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

This speaker does not have Bluetooth connectivity. This limits its ability to connect wirelessly to devices like smartphones or tablets. Users who want wireless audio will need to consider other options. The lack of Bluetooth helps keep the cost down, focusing on basic wired connectivity.

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 speaker is powered via USB, making it easy to connect to computers and laptops without needing a separate power adapter. This simplifies setup and reduces cable clutter. It's a convenient feature for users with limited desk space or power outlets. The USB connection also provides the audio signal.

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

This speaker does not have a headphone jack. This means you cannot directly connect headphones for private listening. Users who frequently use headphones may find this a significant drawback. You would need to connect headphones directly to your computer instead.

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 speaker has volume control, allowing you to easily adjust the sound level. The touch controls are conveniently located on the speaker bar. This makes it easy to quickly change the volume without having to use your computer's controls. The volume range is adequate for most listening situations.

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

This speaker does not have an external input function (e.g., 3.5mm AUX port). This limits its ability to connect to older devices or devices without USB. Users who need to connect to a variety of audio sources may find this a limitation. It is designed primarily for use with computers via USB.

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

This speaker does not have an automatic power-off function. This means it will remain on as long as it's connected to a power source. Users who are concerned about energy consumption may need to manually turn it off when not in use. This is a minor inconvenience but worth noting.

SHOPSTAFF Rating Score

#79

Ranked #79 out of 100 products in Category

3.1

Overall Rating

The Cyber Acoustics CA-2890 is a budget-friendly speaker bar that offers decent sound quality for its price. It's a good option for users looking to declutter their desks and improve their computer's audio without spending too much. The build quality is acceptable, but durability may be a concern with long-term use. It's suitable for basic audio needs like video calls and casual music listening.

Sound Quality (Frequency Response)

3.0

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 sound quality is decent for its size and price, providing clear audio for basic use cases. However, it lacks the depth and richness of higher-end speakers, with limited bass response and a narrower frequency range. It's suitable for casual listening but not for critical audio applications.

Wattage (Power Output)

2.5

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 maximum output of 2 Watts, this speaker is best suited for small spaces and close-range listening. It may not be loud enough to fill a larger room or overcome significant background noise. The low wattage contributes to its compact size and USB power convenience.

Connectivity Options (USB, 3.5mm, Bluetooth)

1.5

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 speaker connects via USB, which provides both power and audio signal. While this simplifies setup, it limits connectivity options compared to speakers with 3.5mm or Bluetooth. The included USB-A to USB-C adapter enhances compatibility with newer devices.

Speaker Configuration (2.0, 2.1)

3.5

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

As a 2.0 speaker, it delivers stereo sound without a separate subwoofer. This configuration is adequate for general use, but lacks the immersive experience and enhanced bass of a 2.1 system. The stereo separation is noticeable, but not exceptional.

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 compact size and monitor-mounting design are major strengths, saving valuable desk space. The speaker bar is lightweight and unobtrusive, blending well with most monitor setups. The ability to stand alone on a desk adds to its versatility.

Controls and Features (Volume, EQ, Headphone Jack)

3.0

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 touch controls for volume and mute are convenient and easily accessible. However, the speaker lacks advanced features like EQ controls or a headphone jack. The LED indicator for mute status is a useful addition.

Manufacturer Reliability and Warranty

3.0

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

Cyber Acoustics is a known brand, but not considered top-tier. The one-year warranty provides some assurance, but long-term reliability may be a concern given the price point. Customer support experiences can vary.

Cost Performance

4.0

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 its price point, the Cyber Acoustics CA-2890 offers good value for basic audio needs. It's a cost-effective solution for users prioritizing desk space and simple connectivity over high-end sound quality. The inclusion of a USB-C adapter adds to its appeal.
