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 inclusion of Bluetooth connectivity allows for wireless audio streaming from smartphones, tablets, and laptops. This provides greater flexibility and convenience, eliminating the need for cables. The Bluetooth range is specified as 50 meters, offering a reliable connection.

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

These speakers are powered by a 12V DC corded electric adapter, not USB. This may require an additional power outlet but allows for a more stable and powerful power supply compared to USB-powered speakers, potentially leading to better sound quality and bass performance.

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

These speakers do not have a headphone jack. Users who frequently use headphones for private listening may find this a significant drawback, as they will need to disconnect the speakers to use headphones with their audio source.

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 wireless touchpad provides a convenient way to control the volume from anywhere in the room. The inclusion of physical buttons on the speakers themselves offers an alternative control method. This ensures easy access to volume adjustments regardless of the user's location.

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 inclusion of a 3.5mm auxiliary input allows for connection to devices that do not support Bluetooth. This ensures compatibility with older devices, MP3 players, and other audio sources. This provides versatile connectivity options for various devices.

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

These speakers do not have an automatic power-off function. This means that they will remain on until manually turned off, potentially leading to unnecessary power consumption if forgotten. Users should remember to manually power off the speakers when not in use.

SHOPSTAFF Rating Score

Ranked #5 out of 100 products in Category

4.2

Overall Rating

The KEiiD KD-C02 offers a stylish design and good sound quality for its price range. The wireless subwoofer and touchpad are nice additions, but the overall sound performance may not satisfy audiophiles. It's a good value for casual listening and gaming.

Sound Quality (Frequency Response)

4.3

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 good sound quality with clear highs and a decent bass response thanks to the wireless subwoofer. The inclusion of dome-silk tweeters contributes to crisp audio. The 4 EQ modes allow for some customization, enhancing the listening experience for various content types.

Wattage (Power Output)

4.0

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 40 Watts, these speakers are suitable for small to medium-sized rooms. The 20W subwoofer provides adequate bass for most users. However, those seeking very high volumes or extremely powerful bass may find the output somewhat limited.

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 Bluetooth and a 3.5mm auxiliary input provides versatile connectivity options. Bluetooth allows for wireless streaming from various devices, while the 3.5mm jack ensures compatibility with older devices or those without Bluetooth.

Speaker Configuration (2.0, 2.1)

4.6

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 2.1 configuration, with dedicated left and right speakers plus a wireless subwoofer, delivers a well-rounded audio experience. The subwoofer enhances the bass response, making it suitable for gaming, movies, and music genres that benefit from strong bass.

Physical Size and Design

4.7

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 speakers feature a sleek and modern design that fits well in both casual and professional setups. The compact size of the satellite speakers makes them suitable for desktops with limited space, while the wireless subwoofer can be placed under the desk for convenience.

Controls and Features (Volume, EQ, Headphone Jack)

4.4

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 wireless touchpad control is a convenient feature, allowing for easy volume adjustments and settings changes from anywhere in the room. The inclusion of 4 EQ modes (News, Music, Movie, Game) provides some customization options. However, there is no headphone jack.

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

KEiiD is a relatively new brand, so its long-term reliability is uncertain. The limited warranty provides some assurance, but users have reported difficulties contacting the manufacturer. It is important to consider this when evaluating the product.

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 $119.99, the KEiiD KD-C02 offers a good balance of features, performance, and style. The wireless subwoofer, touchpad control, and multiple EQ modes provide excellent value for the price. It is a worthwhile upgrade for those seeking enhanced audio.
