and portability make it ideal for tour guides who need to address groups while on the move.
- Fitness Training: Whether you’re conducting a yoga class or leading a workout session, the S617 ensures your instructions are heard over background noise.
- Public Speaking: For speeches and presentations, the S617 delivers clear and impactful audio, making it easier to engage with your audience.
- Music Playback: When paired with a smartphone via Bluetooth, the device doubles as a compact speaker, making it great for playing music or audio clips during sessions.
These accessories enhance the overall user experience and provide added convenience. The inclusion of a Type-C charging cable is particularly noteworthy, as it aligns with modern charging standards and ensures faster charging times.
Limitations: Areas for Improvement
While the Shidu S617 performs exceptionally well in most areas, there are a few minor limitations worth noting:
- No Wireless Microphone: Although the wired microphone delivers excellent performance, the addition of a wireless microphone option would have been a nice touch for greater mobility.
- Limited Bass Response: While the sound quality is clear, the bass response is somewhat limited due to the small size of the speaker. This might not be a concern for voice amplification but is noticeable when playing music.
Final Verdict: A Must-Have for Voice Amplification
Overall, the Shidu S617 Voice Amplifier is a well-rounded device that excels in portability, performance, and versatility. Its compact design, long battery life, and Bluetooth connectivity make it a valuable tool for anyone who needs reliable voice amplification.
Whether you’re a teacher, trainer, or public speaker, the Shidu S617 offers a practical and effective solution that ensures your voice is heard loud and clear. While it could benefit from a few additional features, such as a wireless microphone, these are minor trade-offs for a device that performs so well in its primary function.
For its price and feature set, the Shidu S617 is a solid investment that delivers excellent value. If you’re looking for a dependable voice amplifier that’s easy to use and packed with useful features, the S617 is a fantastic choice.
