Main trade-off
JBL Bar 300 MK2
The 940 mm body needs more open stand width. Its 50.5 mm height does not solve a stand that is too narrow.
Head-to-head
JBL Bar 300MK2 vs AMBEO Mini: JBL adds HDMI and optical, AMBEO saves width but needs open placement
The short answer
Choose JBL Bar 300MK2 if its 940 mm body fits and your ARC/eARC TV needs one extra HDMI source input for a compatible player, or a direct optical connection for an older TV. Its documented 4K passthrough is not a verified 4K120 or VRR route here. Choose AMBEO Mini when its 700 mm width solves an open-stand fit problem, 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 supplies physical rear speakers or a separate subwoofer.
Before you choose
The reasoning and the trade-offs
An extra socket only helps if the source can use it
When the soundbar consumes the TV's last free HDMI socket, JBL can keep one compatible player connected through its own input. Mini cannot take that player. This avoids a cable swap only if the player's video works through JBL. With enough suitable TV inputs, that practical advantage disappears. For 4K120 or VRR gaming, verify another route rather than extending the published 4K claim.
What this is based on
The manuals distinguish the HDMI source input from the ARC/eARC connection that receives TV audio. A TV return port is not an extra player input.
Main trade-off
Sennheiser AMBEO Soundbar Mini
All players must use the TV inputs and depend on its audio passthrough. There is no direct optical fallback for an older TV.
JBL Bar 300 MK2
- Choose it for
- Your ARC/eARC TV is short one input, your player fits JBL's documented 4K Dolby Vision or HDR10+ passthrough, and the 940 mm bar fits your open placement. Do not assume that path supports 4K120 or VRR.
- Your TV has optical audio but no ARC/eARC, the 940 mm bar fits, and you accept buying an optical cable for basic TV audio without an Atmos promise.
- Main trade-off
- The 940 mm body needs more open stand width. Its 50.5 mm height does not solve a stand that is too narrow.
Sennheiser AMBEO Soundbar Mini
- Choose it for
- The 700 mm Mini fits your open stand where the 940 mm JBL does not, with at least 100 mm TV separation, clear sound paths and ventilation. Your TV has ARC/eARC, enough source inputs and the audio passthrough your content needs.
- Main trade-off
- All players must use the TV inputs and depend on its audio passthrough. There is no direct optical fallback for an older TV.
About this comparison
Compare JBL Bar 300MK2 and AMBEO Mini by TV connections, cabinet fit and setup, with the limits that can change your choice.
A bar can be the right size and still leave you unplugging the streaming box. It can have the right ports and still cover the TV sensor. These two standalone bars trade a source connection against cabinet width, so start with your actual stand and the devices already plugged in.
Winner by situation
Start with what you need it to do
Connecting the bar would displace one compatible 4K player
JBL can accept that source if the TV has ARC/eARC, its 940 mm body fits and the player works with its documented Dolby Vision or HDR10+ passthrough. This is not a verified 4K120/VRR solution. Mini needs another suitable TV input.
- JBL Bar 300 MK2
- Better fit
- Sennheiser AMBEO Soundbar Mini
- Caution
An open stand supports 700 mm but cannot accommodate 940 mm
Mini still needs at least 100 mm from the TV, clear sound paths and ventilation. Check its 69 mm height and TV sensor clearance. The TV must have ARC/eARC, enough source inputs and the audio passthrough you need.
- JBL Bar 300 MK2
- Not suitable
- Sennheiser AMBEO Soundbar Mini
- Better fit
The TV has optical output but no ARC/eARC
JBL fits this direct wired connection if its 940 mm body fits and you buy the optical cable. No Atmos is promised on this path. Mini has no direct optical input, and an extractor is outside this simple setup.
- JBL Bar 300 MK2
- Better fit
- Sennheiser AMBEO Soundbar Mini
- Not suitable
Both bars fit openly and the eARC TV has enough suitable inputs
The extra input and narrower body no longer create a clear winner. Check required audio passthrough, remote operation and setup preferences. These specifications do not establish better sound quality.

What matters in practice
The differences that matter
An extra socket only helps if the source can use it
When the soundbar consumes the TV's last free HDMI socket, JBL can keep one compatible player connected through its own input. Mini cannot take that player. This avoids a cable swap only if the player's video works through JBL. With enough suitable TV inputs, that practical advantage disappears. For 4K120 or VRR gaming, verify another route rather than extending the published 4K claim.
How we reached this conclusion
The manuals distinguish the HDMI source input from the ARC/eARC connection that receives TV audio. A TV return port is not an extra player input.
Mini saves width without solving every clearance problem
An open stand that can support a 700 mm bar but cannot accommodate 940 mm may favor Mini. Check its 69 mm height too. The manual also asks for at least 100 mm from the TV, ventilation and clear sound paths. A tight cubby is not made suitable by fitting the front opening. If both bars have a proper open position, width stops deciding the purchase.
How we reached this conclusion
Cabinet dimensions establish physical size. The operating placement instructions add the space needed around the cabinet.
An older TV can settle this before sound features do
If the TV has optical output but no ARC/eARC, JBL has a documented direct cable route. Budget for the optical cable and treat this as basic TV audio, without an Atmos promise. Mini lacks optical. Sennheiser mentions eARC extractors but does not formally recommend them, so do not buy Mini assuming a simple adapter will make the same setup work.
How we reached this conclusion
This is about a supported connection to the TV you already own. It does not predict which bar would sound better with a different TV.
Try your real numbers
Will the soundbar fit under your TV?
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
JBL Bar 300 MK2
Meets these checks37 inches wide and 2 inches high, with 1 separate HDMI source input. It leaves 11.0 inches of total spare width.
Sennheiser AMBEO Soundbar Mini
Does not meet these checks0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.
Choice A
JBL, Bar 300MK2
JBL Bar 300 MK2
A 940 mm wide, 50.5 mm high bar with one HDMI source input and optical audio. It can save a TV input when the source fits its documented passthrough. Optional Cove speakers require a matched pair, current firmware and JBL One setup.
- Best matched use
- Your ARC/eARC TV is short one input, your player fits JBL's documented 4K Dolby Vision or HDR10+ passthrough, and the 940 mm bar fits your open placement. Do not assume that path supports 4K120 or VRR.
Checked facts
- 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
Choice B
Sennheiser, AMBEO Soundbar Mini
Sennheiser AMBEO Soundbar Mini
A 700 mm wide bar whose wired TV connection is ARC/eARC. Keep at least 100 mm between it and the TV, with ventilation and clear sound paths. Players stay connected to the TV, which must pass their required audio formats.
- Best matched use
- The 700 mm Mini fits your open stand where the 940 mm JBL does not, with at least 100 mm TV separation, clear sound paths and ventilation. Your TV has ARC/eARC, enough source inputs and the audio passthrough your content needs.
Checked facts
- 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
Meaningful differences
What changes the fit
| What changes | JBL Bar 300 MK2 | Sennheiser AMBEO Soundbar Mini | Why it matters |
|---|---|---|---|
| Connecting a player to the bar | One HDMI source input, plus the HDMI ARC/eARC TV connection | HDMI ARC/eARC TV connection only | JBL can take one compatible player off the TV input list. Mini leaves every player connected to the TV. JBL documents 4K Dolby Vision and HDR10+, not a 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 saves 240 mm of width, but it is taller. Its manual calls for at least 100 mm separation from the TV, ventilation and unobstructed sound paths. Measure those spaces before calling it a fit. |
| A TV with only optical audio output | Direct optical input, with a separately purchased cable | No optical input | JBL offers a simple wired route for an older TV. That optical connection is not a promise of 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 | Do not choose by assuming either calibration always needs a phone in hand. Network music and online updates have separate network requirements. |
| What the standalone package supplies | Soundbar, remote, HDMI cable and wall brackets | Soundbar, remote and HDMI cable. Wall mount is optional | Neither box includes separate rear speakers or a separate subwoofer. The virtual sound presentation is not a count of 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 | These are different additions to budget and place. Do not count the JBL matched pair or an AMBEO Sub as included, or assume an arbitrary Bluetooth speaker is compatible. |
What you give up
Every choice has a cost
If you choose JBL Bar 300 MK2
- One source input is not a hub for several players, and the primary sources here do not establish 4K120 or VRR passthrough.
If you choose Sennheiser AMBEO Soundbar Mini
- The smaller width still comes with a 69 mm height, at least 100 mm TV separation and open sound paths. The wall mount is a separate accessory.
Recommendation switch
The decision flips if...
Your ARC/eARC TV needs one extra input for a source verified compatible with JBL's passthrough, and its 940 mm body has a suitable open placement
Choose JBL Bar 300 MK2. JBL can keep that player connected. Check its exact signal needs first. The documented 4K claim does not establish 4K120 or VRR.
Only the 700 mm Mini fits your open stand, with 100 mm TV separation, ventilation and clear sound paths, and your ARC/eARC TV has enough source inputs
Choose Sennheiser AMBEO Soundbar Mini. Mini solves the width limit, provided the TV passes the audio your sources need and its 69 mm height does not block the screen or sensor.
Your TV has optical audio but no ARC/eARC, and you want a direct wired connection for basic TV audio
Choose JBL Bar 300 MK2. Choose JBL only if the 940 mm bar fits and you include an optical cable. Do not expect that optical route to provide Dolby Atmos.
The only placement is an enclosed shelf with blocked sound paths, or the package must include physical rears and a separate subwoofer
Choose neither. Change the placement or compare complete speaker packages. A virtual channel label and a narrow cabinet do not remove these constraints.
What matters in practice
Before you choose
Draw the cable route, then measure the open placement. A spare input and a narrower cabinet solve different problems.
What this comparison cannot tell you
- This is a connection, placement and ownership comparison. It does not rank measured dialogue clarity, bass output or surround realism.
- The JBL primary documents inspected establish 4K, Dolby Vision and HDR10+ passthrough but not a complete refresh-rate or VRR matrix. A 4K120/VRR requirement must be checked separately before relying on its source input.
- Prices, stock, seller, delivery dates and optional-accessory totals are not asserted. Exact listing identity does not establish current availability.
