I bought it on Black Friday 2023. After about 10 days connected to a Samsung QE65QN90AA TV, I have the following to say:

This is a very special product aimed at very few people. Given that it is the most powerful and capable soundbar without additional speakers and subwoofer – for this money you could get a proper "ready" 5.1 Dolby Atmos system with many speakers and achieve better surround, but not better sound quality. Definitely better than the Samsung, LG, and Sonos Arc options that cost around 1000 euros (I haven't heard the Ambeo Plus). It is exactly what you would expect from a high-quality Sennheiser product in terms of materials and clarity of sound and bass. I don't think Sennheiser should release small speakers to complement the average surround result of the soundbar – as other companies have done, because I believe the Ambeo Max achieves what it tries: maximum quality in a "small" one-speaker package. The seriousness of the company's purpose is reflected in the special microphone included for calibration.

HOWEVER. For its price and what it offers, I have the following to say:
- DTS:X in 10-channel sound from Blu-ray is fantastic.
- Atmos from 5.1 or 7.1 from Blu-ray or downloaded movies is OK.
- YouTube and other music streaming services like Tidal do not have multichannel sound but the Ambeo profiles do a very good job of adding volume and dimension to the sound.
- And here is the big issue: if you only play Netflix etc. streaming, then there is no point in getting such a good soundbar because you are not using it to its fullest (usually everything is Atmos 5.1 channels). If you don't give it the best possible Atmos or DTS signal, then it's simply not worth the money. The Ambeo Plus or Sonos Arc would be more than enough for this job.

Still, the Ambeo Max is a unique product because there is nothing else that achieves better at this price.
- Will you get another cheaper soundbar? You will lose sound quality.
- Will you add satellite speakers to the soundbar (reaching the price of the Ambeo Max)? You will have better surround but not as good sound quality again.
- Will you get an amplifier with 2 speakers at this price? You may have a better soundstage, but you will lose (even the average) Dolby Atmos and DTS and the capabilities of an AVR (Tidal streaming, Airplay, etc.)
- Will you get an AVR amplifier (e.g. Denon x2800h) with 2 speakers at this price? You won't achieve anything better and you'll be tempted to add more speakers to your small living room!

Edit after 2 months of daily use:
- Depending on the recording and mixing of Atmos in each series/movie, voices are not heard that well at low volume (below 15%) and often music and effects drown out the dialogues (mainly because the voices are heard almost only from the center speaker and everything else plays on all the speakers, I believe). I have tried all options and Ambeo profiles. If you turn up the volume a bit, this problem does not exist. There is no problem in DTS or PCM.
- Sometimes slight "cracks" and "pops" are heard from the speakers only in Atmos, rarely, but it happens. I changed the HDMI cable and the frequency of the problem decreased.
- I am impressed by the soundbar's performance in music playback, really very good even from YouTube.

Edit August 2025...
After a firmware and software update released by the company, ALL negative/annoying issues have been resolved. Crystal clear voice everywhere thanks to new sound processing even at very low volume, no trace of popping and crackling for days now, now the little screen and the small "on" white light turn off after a while and don't blind you... literally no negatives anymore and I'm raising my rating to 5 stars.

Amazing solution. Truly exceptional experience, it changes the way you watch movies and play video games. If you have the right room, you feel like you have speakers placed behind you and on the ceiling!
I am mainly talking about the Dolby ATMOS option.
Since my TV does not support ATMOS and DTS, I connected my laptop directly to the Soundbar with HDMI 2.1 and from there with a regular HDMI 2 it goes to the TV's ARC (Samsung Q6FN55 2018). This way, the audio signal does not get downgraded! Crystal clear sound with clarity in the dialogues. Be careful, you can only change the EQ from the mobile App (which in iOS you need at least iOS 13 - it doesn't work on iPhone 6).

Well, I live in England and I live in a big room.
I didn't have space for speakers behind me, let alone on the ceiling.
It's heavy and bulky, but when you place it somewhat correctly in the room (around the center and at ear level), you add the microphone they give you to automatically adjust the sound... okay, you don't believe it... it's not for all budgets and all living rooms.
I can recommend the Sonos Arc and someone can gradually add speakers.
