The catch
JBL Bar 300 MK2
More open stand width is needed for the 940 mm body. Its 50.5 mm height does nothing for a stand that is too narrow.
Side by side
JBL Bar 300MK2 vs AMBEO Mini: AMBEO saves width but needs open placement, JBL adds HDMI and optical
Quick verdict
JBL Bar 300MK2 is the pick if its 940 mm body fits and your ARC/eARC TV needs one extra HDMI source input for a compatible player, or if an older TV needs a direct optical connection. Its documented 4K passthrough is not a verified 4K120 or VRR route here. AMBEO Mini is the pick when its 700 mm width solves a fit problem on an open stand, the TV has ARC/eARC and enough inputs for all your sources, and you can leave at least 100 mm between bar and TV with clear sound paths and ventilation. Neither standalone box comes with physical rear speakers or a separate subwoofer.
Before you buy
Why, and what it costs you
A spare socket helps only when the source can use it
If the soundbar would take the TV’s last free HDMI socket, JBL can keep one compatible player connected through its own input, and Mini cannot take that player. You avoid a cable swap only if the player’s video works through JBL. Once the TV has enough suitable inputs, that practical advantage goes away. For 4K120 or VRR gaming, verify another route and don’t stretch the published 4K claim.
Where this comes from
In the manuals, the HDMI source input is a different thing from the ARC/eARC connection that receives TV audio. A TV return port does not add a player input.
The catch
Sennheiser AMBEO Soundbar Mini
Every player has to use the TV inputs and rely on its audio passthrough. An older TV has no direct optical fallback.
JBL Bar 300 MK2
- Why pick it
- Your ARC/eARC TV is missing one input, your player fits within JBL's documented 4K Dolby Vision or HDR10+ passthrough, and the 940 mm bar suits your open placement. Do not take for granted that this path handles 4K120 or VRR.
- Your TV has optical audio and no ARC/eARC, the 940 mm bar fits, and you are fine with buying an optical cable for basic TV audio with no Atmos promise.
- The catch
- More open stand width is needed for the 940 mm body. Its 50.5 mm height does nothing for a stand that is too narrow.
Sennheiser AMBEO Soundbar Mini
- Why pick it
- On your open stand the 700 mm Mini fits and the 940 mm JBL does not, with at least 100 mm of separation from the TV, clear sound paths and ventilation. Your TV has ARC/eARC, enough source inputs and the audio passthrough your content needs.

What this page compares
TV connections, cabinet fit and setup set JBL Bar 300MK2 and AMBEO Mini apart, along with limits that can change your choice.
Even a bar of the right size may leave you unplugging the streaming box, and one with the right ports may still cover the TV sensor. These two standalone bars trade a source connection for cabinet width, so start from your actual stand and whatever is already plugged in.
Which one fits
Pick the situations that sound like you
Hooking up the bar would push out one compatible 4K player
Provided the TV has ARC/eARC, the 940 mm body fits and the player works with JBL’s documented Dolby Vision or HDR10+ passthrough, JBL can accept that source. Do not treat it as a verified 4K120/VRR solution. With Mini, the player needs another suitable TV input.
- JBL Bar 300 MK2
- Better fit
- Sennheiser AMBEO Soundbar Mini
- Caution
An open stand that holds 700 mm but cannot take 940 mm
Even so, Mini needs at least 100 mm from the TV, clear sound paths and ventilation. Also check its 69 mm height and the clearance around the TV sensor. Your TV must offer ARC/eARC, enough source inputs and the audio passthrough you need.
- JBL Bar 300 MK2
- Not suitable
- Sennheiser AMBEO Soundbar Mini
- Better fit
Optical output is on the TV, but there is no ARC/eARC
JBL suits this direct wired connection as long as its 940 mm body fits and you buy the optical cable. This path promises no Atmos. Mini has no direct optical input, and an extractor falls outside this simple setup.
- JBL Bar 300 MK2
- Better fit
- Sennheiser AMBEO Soundbar Mini
- Not suitable
The eARC TV has enough suitable inputs and both bars have open room to fit
With the extra input and the narrower body, there is no longer a clear winner. Check the audio passthrough you require, remote operation and setup preferences. These specifications do not show better sound quality.

In practice
Differences you will notice
A spare socket helps only when the source can use it
If the soundbar would take the TV’s last free HDMI socket, JBL can keep one compatible player connected through its own input, and Mini cannot take that player. You avoid a cable swap only if the player’s video works through JBL. Once the TV has enough suitable inputs, that practical advantage goes away. For 4K120 or VRR gaming, verify another route and don’t stretch the published 4K claim.
How we worked this out
In the manuals, the HDMI source input is a different thing from the ARC/eARC connection that receives TV audio. A TV return port does not add a player input.
Mini takes less width but does not fix every clearance problem
Mini may be the better pick when an open stand holds a 700 mm bar but not a 940 mm one. Check its 69 mm height as well. Its manual also asks for at least 100 mm from the TV, ventilation and clear sound paths. Fitting the front opening does not make a tight cubby suitable. When both bars have a proper open position, width no longer decides the purchase.
How we worked this out
The size of the cabinet comes from its dimensions, and the space needed around it comes from the operating placement instructions.
An older TV may settle it ahead of any sound feature
For a TV with optical output and no ARC/eARC, JBL has a documented direct cable route. Budget for the optical cable and expect basic TV audio, with no Atmos promise. Mini lacks optical. Sennheiser mentions eARC extractors without formally recommending them, so don’t buy Mini on the assumption that a simple adapter will make the same setup work.
How we worked this out
The point here is a supported connection to the TV you already own. It does not predict which bar would sound better on a different TV.
Plug in your numbers
Is there room for the soundbar under your TV?
Measure the clear space under your TV. Count only the devices you will plug into the soundbar. Leave out the ones already connected to the TV. The numbers below are placeholders until you enter yours.
JBL Bar 300 MK2
Passes these checksIt measures 37 inches wide and 2 inches high, with 1 separate HDMI source input and 11.0 inches of total width to spare.
Sennheiser AMBEO Soundbar Mini
Fails these checksWith 0 separate HDMI source inputs, it cannot take the 1 device you want to plug into the bar.
Measure the top of an open shelf. This check does not cover enclosed cubbies. Detachable speakers count toward the docked width. Leave extra depth for cables and the TV stand. This checks size and port count only. Dolby Atmos, 4K/120Hz passthrough and the audio formats your TV supports are outside it.
Option A
JBL, Bar 300MK2
JBL Bar 300 MK2
This bar is 940 mm wide and 50.5 mm high, with one HDMI source input and optical audio. It can free up a TV input when the source fits its documented passthrough. Optional Cove speakers call for a matched pair, current firmware and JBL One setup.
- Best for
- Your ARC/eARC TV is missing one input, your player fits within JBL's documented 4K Dolby Vision or HDR10+ passthrough, and the 940 mm bar suits your open placement. Do not take for granted that this path handles 4K120 or VRR.
Facts we checked
- Connecting a player to the bar: One HDMI source input, plus the HDMI ARC/eARC TV connection
- Cabinet width, height and depth: 940 by 50.5 by 104 mm
- A TV with only optical audio output: Direct optical input, with a separately purchased cable
- Setup and room calibration: JBL One for Wi-Fi setup. Calibration can start from the remote
Option B
Sennheiser, AMBEO Soundbar Mini
Sennheiser AMBEO Soundbar Mini
This bar is 700 mm wide, and its wired TV connection is ARC/eARC. Leave at least 100 mm between it and the TV, and keep ventilation and sound paths clear. Players stay connected to the TV, and the TV has to pass along the audio formats they need.
- Best for
- On your open stand the 700 mm Mini fits and the 940 mm JBL does not, with at least 100 mm of separation from the TV, clear sound paths and ventilation. Your TV has ARC/eARC, enough source inputs and the audio passthrough your content needs.
Facts we checked
- Connecting a player to the bar: HDMI ARC/eARC TV connection only
- Cabinet width, height and depth: 700 by 69 by 101 mm including feet
- A TV with only optical audio output: No optical input
- Setup and room calibration: Smart Control or browser setup. Calibration can start on the bar
Spec by spec
Where they really differ
| Spec | JBL Bar 300 MK2 | Sennheiser AMBEO Soundbar Mini | In practice |
|---|---|---|---|
| Connecting a player to the bar | One HDMI source input, plus the HDMI ARC/eARC TV connection | HDMI ARC/eARC TV connection only | One compatible player can come off the TV input list with JBL. With Mini, every player stays connected to the TV. JBL documents 4K Dolby Vision and HDR10+, and no verified 4K120 or VRR path here. |
| Cabinet width, height and depth | 940 by 50.5 by 104 mm | 700 by 69 by 101 mm including feet | Mini is taller, though it saves 240 mm of width. The manual requires at least 100 mm of separation from the TV, ventilation and unobstructed sound paths. Measure those spaces before you call it a fit. |
| A TV with only optical audio output | Direct optical input, with a separately purchased cable | No optical input | For an older TV, JBL offers a simple wired route. The optical connection does not promise Dolby Atmos. Mini needs ARC/eARC for its supported wired connection. |
| Setup and room calibration | JBL One for Wi-Fi setup. Calibration can start from the remote | Smart Control or browser setup. Calibration can start on the bar | Don’t pick on the assumption that either calibration always requires a phone in hand. Network music and online updates have their own separate network requirements. |
| What the standalone package supplies | Soundbar, remote, HDMI cable and wall brackets | Soundbar, remote and HDMI cable. Wall mount is optional | Separate rear speakers and a separate subwoofer are in neither box. A virtual sound presentation does not count as physical speakers behind your sofa. |
| Optional system additions | Two Cove M1 or two Cove P1 speakers with current firmware and JBL One setup | Up to four wireless AMBEO Subs, bought separately | Each is a different addition to budget for and place. Don’t count the JBL matched pair or an AMBEO Sub as included, and don’t assume an arbitrary Bluetooth speaker is compatible. |
Trade-offs
What each pick costs you
With JBL Bar 300 MK2
- Several players cannot share one source input, and the primary sources here do not establish 4K120 or VRR passthrough.
With Sennheiser AMBEO Soundbar Mini
- Even the smaller width brings a 69 mm height, at least 100 mm of TV separation and open sound paths. The wall mount is its own separate accessory.
Change of plan
When the answer changes
Your ARC/eARC TV is one input short for a source verified compatible with JBL’s passthrough, and the 940 mm body has a suitable open spot
Go with JBL Bar 300 MK2. JBL can keep that player connected, but check its exact signal needs first. The documented 4K claim does not establish 4K120 or VRR.
Your ARC/eARC TV has enough source inputs, and only the 700 mm Mini fits your open stand along with 100 mm TV separation, ventilation and clear sound paths
Go with Sennheiser AMBEO Soundbar Mini. Mini gets around the width limit as long as the TV passes the audio your sources need and Mini’s 69 mm height does not block the screen or sensor.
You want a direct wired connection for basic TV audio, and your TV has optical audio but no ARC/eARC
Go with JBL Bar 300 MK2. JBL makes sense only if the 940 mm bar fits and you add an optical cable. Don’t expect Dolby Atmos over that optical route.
Your only placement is an enclosed shelf with blocked sound paths, or you need the package to include physical rears and a separate subwoofer
Neither model fits. Either change the placement or compare complete speaker packages. These constraints stay in place whatever the virtual channel label and however narrow the cabinet.
Decision guide
Before you buy
Sketch the cable route first, then measure the open placement. A spare input and a narrower cabinet address different problems.
What this page can’t tell you
- This comparison covers connections, placement and ownership. It does not rank measured dialogue clarity, bass output or surround realism.
- The primary JBL documents that were inspected establish 4K, Dolby Vision and HDR10+ passthrough, though not a complete refresh-rate or VRR matrix. Check any 4K120/VRR requirement separately before relying on its source input.
- No claims are made about prices, stock, seller, delivery dates or optional-accessory totals. Having the exact listing identity does not establish current availability.
