Notebook Desktop Long Bluetooth Extra Bass Speaker 2.1 Channel 31.5cm

This notebook desktop long Bluetooth extra bass speaker is a 2.1 channel computer soundbar with a 31.5 x 5.5 x 6cm overall size. It is designed for computer use and is available in four variants: E-1002D wired with no Bluetooth, E-3511 wired Bluetooth, E-3541 wireless Bluetooth version (rechargeable), and the new E-3557 wireless Bluetooth version (rechargeable). Operation is by button, input voltage is 220V, and impedance is 70. The long, slim shape is suited to sitting beneath or in front of a notebook or desktop monitor. If you need a wired-only connection, the E-1002D is the non-Bluetooth option. If you want wireless Bluetooth, the E-3541 and E-3557 are rechargeable, while the E-3511 is wired Bluetooth. No battery capacity is stated for the rechargeable versions. This is a practical computer speaker for everyday desktop audio.

Features and Construction

The speaker is built around a 2.1 channel configuration and a 70 impedance rating. It uses button operation and a 220V input voltage. The four colour variants differ mainly by connection type and Bluetooth availability rather than by size, because all share the same 31.5 x 5.5 x 6cm overall dimensions. The long format is intended for computer setups where a wider soundbar fits more naturally than a pair of small satellite speakers.

Material and Build

The source text does not list specific materials for this speaker. What is known is its electronic and physical format: 2.1 channels, 70 impedance, 220V input voltage, and button controls. The product is supplied as a speaker plus packaging. Because no material data is provided, no claims are made about the outer casing or internal components beyond the stated specifications. The four model names indicate the connection and power differences: E-1002D is wired without Bluetooth, E-3511 is wired Bluetooth, and E-3541 and E-3557 are wireless Bluetooth rechargeable versions.

Size and Practical Fit

The overall size is 31.5 x 5.5 x 6cm. That long, low profile is designed to sit on a desk, typically under or in front of a computer monitor, without taking up the same footprint as separate bookshelf speakers. The 31.5cm width is the main differentiator, giving a soundbar-style shape for notebook and desktop computer use. There are no other measurements in the source text, so height and depth remain as stated: 5.5cm and 6cm respectively. The speaker is not described as portable, and no weight is provided.

Uses and Placement

This speaker is intended for computer use, which covers notebook and desktop setups in home, study, or office environments. The connection method depends on the variant chosen. The wired E-1002D requires a wired connection only. The E-3511 adds wired Bluetooth. The E-3541 and E-3557 are wireless Bluetooth rechargeable versions. Because it is a 2.1 channel speaker, it is positioned as a single long unit rather than a multi-piece surround system.

Event or Professional Use

For desk-based work, online meetings, or general computer audio, the long 31.5cm speaker can sit below a monitor and provide a single-unit alternative to separate speakers. Button operation keeps controls simple when switching between tasks. Because the source text does not state power output, frequency response, or compatibility with specific software, those details should not be assumed. What is clear is the 2.1 channel layout, 70 impedance, and 220V input voltage.

Everyday Home Use

At home, the speaker can be used with a notebook or desktop computer for music, video, and general listening. The wireless Bluetooth rechargeable versions, E-3541 and E-3557, remove the need for a permanent audio cable, while the E-1002D and E-3511 rely on wired connections or wired Bluetooth. The 31.5 x 5.5 x 6cm size makes it a long, slim unit that can sit on a desk without dominating the space. No remote control, app control, or additional accessories are listed in the source text.

Benefits and Buying Value

The main buying decision is connection type. If Bluetooth is not needed, the E-1002D is the wired-only option. If Bluetooth is wanted, the E-3511 is wired Bluetooth, while E-3541 and E-3557 are wireless Bluetooth rechargeable versions. All four share the same 2.1 channel, 70 impedance, 220V input voltage, button operation, and 31.5 x 5.5 x 6cm size. The long shape is the practical advantage for computer desks. There is no stated battery capacity, no stated power rating, and no price or savings information in the source text.

Reuse and Low Maintenance

The rechargeable wireless versions, E-3541 and E-3557, can be recharged rather than relying on disposable batteries, but no battery capacity or runtime is given. The wired E-1002D and wired Bluetooth E-3511 use a wired connection. Maintenance guidance is limited to keeping the unit clean and using the button controls as intended; no specialist care instructions are provided in the source text. The package contains the speaker and packaging only, so no cables, adapters, or remote are confirmed unless they are part of the standard packaging.

Why Choose This Product

Choose this speaker if you want a long 31.5cm computer soundbar with a 2.1 channel layout and a choice of wired or Bluetooth models. The four variants cover no-Bluetooth wired, wired Bluetooth, and two rechargeable wireless Bluetooth options. The 70 impedance and 220V input voltage are stated, and the button operation keeps control simple. Because the source data is limited to these specifications, the product is best matched to buyers who need a straightforward desktop speaker rather than advanced features that are not documented.
