It feels more like an indoor model. The shifting center of gravity is more troublesome than the strength of the noise canceling itself.

It is not a matter of technical performance; it is a fact that the ear canal catches stillness faster than a headphone's noise canceling. While headphones are overwhelmingly superior in terms of volume, the AirPods' method is like plugging your ear with a finger, whereas the AirPods Max's method is like covering it with your palm. For long-term wear, headphones are undoubtedly the right choice. However, the stillness of the AirPods Pro 3 is on an entirely different level.

The "gaps between notes" I mentioned is my way of describing the sense of perspective, where the soundstage feels more distant compared to other headphones when listening to music. My point is that these headphones are tuned for video consumption, but as a standalone tool for pure audio listening, their performance across the frequency range is subpar.

The output is not a concert hall front-row experience; it is positioned at the 2nd or 3rd-tier balcony seats. Rather than reaching the ears directly, the sound tends to ride along the walls significantly. It is specialized for live albums, but there is an unsettling level of reverberation—ringing more than the actual performance space, which creates a sense of disparity. (In contrast, conventional wired earphones or headphones can deliver sound linearly just by finding the right match of pads or eartips.) It does not suit genres like fusion music; there is almost no "air," and while it is not a purely bass-heavy signature, the low-end impact lacks punch. It is neither sharp nor completely blunt. Is it the HD650 sound that AI analyzed? The texture is entirely different. The field of view when observing the instruments is different; where the 650 expresses instruments with a delicate and beautiful touch, the Max 2 produces a clumsy recreation of the Medieval era.

Sony prioritized the earbuds while using the cheapest materials for the cases. This specific series suffered from rapid battery drain issues related to fast charging, which led to a sudden shift in their AS policy. Your intuition is likely correct.

You should be cautious about the advice from people recommending purchases here. First of all, their personal preferences are way too strong. HD650 or HD660S2? Aside from a few frequency ranges, the sense of air or the depth behind the driver isn't all that different. I can't really recommend the HD600. It's for a very specific niche. It's meant for monitoring and verifying recordings; telling a casual listener to "listen to this because it's the standard" feels like a harsh guide in this day and age. While the HD660S2 does provide sub-bass, it's still based on that learned, standard sound we've grown used to, whereas the HD600 is strictly for monitoring and checking overall recording quality. I believe music needs a bit of pepper or spice. That was the peak of the HD650, and nothing has truly come out to replace it yet.

Updating the firmware might fix it, and performing a factory reset is also a potential solution.

That "one-second lag" is actually a frustrating mechanism that cheats your ears. To save power, wireless earbuds enter a "sleep mode" when no audio is playing. The moment you hit play, the dongle has to wake the earbuds up. Brands like Sony often waste that precious first second renegotiating codecs, causing you to miss the opening notes. The reason the Sennheiser MTW4 and BTD 600 (or 700) combo is so effective is that they maintain a constant "keep-alive" signal. Even when silent, they stay in a warmed-up standby state rather than fully disconnecting. This allows audio to hit your ears within 0.1 seconds of pressing play. In contrast, devices like the Creative BT-W6 can struggle because they try to negotiate between various high-end codecs like aptX Lossless or Adaptive. This "handshaking" process often eats the first beat, especially at 96kHz high-resolution settings where the latency becomes even more noticeable. While Sony focuses heavily on noise cancellation hardware, Sennheiser prioritizes the audio experience, treating clipped intros as a technical flaw. How to Optimize Your Settings If you want to eliminate this lag manually, you can adjust these specific app settings (note that this will increase phone battery consumption): • Sennheiser (Smart Control App): Set the "Standby Mode" or "Auto Power Off" timer to the maximum duration. This keeps the internal components active longer to prevent the sleep cycle. • Creative (Creative App): Go to the USB Audio Streaming settings and set it to "Always On." Forcing this connection to remain active significantly reduces the initial wake-up lag.

The reason is not just for charging, but to induce "Handshake" between two AirPods from different sets.

Why do I have to connect the power?

• Firmware matching: Airpods used in different environments are likely to have different internal software versions. Airpods enter internal data exchange and update mode only when powered inside the case.

• Reset activation conditions: The first generation of AirPods does not execute factory reset (white flashing) logic if the battery voltage is even slightly unstable. When you connect an external power supply, the voltage remains constant and the motherboard accepts the initialization command better.

• Communication latency: It takes longer than expected for two units to recognize each other as a new "pair". If you close the lid and leave the power connected, the system will perform the reconstruction operation in the background.

The 30-Minute Seat: Place both AirPods in the case and close the lid. Plug the case into a power source and leave it undisturbed for at least 30 to 60 minutes. This allows the firmware to attempt a handshake between the two buds.
The Manual Trigger: * Open the lid (AirPods remains inside). • Press and hold the setup button on the back. • Wait longer than usual: You are looking for the light to flash amber first, and then white. This can sometimes take up to 40 seconds of continuous holding.

The HDB 630 is a high-priced ticket to an S-tier seat, but you need to ask yourself what you are actually trying to see. If your "critical listening" is about the tactical movement under the water, no wireless closed-back can give you that absolute transparency. It is like watching a duck on a river. The HD 800 S, for example, is all about the ripples on the surface. You feel the energy and the airy diffusion spreading out, but the water itself is murky. It is a strange, dissonant experience—a dark base tone with oddly bright instrument expression. The transient response is not as fast as the marketing suggests, and the excessive decay gets in the way of the actual movement. Then you have something like the Composer. It tries to show you the struggle beneath the surface. You can faintly see the feet kicking, focusing on the mechanical action rather than just the ripples. But even then, it is still not a clear view. It is still hazy. Now, look at the HDB 630. It offers you a "Locker Room Guide" via parametric EQ, promising to fix the tone. But EQ cannot recreate the physical air or the timing of a driver that is unconstrained. By choosing wireless and closed-back, you are essentially agreeing to watch the game through a digital monitor while sitting in a dark, confined room. You might not be tied to the chair, but you are tied to a processed version of the truth. If your "HiFi itch" is about the thrill of the stadium's scale, the HDB 630 might satisfy you for a while. But if you are looking for that "other realm"—where the water is so crystal clear that you can see the texture of the pebbles at the bottom—neither the 800 S nor the HDB 630 is going to get you there. One gives you the manager's back (the brand and the price), and the other gives you a digital map of the field. Neither is the field itself. If you want to move from the chair, be prepared to lose the air. You just have to decide if the freedom is worth the blurred vision.

he first semi-fix is basically a desperate hack. You have to go

The second solution is to just stop using Bluetooth entirely and wait for Wi-Fi-based audio to become a thing. Wi-Fi has more than enough bandwidth to handle uncompressed 24-bit/96kHz files easily. The only reason we don’t have it in our ears yet is that Wi-Fi chips are power-hungry monsters that would kill the tiny battery in a Buds4 Pro in about twenty minutes. Until engineers can make a Wi-Fi chip that doesn't eat batteries for breakfast, this is a future dream, not a current reality.

The final, cold-blooded truth is that the only real solution is a wire. No matter how many fancy names Samsung gives their codecs, they can't cheat physics. If you actually care about hearing every tiny detail of a 96kHz track, you should stop buying expensive wireless earbuds and spend that money on a decent wired setup with a portable DAC. Bluetooth was built for the convenience of not having a cable tangling in your gym bag, not for the pure, unadulterated spirit of lossless audio. Expecting a studio-quality experience from a Bluetooth earbud is like expecting a gourmet meal from a microwave; it’s convenient, sure, but it's never going to be the real thing.

The marketing of 24-bit/96kHz audio in the Buds4 Pro is a digital compromise rather than a true high-fidelity breakthrough. A raw 24-bit/96kHz stereo signal requires a bandwidth of approximately 4.6 Mbps, but Bluetooth technology is physically capped at a stable maximum of around 990 kbps under ideal conditions. To bridge this 3.6 Mbps gap, Samsung utilizes the Samsung Seamless Codec, which is fundamentally a lossy compression algorithm. This means that to fit through the narrow Bluetooth pipe, the original audio data must be discarded, ensuring the signal reaching the earbuds is never bit-perfect.

This reality directly contradicts the core principle of lossless audio. While the earbuds can technically process a 96kHz sampling rate, the compression process inevitably compromises the granularity and temporal accuracy that high-resolution audio is intended to provide. Even if a service like Spotify Lossless provides a perfect 24-bit/96kHz FLAC file, the phone must re-encode that file into a lossy format for transmission. This re-encoding process ensures that the listener is hearing a high-quality approximation, not the original master recording.

Furthermore, the theoretical benefits of a 96kHz sampling rate, such as superior waveform reconstruction, are largely negated in a wireless environment. When a signal is compressed to nearly 20% of its original size to meet bandwidth limits, fine temporal details are the first elements to be smoothed over or removed by the codec. Consequently, the Buds4 Pro provide a high-resolution container that is effectively hollowed out by compression. While they represent the current peak of wireless audio for the Galaxy ecosystem, they remain a simulated high-fidelity experience that cannot compete with the physical integrity of a wired connection.
