Does the headset have a wired input jack?

Yes.

The headset offers two wired connection options: a 3.5mm analog jack for analog input; and a USB-C port for lossless digital input.

Which connection method works best for headphones: wired or wireless?

The headphone's signal path architecture is designed to provide a superior listening experience regardless of whether it's wired or wireless.

While sound quality does depend on the quality of the input signal, even lower-quality audio signals can benefit from the same optimization processing as high-quality sources. In our experience, the improvement is more significant with lower-quality signals because they have more room for improvement. With a wireless connection, the tube preamplifier effectively improves the relatively lower sound quality of Bluetooth signals, making the sound warmer and more natural.

When listening to high-quality audio sources via the 3.5mm analog jack or USB-C lossless digital input, the built-in tube preamplifier and dual mono amplifiers work together to fully preserve the integrity of the original signal, revealing all its details and textures.

Will the vacuum tube burn out and need to be replaced?

Very unlikely, absolutely not.

Under continuous use, the expected lifespan exceeds 30,000 hours.

Do vacuum tubes get hot?

No.

The new generation of vacuum tubes used in headphones (Nutube 6P1) operate at low temperatures and do not generate excessive heat like traditional vacuum tubes.
