Design and Build
The littoak SE04 presents a straightforward, utilitarian design. Its 16.14-inch width and 2.87-inch height are purpose-built to sit discreetly in front of or below a smaller television screen, avoiding the visual dominance of larger soundbars. The black finish is standard for the category, intended to blend with most entertainment setups. Build quality from the specifications suggests a standard plastic enclosure, with mounting options listed as bar mount and plug mount, providing some flexibility for installation. The included remote control underscores a design philosophy centered on convenience, allowing adjustments from a distance.
Performance and Features
Connectivity and Ports
This is the standout aspect of the SE04. It offers an unusually broad selection of inputs for its size and price point. Users can connect via HDMI or Optical for digital audio from a TV, use the 3.5mm AUX or Coax inputs for other legacy devices, or utilize the single USB 2.0 port for direct media playback. Wireless connectivity is handled by Bluetooth, with a specified range of 10 meters. This versatility means it can serve as a hub for audio from a television, a gaming console, a laptop, or a smartphone, effectively reducing cable clutter for a multi-device desk or entertainment center.

Audio Performance and Modes
The soundbar is specified with a 2.1 or 3.1 channel configuration and features three dedicated EQ modes: Movie, Music, and Dialogue. The Movie mode is tailored for cinematic content, likely emphasizing surround sound effects. Music mode focuses on musical playback, while Dialogue mode prioritizes speech clarity, a common pain point with TV speakers. It includes a Bass Boost feature, though its impact is naturally constrained by the compact speaker size and the 5 Watts maximum output power per channel. This power rating indicates it is suited for near-field listening or small to medium-sized rooms rather than filling a large space.
Control and Operation
Control is dual-faceted: physical buttons on the unit itself and a dedicated infrared remote control. The remote allows users to switch between input sources, adjust volume, and select the desired EQ mode without approaching the soundbar. The manufacturer notes that for Bluetooth pairing, the BT button on the remote must be pressed for more than two seconds, a minor but important operational detail.
Setup, Support and Ownership
Setup involves selecting the correct cable (HDMI, Optical, or 3.5mm AUX are included) and configuring the soundbar to the corresponding input mode. A crucial setup note from the manufacturer is that when using the Optical or HDMI connection, the TV’s audio output must be set to “PCM” for compatibility. The package includes the soundbar, remote, optical cable, a 3.5mm cable, wall mount screws, and a user’s manual. There is no mention of a dedicated app for control or firmware updates, indicating a plug-and-play philosophy. The product comes with a one-year limited warranty, and customer service is highlighted in the features, suggesting support is available for setup or performance issues.
What Owners Say
Overall feedback for the littoak SE04 is positive, with users frequently praising the sheer number of connectivity options for such a compact and affordable unit. The improvement in sound clarity over standard TV speakers, particularly for dialogue, is a common theme. The compact size is also cited as a major benefit for those with space constraints. On the critical side, some users note that while it improves upon built-in speakers, the bass response is limited due to its small form factor, making it less ideal for action movie enthusiasts or bass-heavy music. The requirement to set the TV to PCM for digital audio and the specific Bluetooth pairing procedure are occasionally mentioned as minor setup hurdles.

Who Should Buy It (and Who Should Skip It)
The littoak SE04 is an ideal choice for users with small to medium-sized televisions, bedroom TVs, desktop PC setups, or projectors who are frustrated by weak or muddy built-in speakers. Its value shines for those who own multiple devices (TV, console, PC) and want a single, compact speaker system to handle them all via its myriad inputs. It’s also suitable for anyone prioritizing clearer dialogue for TV shows and news.
Conversely, it should be skipped by users with large living rooms who need powerful, room-filling sound with impactful bass for movies and music. Home theater enthusiasts seeking true surround sound or immersive Dolby Atmos experiences should look at more advanced systems. Those who desire seamless multi-room audio or smart speaker integration will not find those features here.

Final Verdict
The littoak SE04 soundbar successfully fulfills its core mission: providing a significant audio upgrade over basic TV or PC speakers in a compact, connection-rich package. Its strength lies not in raw power or deep bass, but in versatility and convenience. The ability to connect via almost any modern or legacy port reduces clutter and simplifies a home entertainment setup. The dedicated sound modes are a thoughtful addition that genuinely tailors the listening experience for different types of content.
Potential buyers must align their expectations with the product’s physical constraints. It is a solution for enhancement, not transformation. For small rooms, desktop use, or secondary TVs, it represents a sensible and feature-packed choice. For larger spaces or audiophile aspirations, its limitations in bass extension and output power will be apparent. Within its intended scope, the littoak SE04 stands out as a well-equipped and practical audio companion. Check out more audio gear reviews in our Tech Gear section.
FAQs
Can I connect the littoak SE04 to my TV wirelessly?
Yes, but with a caveat. The soundbar has Bluetooth connectivity, allowing you to stream audio wirelessly from a smartphone, tablet, or PC. However, most televisions do not transmit their audio output via Bluetooth. To use it wirelessly with a TV, you would typically need a separate Bluetooth transmitter plugged into your TV’s audio output. For a wireless TV connection, a soundbar with built-in Wi-Fi is often a more integrated solution.
Does it come with all the necessary cables to connect to my TV?
According to the specifications, the package includes an optical cable and a 3.5mm to 3.5mm AUX cable. An HDMI cable is not listed as included, so if you plan to use the HDMI connection (often the simplest for modern TVs), you may need to provide your own HDMI cable.
Can I wall-mount the littoak SE04?
Yes, the product specifications list “Bar Mount” and “Plug Mount” as mounting types, and wall mount screws are included in the box. The 16-inch width and lightweight design make it relatively easy to mount under a wall-mounted TV or on a wall near a projector screen.
What does “set TV audio output to PCM” mean and why is it necessary?
PCM (Pulse-Code Modulation) is a standard, uncompressed digital audio format. Some TVs output audio in other formats (like Dolby Digital) through their optical or HDMI ARC ports. The littoak SE04 requires the PCM format to decode the audio signal correctly. This setting is usually found in your TV’s Sound or Audio settings menu under “Digital Audio Out” or a similar option. Switching it to PCM ensures compatibility and prevents issues like no sound or distorted audio.
