Design and Build
The core design innovation of the Assistrust KY8000E is its splitable soundbar. The main unit separates into two individual speakers, allowing for unconventional placement options beyond the traditional single bar beneath a TV. According to the manufacturer, this enables four acoustic optimizations: a horizontal setup for studio-grade clarity, a vertical orientation for concert-hall immersion, a tabletop configuration for intimate vocal focus, and a wall-mounted placement for a 3D surround effect. The system includes two bases for the detached speakers.
The build includes a wired subwoofer, which is a separate unit connected to the main soundbar via a cable. This wired connection provides the deep bass but limits placement flexibility compared to a wireless subwoofer. The overall aesthetic is a standard black finish, with the soundbar measuring 31 inches in length when assembled. The packaging includes all necessary cables for connectivity: HDMI ARC, optical, and a 3.5mm AUX cable, along with a remote control.
Performance and Features
Audio Output and Sound Modes
With a combined 110W output from its four drivers and the dedicated subwoofer, the KY8000E aims to deliver powerful, distortion-free sound. A key feature is the three customizable EQ modes designed for different content. Movie mode is tuned for cinematic depth and dynamic range, Music mode emphasizes richer notes and deep rumbles, and News mode focuses on natural tones and vocal clarity for podcasts and talk shows. The system also includes Bass Boost and Volume Boost features to further amplify low-end response and overall loudness.
Connectivity and Compatibility
Connectivity is a strong point, offering multiple ways to link to source devices. It supports modern Bluetooth 5.3 for wireless streaming from smartphones or tablets. For televisions, it provides HDMI ARC (Audio Return Channel), optical, and standard 3.5mm AUX inputs. When using the ARC connection, a significant convenience feature is activated: the soundbar can be controlled using the existing TV remote for power and volume. However, the manufacturer provides a crucial compatibility note: the TV must have an ARC-labeled HDMI port (not a standard HDMI 1 or 2 port), and the TV’s audio output format must be set to PCM for the soundbar to function correctly, indicating it is not a universal plug-and-play device.
Key Feature Integration
The detachable design is the standout feature, promoting acoustic flexibility. The wired subwoofer is tasked with delivering the “epic bass,” intended to make users feel the sound for movies and intensify gaming moments. The multiple placement strategies—horizontal, vertical, tabletop, wall-mounted—are presented as tools to optimize sound for different room layouts and listening preferences.

Setup, Support and Ownership
Setup requires attention to detail, primarily regarding TV settings. As highlighted in the manufacturer’s notes, users must ensure their TV’s audio output is set to an external speaker/soundbar and the output format is switched to PCM or stereo. These settings vary by TV brand and model. The included 18-month warranty and promise of 24/7 online technical support are part of the ownership package to assist with compatibility issues. The product is designed for use with a wide range of input voltages (100-240V), making it suitable for various regions. No information is provided by the manufacturer regarding firmware updates or additional accessory options.
What Owners Say
Owner feedback, reflected in the 4.2 out of 5-star rating, is generally positive. A high percentage of reviews award five stars, praising the system’s value, powerful bass from the subwoofer, and clear sound quality. Multiple users highlighted the ease of setup and the versatility offered by the multiple connection options, including a completely wireless Bluetooth setup. Positive comments frequently mention the detachable design and the substantial build quality relative to the price point.
The distribution of ratings shows a smaller portion of critical feedback. Some lower-star reviews point to challenges with initial setup and compatibility, echoing the manufacturer’s warnings about required TV settings. A minor noted drawback from users is the lack of a volume level display on the TV, requiring adjustment by ear. Overall, the consensus among owners is that the Assistrust KY8000E delivers a significant audio upgrade for the money, particularly for its deep bass and flexible design.

Who Should Buy It (and Who Should Skip It)
The Assistrust KY8000E is an excellent fit for smart TV owners, gamers, and movie watchers who want a substantial audio upgrade with immersive bass and appreciate configuration flexibility. Its detachable design is ideal for users with unconventional entertainment setups or those who wish to experiment with speaker placement for optimal acoustics. It’s also suitable for users comfortable with adjusting their TV’s audio settings to ensure compatibility.
This soundbar may not be the best choice for users seeking the simplest, truly plug-and-play experience without any configuration. Those who require a completely wireless subwoofer for maximum placement freedom should look for models with that specific feature. Additionally, individuals with TVs lacking an HDMI ARC port or those unwilling to navigate audio output menus should consider a soundbar with more universal compatibility. For users prioritizing seamless multi-room audio, our resource on the best WiFi soundbars may offer more suitable alternatives.
Final Verdict
The Assistrust KY8000E soundbar system delivers on its core promise of transforming lackluster TV audio into a powerful, room-filling experience. Its standout detachable design offers genuine versatility for sound placement, while the included wired subwoofer provides the deep, impactful bass that is often missing from built-in speakers and cheaper soundbars. The combination of multiple EQ modes and extensive connectivity options, including modern Bluetooth 5.3 and convenient ARC control, makes it a highly adaptable centerpiece for movies, music, and gaming.
However, its value comes with a caveat: it demands a slightly more involved setup process. The requirement to configure TV audio settings to PCM and use the correct ARC port means it is not instantly compatible with every television out of the box. For users willing to spend a few minutes on setup, the KY8000E rewards them with a powerful, customizable, and immersive audio upgrade that punches above its weight class in terms of features and performance.

FAQs
Does the Assistrust KY8000E come with a separate subwoofer?
Yes, the KY8000E includes a wired subwoofer as part of the 2.1-channel system. The subwoofer is connected to the main soundbar unit via a cable, which provides the deep bass response but means its placement is tethered to the length of that cable.
What does “detachable design” mean for this soundbar?
The main soundbar unit can be physically separated into two individual speaker units. This allows you to place them in different configurations: together as a single bar, split left and right, placed vertically, or mounted on a wall. The goal is to offer flexible placement to optimize sound for your specific room layout.
Why is there no sound after I connect it to my TV?
The most common cause, as specified by the manufacturer, is incorrect TV settings. You must ensure your TV’s sound output is set to “External Speaker” or “Soundbar,” and critically, the audio output format must be changed to “PCM” or “Stereo.” Additionally, you must use the HDMI port on your TV that is specifically labeled “ARC” (Audio Return Channel).
Can I control the soundbar with my TV remote?
Yes, but only when the soundbar is connected to your TV using the HDMI ARC cable and the TV’s ARC port. In this mode, functions like power and volume can typically be controlled by your existing TV remote, reducing clutter. This feature does not work when using the optical or AUX connections.
