The Beo4 Remote Control — MK1 to MK5 Explained
Which Version Do You Have, and Which Do You Need?
The Beo4 is one of the most iconic remote controls ever made. But not all Beo4s are the same — understanding the differences matters when buying or replacing one.
The Bang & Olufsen Beo4 remote control was in production from 1996 to around 2016 in various forms, serving as the primary interface for the majority of B&O systems made during that period. Its elegant single-column button layout, satisfying tactile buttons, and beautiful aluminium-finish design made it one of the most distinctive remote controls in consumer electronics history.
However, several distinct versions were produced over the years, with differences in button layout, programmability, and compatibility that matter considerably if you're buying one for a specific system. Here's what you need to know.
Beo4 (Original)
The original Beo4 introduced the characteristic single-column button layout with the illuminated display panel. Uses two AAA batteries. Compatible with all MasterLink-capable B&O products from the period. The MK1 can be identified by its slightly different button feel and the absence of later programming features. Less common than later versions and increasingly sought after for its originality.
Beo4 MK2
The MK2 introduced improved button responsiveness and a revised internal circuit. The external appearance is near-identical to the MK1, making visual identification difficult without close inspection of the label on the back. Introduced the ability to control a wider range of source options including Decoder (for TV set-top boxes), and offered more flexible source programming. The most commonly encountered version on the pre-owned market.
Beo4 MK3
The MK3 brought expanded programmability — allowing the remote to control a greater number of source types and improving compatibility with the then-new generation of B&O products. Key improvement was support for controlling BeoVision televisions with richer functionality. The display panel on the MK3 is generally considered more reliable than the MK1/2. Still a very practical, fully functional remote for most classic B&O systems.
Beo4 Type 1928
The final and most capable version of the Beo4. The MK4 introduced a revised button layout with some function changes, improved battery life, and the ability to control an expanded range of B&O products including BeoLink-capable systems from the 2010s era. The backlit display is brighter and more legible. Compatible with most B&O products that support IR (infrared) remote control up to this period. The most versatile Beo4 for use with mixed-era B&O setups.
The easiest identification method is the sticker on the back of the remote, which includes the B&O part number. The Type number printed on the label corresponds to the product generation. If the label is worn, MK1/MK2 remotes tend to have a slightly softer button feel; MK3/MK4 have firmer, more positive button action.

For classic B&O systems — BeoSound 9000, BeoCenter 2, BeoVision televisions up to approximately 2014 — the Beo4 remains the correct and most compatible remote. For modern B&O systems on the Mozart platform (BeoSound Stage, BeoLab 28, current range), the BeoRemote One is the appropriate choice and offers significantly expanded functionality.
When purchasing a pre-owned Beo4, check the following: the battery compartment for corrosion (common if batteries were left inside for extended periods); the display for dead segments or faded illumination; button responsiveness across all keys (the List/Go and volume keys see most use); and the condition of the label on the reverse, which identifies the version.
For a classic B&O system, any MK2–MK4 Beo4 in good condition is the right choice.
The Beo4 is one of the most satisfying remote controls ever made — a genuinely pleasant object to use daily. BeoVerse regularly stocks tested pre-owned Beo4 remotes across all versions, with condition clearly described and battery compartments inspected before sale.
