CLS uses the Burmester sound system. Burmester experience: High resolution and clarity. Even when using Bluetooth, the clarity is good. The clarity brings a certain sense of layering. Some tracks have excessive bass, which can feel overwhelming. Therefore, when selecting "Live Audio," do not set the center point between the front seats, or it will feel like the speakers are right next to your ears. The 3D effect is decent—not highly accurate but comfortable and not overwhelming.

As a CLS owner, I must say the audio configuration depends on the specific model. The base version comes with Mercedes' own sound system, featuring 8 speakers, which is sufficient for daily radio or pop music listening. However, the high-end version is equipped with Burmester, boasting over 13 speakers and a 590-watt amplifier. When I was choosing my car, I specifically compared them – the Burmester delivers thicker bass and noticeably clearer vocals, with surround sound effects even noticeable in the back seats. If your budget allows, I recommend going straight for the high-end version, as retrofitting the original audio system later is quite troublesome and requires rewiring. Now, when I play classical music during my commute, the layering of instruments is particularly strong, making even traffic jams less frustrating.

My friend's newly purchased CLS300 came with the Burmester sound system, and I was genuinely amazed during my test listen. The standard version comes with basic audio where the bass tends to get muddy, making electronic music sound flat. The Burmester system has speakers installed in the doors, dashboard, and even the ceiling, creating a much wider soundstage. Especially when playing lossless music via CarPlay, you can hear the granular texture of guitar strumming. The optional upgrade costs around 40,000 yuan, but considering you'll drive this car for ten years, it averages just over ten yuan more per day. When picking up the car, make sure to check the configuration sheet—don't let salespeople fool you into thinking it can be installed later. The factory audio system integrates with the central console and noise cancellation features, which aftermarket shops can't replicate perfectly.

If you're interested in the CLS, make an early decision about the audio system. The base model comes with standard audio, delivering average sound quality. The Burmester system is part of an optional package, which includes amplifier and upgrades. It's advisable to schedule a test drive before purchasing, focusing on comparing the two audio systems: play the same rock song and pay attention to whether the drum beats are crisp and if the vocals are overshadowed by the accompaniment. I've seen owners regret not opting for the upgrade later, as the CLS's excellent sound insulation actually highlights the shortcomings of the standard audio. Although the Burmester upgrade is more expensive, it also enhances the car's resale value. For daily drives lasting over three hours, a premium audio system significantly boosts happiness.

As a veteran driver who has owned three generations of CLS, let me talk about the audio system changes. The earliest model came with a basic sound system—just functional. The new base audio has improved significantly, but there's still a big gap compared to the Burmester system. The brilliance of Burmester lies in its acoustic lens technology, which prevents distortion even at maximum volume. During my test drive, I specifically sat in the back seat and noticed precise sound positioning—navigation prompts seemed to come from directly ahead. The upgrade costs 20,000 to 30,000 yuan, but considering the CLS's positioning as a luxury coupe, this audio system truly complements it. On the highway, activating surround mode delivers an immersive stereo experience that standard audio simply can't match. Remember, this option must be confirmed when ordering the car.

Young CLS owners should prioritize the audio system, as music is essential for commuting and workouts. The base audio lacks punch for hip-hop, but the Burmester system changes the game. Its dynamic response is lightning-fast, making bass lines in electronic music feel like punches to the chest, with 13 speakers vibrating in sync without interference. When I play music via from my phone, the system automatically compensates for the quality loss from wireless transmission. The upgrade cost spread over monthly payments is minimal, but the compliments from friends about the sound system are priceless. Playing live band recordings on weekend road trips creates a mobile concert hall experience—worth every penny.
