Hisense A620 2.1ch Review: Budget All-in-One Soundbar

Who Should Buy It

Key Specifications

Overview

The Hisense A620 2.1ch is a budget all-in-one soundbar aimed at buyers who want a simple upgrade over TV speakers without adding a separate subwoofer. The product listing positions it as a 2024 model with a 2.1 channel configuration and a visually distinct built-in woofer. Its headline features include 240W of amplification, DTS Virtual:X, Dolby Digital Plus, Bluetooth 5.3, and Roku TV Ready control.

According to the published specification, the A620 uses an all-in-one cabinet that houses a 75 by 160 mm subwoofer behind transparent acrylic. This gives the soundbar a clear design hook while avoiding the need for an external bass module. The listing also describes EzPlay, which lets a compatible Hisense TV remote control both the TV and the soundbar and shows soundbar settings on the TV menu.

Sound Quality

On paper, the A620 2.1ch relies on its built-in subwoofer and DTS Virtual:X processing to broaden the soundstage beyond a basic stereo bar. The 2.1 channel layout means two main channels share duties with the integrated woofer, which should provide more low-end presence than typical TV speakers. The published 240W figure suggests enough output for small to medium rooms, though the exact driver composition is not stated in the listing.

Dolby Digital Plus support is a useful inclusion for streaming and broadcast content, and it often carries a more efficient multichannel signal than standard Dolby Digital. DTS Virtual:X then attempts to create the illusion of height and side surround effects from the available drivers. Buyers report that this processing can widen the sound, but it is not the same as having dedicated surround speakers or upfiring height channels.

Because the listing does not publish full-range driver sizes or the frequency response, the sound quality can only be judged in broad terms. The combination of a small built-in woofer and virtual processing is common in this budget tier. It should improve dialogue clarity and add some punch, but it will not deliver reference-grade dynamics or deep sub bass.

Surround, Atmos and Audio Formats

The A620 2.1ch supports Dolby Digital Plus and DTS Virtual:X as its primary surround formats. DTS Virtual:X is designed to take a 2.1 or multichannel signal and simulate a taller, wider soundfield without physical surround speakers. This can help action scenes and atmospheric content feel less boxed in compared with plain stereo playback.

Dolby Atmos is handled in an indirect way on this model. The listing states that entry level soundbars are not capable of producing Dolby Atmos sound, but many Hisense TVs can decode Atmos. With the Hisense TV mode and an HDMI ARC or eARC connection, the TV can decode Atmos and send a downmixed or compatible signal to the soundbar. This means the A620 is not a native Atmos decoder and does not have upfiring height drivers.

For buyers with a compatible Hisense TV, this TV mode may still provide a useful pseudo Atmos experience. For everyone else, the soundbar falls back to Dolby Digital Plus and DTS Virtual:X. If native Atmos playback is a priority, a different model with dedicated decoding and height channels would be a better fit.

Subwoofer and Bass

The most distinctive hardware feature of the A620 2.1ch is its built-in subwoofer, which the listing describes as a 75 by 160 mm woofer behind transparent acrylic. This clear window lets you see the woofer vibrate with bass, adding visual interest to an otherwise basic soundbar design. The integrated approach means there is no separate subwoofer box to place in the room.

Bass performance will likely be modest because the woofer is housed inside the soundbar cabinet and measures just 75 by 160 mm. It should fill in low midrange and upper bass, but it will not match the depth of a dedicated powered subwoofer. The listing does not publish a frequency response or maximum SPL, so buyers should keep expectations realistic for a budget all-in-one design.

• Built-in 75 by 160 mm woofer
• Transparent acrylic window shows woofer movement
• No separate subwoofer box required
• Limited low frequency extension expected at this size
• Placement on a TV stand can affect bass response

Connectivity and TV Setup

The A620 2.1ch includes HDMI ARC, AUX, and USB inputs, according to the listing. HDMI ARC is the primary TV connection for sending audio from the television to the soundbar, and it also enables volume control over a single cable. The listing mentions eARC in the context of Hisense TV mode for Atmos passthrough, but the title lists HDMI ARC rather than eARC as the standard input.

Bluetooth 5.3 is the only wireless audio streaming option. There is no mention of Wi-Fi, Apple AirPlay, Chromecast, or any network based multiroom system. Roku TV Ready support means the soundbar can be recognized by a Roku TV and controlled through that interface, which may simplify setup for Roku TV users.

Physical setup should be straightforward since it is a single bar with no external subwoofer. You connect the HDMI cable to the TV ARC port, plug in power, and pair Bluetooth devices if desired. The listing does not specify what cables are included, so you may need to provide your own HDMI cable.

Features, Apps and Voice Control

The A620 2.1ch does not list a companion mobile app or any voice assistant integration. The main convenience feature is EzPlay, which lets a compatible Hisense TV remote control the soundbar and displays soundbar settings in the TV menu. This reduces the need for a separate remote when using a matching Hisense TV.

Roku TV Ready is another control feature, though it primarily affects setup and on-screen integration with Roku TV products. Without Wi-Fi, there is no app for room correction, EQ adjustment, or firmware updates through a phone. The listing also does not mention whether a basic remote is included, so the presumption is that most users will rely on HDMI CEC and the TV remote.

Design and Fit Under a TV

The A620 2.1ch has an all-in-one black cabinet with a transparent acrylic section that reveals the built-in subwoofer. The visible woofer is a design element that sets it apart from many plain budget soundbars. The listing says the HS series soundbars were made to integrate beautifully with Hisense TVs, which suggests a visual match with those sets.

The listing does not publish the dimensions or weight of the soundbar, so fit under a specific TV cannot be confirmed from the provided data. Based on the category and the all-in-one design, it is likely a compact bar that fits in front of most smaller TV stands. Buyers with tight clearance under a TV should check the physical measurements from another source before purchasing.

Who Should Buy It

This soundbar is best for budget-conscious buyers who want a simple 2.1 channel upgrade without a separate subwoofer. Hisense TV owners will get the most benefit from EzPlay and the TV mode for Atmos passthrough. It is also a reasonable choice for small bedrooms or secondary rooms where a full surround system is unnecessary.

Roku TV users may appreciate the Roku TV Ready recognition, and Bluetooth 5.3 makes it easy to stream music from a phone. The A620 is not intended for home theater enthusiasts who want true immersive surround sound or deep bass. It fits buyers who value a clean setup and a visible subwoofer design over maximum audio performance.

Alternatives Worth Considering

In the budget tier, the Vizio V-Series and Sony HT-S400 compete with the Hisense A620 2.1ch. Some Vizio models offer a separate wireless subwoofer, which can deliver stronger low bass than an all-in-one bar. The Sony HT-S400 also uses a separate subwoofer and includes Bluetooth, though its feature set is similarly basic.

Stepping up to the Samsung HW-Q600C or Polk Signa S4 brings a dedicated subwoofer and often more refined sound tuning. The Samsung option adds support for more immersive formats and a wider soundstage. The Polk Signa S4 is known for a simple setup with a wireless subwoofer and clear dialogue performance.

For a more premium compact option, the Sonos Beam Gen 2 and Bose Smart Soundbar 600 offer Wi-Fi streaming, app control, and voice assistant support. These models do not include a separate subwoofer, but they deliver more sophisticated processing and room correction. They sit in a higher price tier and lack the visible built-in woofer design of the Hisense.

Verdict

The Hisense A620 2.1ch is a respectable budget all-in-one soundbar for shoppers who want a fuss-free upgrade. Its 240W rating, visible built-in subwoofer, and DTS Virtual:X processing give it a clear on-paper appeal. EzPlay and Roku TV Ready add control convenience, especially for Hisense and Roku TV owners.

The main weaknesses are its indirect Atmos support, unpublished driver details, and lack of a separate subwoofer. These limits are expected at the budget tier but mean the A620 is not a true surround sound solution. If you need stronger bass or native Atmos, you should consider a step-up model with a dedicated subwoofer.

For the right buyer, the Hisense A620 2.1ch offers good value as a simple, visually distinctive soundbar. It should make TV dialogue clearer and add some low-end energy without taking over the room. Just understand that it is a budget convenience product, not a high performance home theater piece.
