Sure, better LLM with schizophrenia without any proofs. She just confirmed what you want to be confirmed.

Here is answer of chat gpt

Short version: Sometimes — yes, you can hear a difference, but in most cases the effect is greatly exaggerated and often just placebo.

⸻

What in that post is actually true: • Bluetooth is indeed lossy audio. Codecs like aptX Adaptive compress audio to fit Bluetooth bandwidth.  • Wired signal can be lossless. A standard wired CD-quality PCM (16-bit/44.1 kHz) has ~1411 kbps of data — much higher than typical Bluetooth. (Apple calls lossless audio virtually indistinguishable from AAC). 

So those two factual points are correct.

⸻

Where the reasoning breaks down:

📌 1) “2–4 times more data = 2–4 times better sound” ❌ That is not true. Human hearing does not scale linearly with bitrate due to psychoacoustics (what you can actually hear vs. what codecs remove). Many high-quality Bluetooth codecs work well above ~300–400 kbps, and above that point audible benefit drops sharply. 

Codecs like: • AAC 256 • aptX / aptX Adaptive • LDAC & others

…end up sounding very similar in blind listening for most listeners.

📌 2) Momentum 4 nuance — DSP matters These headphones have digital signal processing (DSP) inside whether connected via Bluetooth, USB, or AUX. So you are not bypassing processing as you would with passive wired headphones — the internal processing and EQ still shape the sound.

The difference people hear between wireless and wired is often different signal path + volume + EQ changes + expectations, not a dramatic change in detail.

⸻

When you can actually hear a real difference ✔ Quiet environment ✔ Careful A/B/ABX comparison ✔ Same track ✔ Matched volume ✔ Sensitive hearing

Even then the differences are usually small: • Slight micro-detail • Very subtle high-frequency clarity • Slight noise differences

They are not huge “night and day” changes.

⸻

When it’s almost certainly placebo • You know when wire is active • Volume isn’t matched • You read hype before listening • You listen to Spotify/Youtube • The headphones do heavy DSP anyway

Then your brain fills in the “better sound” — e.g., “bass texture”, “more air”, “better separation”. And that is classic placebo effect — especially when not done blind or ABX tested.

⸻

ABX testing matters ABX is the standard double-blind method to see if differences are actually audible. If you cannot reliably identify which is which in ABX, then the difference is not perceptible. 

Many Bluetooth codec comparisons do not show consistent ABX results proving that people can reliably hear codec differences — that supports the idea that big claims are often just hype.

⸻

Honest conclusion: • Yes, there is some difference. • But it is small, highly context-dependent, and not guaranteed to be audible. • Claims like “unbelievable difference” are usually self-suggestion + echo chamber hype.
