Features

Bluetooth Connection Function

Feature Description

A function that allows wireless connection to devices such as smartphones and tablets via Bluetooth. You can easily play music without connecting cables. Convenient when you want to listen to music casually or remotely control the speaker.

About This Product

The Bluetooth connection function allows for wireless audio streaming from devices like smartphones and tablets, offering convenience and flexibility. The Bluetooth range is approximately 32.8 feet, providing a decent wireless range for most users. Setting up the Bluetooth connection is straightforward, enhancing the user experience.

USB Power Supply Function

Feature Description

A function that can be powered via a USB port on a computer or USB power adapter. It can be used easily by connecting to a computer without requiring a separate power adapter. Useful in environments where power outlets are limited.

About This Product

The USB power supply function simplifies setup by allowing the speakers to be powered directly from a computer or USB power adapter. This eliminates the need for a separate power outlet, reducing cable clutter and making the speakers more portable. This is especially useful in environments with limited power outlets.

Headphone Jack Function

Feature Description

A function that allows you to connect headphones or earphones. You can enjoy audio privately without disturbing others around you. Convenient when you want to concentrate on work or watch videos late at night.

About This Product

The absence of a headphone jack limits the ability to listen privately without disturbing others. This can be a drawback for users who frequently need to switch between speakers and headphones, as it requires disconnecting the speakers to use headphones. Consider this limitation if private listening is a priority.

Volume Control Function

Feature Description

A function that allows you to easily adjust the speaker volume. You can quickly adjust the volume to your preferred level. Useful when you want to respond to sudden changes in sound volume or environmental sounds.

About This Product

The volume control function is conveniently located on the front of the speakers, allowing for easy and accurate adjustments. The large volume rotate control button makes it simple to increase or decrease the volume as needed, enhancing the user experience. The placement and design of the volume control contribute to the overall ease of use.

External Input Function

Feature Description

A function that allows connection to external audio devices via an AUX or other input terminal. You can play audio from devices that do not support Bluetooth. Useful when you want to connect to older devices or devices without Bluetooth.

About This Product

The lack of an external input function, such as a 3.5mm AUX port, restricts connectivity to devices that only support USB or Bluetooth. This limitation may be a drawback for users with older devices or those without Bluetooth capabilities. Consider this if you need to connect to a variety of audio sources.

Automatic Power Off Function

Feature Description

A function that automatically turns off the power after a certain period of inactivity. Prevents unnecessary power consumption and saves energy. Provides peace of mind even if you forget to turn off the power.

About This Product

The absence of an automatic power-off function means that the speakers will continue to draw power even when not in use, potentially leading to unnecessary energy consumption. Users need to manually turn off the speakers to conserve power, which may be inconvenient for some. This feature would have added to the energy efficiency of the product.

SHOPSTAFF Rating Score

#29

Ranked #29 out of 100 products in Category

3.7

Overall Rating

The SENZER CS20 offers good sound quality and versatile connectivity at an affordable price. While it may not match the audio fidelity of higher-end models, it provides a solid audio experience for everyday use. The 2-in-1 design and RGB lighting add to its appeal, making it a good choice for budget-conscious users.

Sound Quality (Frequency Response)

3.8

Rating Criteria Explanation

The frequency response of computer speakers indicates the range of sound frequencies (measured in Hertz, Hz) that the speaker can reproduce. A wider frequency response generally means the speaker can reproduce a broader spectrum of sounds, from deep bass to high-pitched treble, resulting in a more detailed and realistic listening experience. For example, a speaker with a frequency response of 20Hz - 20kHz covers the entire range of human hearing. If you enjoy music with a lot of bass, like electronic music or hip-hop, pay attention to how low the frequency response goes. A lower number indicates deeper bass. Consider your primary use case: for general use, a standard range is fine, but for critical listening or music production, a wider, flatter frequency response is desirable to ensure accurate sound reproduction.

Rating Comments

The speakers offer clear stereo sound suitable for general use, but the bass response may be limited. The 20KHz frequency response provides decent audio clarity for music, movies, and gaming, though audiophiles may desire a wider range.

Wattage (Power Output)

3.5

Rating Criteria Explanation

Wattage indicates the speaker's power output, directly influencing its loudness. Higher wattage generally translates to a louder speaker that can fill a larger room without distortion. However, wattage isn't the sole determinant of loudness; speaker efficiency also plays a crucial role. A speaker with high wattage but low efficiency might not sound as loud as a lower-wattage, high-efficiency speaker. Consider the size of your room and your typical listening volume. For a small desk setup, low-wattage speakers (e.g., 5W) may suffice. For a larger room or for listening at higher volumes, consider speakers with higher wattage (e.g., 20W or more). Also, note that peak wattage is often advertised, which is the maximum power the speaker can handle for a short burst. RMS (Root Mean Square) wattage is a more accurate representation of the speaker's continuous power output.

Rating Comments

With a 10W maximum output, these speakers are adequate for small to medium-sized rooms. They provide sufficient loudness for desktop use, but may not be powerful enough for larger gatherings or environments with high ambient noise.

Connectivity Options (USB, 3.5mm, Bluetooth)

4.0

Rating Criteria Explanation

Computer speakers offer various connectivity options, each with its advantages and disadvantages. USB connectivity often provides a cleaner audio signal and can sometimes power the speakers directly, reducing cable clutter. A 3.5mm audio jack is a universal connection that works with most devices but can be more susceptible to noise. Bluetooth connectivity allows for wireless audio streaming from smartphones, tablets, and laptops, offering greater flexibility. Consider your devices and how you intend to use the speakers. If you want a simple setup with minimal cables, USB or Bluetooth might be preferable. If you need to connect to older devices or devices without Bluetooth, a 3.5mm jack is essential. Some speakers offer multiple connectivity options, providing greater versatility.

Rating Comments

The inclusion of both USB and Bluetooth connectivity offers versatile options for connecting to various devices. The USB plug-and-play feature simplifies setup, while Bluetooth allows for wireless streaming from smartphones and tablets.

Speaker Configuration (2.0, 2.1)

3.0

Rating Criteria Explanation

Speaker configuration refers to the number of speakers and their roles. A 2.0 system consists of two speakers (left and right) and provides stereo sound. A 2.1 system includes two speakers and a separate subwoofer for enhanced bass response. The choice depends on your listening preferences. 2.0 systems are suitable for general use and music listening where deep bass isn't critical. 2.1 systems are ideal for gaming, movies, and music genres that benefit from strong bass, such as electronic music and action movie soundtracks. Consider the space available on your desk. A 2.1 system requires more space for the subwoofer. Think about whether you prioritize clear stereo separation or emphasized bass.

Rating Comments

The 2.0 configuration delivers stereo sound, but lacks a dedicated subwoofer for enhanced bass. This setup is suitable for general use and music listening, but may not provide the immersive experience of a 2.1 system for gaming or movies.

Physical Size and Design

4.5

Rating Criteria Explanation

The physical size and design of computer speakers are important considerations, especially for desktop setups where space is limited. Compact speakers are ideal for small desks or laptops, while larger speakers generally offer better sound quality but require more space. The design should also complement your aesthetic preferences. Consider the available space on your desk and the overall look you want to achieve. Measure the dimensions of the speakers to ensure they fit comfortably in your workspace. Think about the placement of the speakers: will they be placed on either side of your monitor, or will they be mounted on stands? The design can also affect the sound dispersion. Some speakers are designed to project sound directly forward, while others offer wider sound dispersion.

Rating Comments

The 2-in-1 design offers flexibility in placement, allowing the speakers to be used as a soundbar or separated for stereo sound. The compact size saves desk space, and the RGB lighting adds a modern aesthetic touch.

Controls and Features (Volume, EQ, Headphone Jack)

3.5

Rating Criteria Explanation

The placement and type of controls are important for ease of use. Easily accessible volume controls are essential for quick adjustments. Some speakers also offer EQ controls to fine-tune the sound to your preferences. A headphone jack is a convenient feature for private listening. Consider where the controls are located (e.g., front, side, or remote). Front-mounted controls are generally more convenient. EQ controls allow you to adjust the bass, treble, and midrange frequencies to customize the sound. A headphone jack allows you to quickly switch between speakers and headphones without having to disconnect cables. Also, look for features like power on/off switch, mute button, and input selection.

Rating Comments

The easy-access volume knob provides convenient control, but the absence of a headphone jack limits private listening options. The RGB lighting modes add a visual element, but there are no EQ controls for fine-tuning the sound.

Manufacturer Reliability and Warranty

2.5

Rating Criteria Explanation

The manufacturer's reputation and the warranty offered are crucial indicators of product quality and reliability. Established brands with a history of producing high-quality audio equipment are generally a safer bet. A longer warranty period provides assurance that the manufacturer stands behind their product. Research the manufacturer's reputation for customer support. Check online reviews and forums to see what other users have experienced with the brand and their products. A good warranty should cover defects in materials and workmanship. Also, consider the ease of contacting customer support and the availability of replacement parts.

Rating Comments

SENZER is a relatively new brand, so long-term reliability is uncertain. The limited warranty provides some assurance, but it's advisable to research customer support experiences before purchasing.

Cost Performance

4.5

Rating Criteria Explanation

Cost-effectiveness is the ultimate balancing act. It's about finding the speakers that offer the best combination of features, performance, and quality within your budget. Don't just focus on the cheapest option; consider the long-term value. A slightly more expensive speaker that offers better sound quality and durability may be a better investment in the long run. Compare the features and specifications of different speakers in your price range. Read reviews to get an idea of the real-world performance. Consider the overall cost of ownership, including any accessories you may need (e.g., cables, stands). Ultimately, the best value is the one that best meets your needs and budget.

Rating Comments

At $24.99, these speakers offer excellent value for the price. The combination of features, sound quality, and design make them a compelling option for budget-conscious consumers seeking to upgrade their desktop audio experience.
