I can’t present four products as headphones when two are a mixer and a microphone. I’ll give an accurate guide based on the supplied facts, clearly separating the two actual headphone options from the unrelated gear.
For guitar amp, the Superlux HD661 is my pick among these products: its closed-back design, two cable lengths, and included adapter suit a straightforward wired setup. The blue HD661 is the runner-up, with the same listed core headphone specifications.
• Superlux HD661 — best for a direct wired headphone setup; pick this if you want a closed-back design, 3.5 mm connection, and a 6.3 mm adapter.
• Superlux HD661 — best for the same monitoring use in the blue variation; pick this if its listed 40 mm driver, 68-ohm impedance, and cable options suit your setup.
• Douk Audio Mini — best for combining several audio sources; pick this if you need a four-input mixer, not a pair of headphones.
• FEELWORLD PM1 — best for computer recording and streaming; pick this if you need a microphone with USB-C and XLR outputs, not guitar-amp headphones.
The Superlux HD661 is the clearest fit here for someone looking for studio headphones for guitar amp. It is a wired, closed-back, over-ear model with a 40 mm dynamic driver and a listed frequency range of 10 Hz to 20 kHz. Its enclosed design is intended to help limit outside sound, which can be useful when playing or monitoring in a room where other noise competes for attention.
The practical details are strong for a simple setup. It comes with a 1 m cable and a longer 3 m cable, plus a 3.5 mm-to-6.3 mm adapter. The shorter lead may be easier to manage when you are close to your equipment; the longer one offers more reach. The adapter gives you a way to connect to a compatible 6.3 mm headphone socket without buying that connector separately.
Its 68-ohm impedance and 102 dB sensitivity are useful specifications to check against your amp’s headphone output. They do not, on their own, guarantee a particular loudness or sound quality with every device, so confirm that the output is intended for headphones and can drive the load. The supplied facts do not establish a wireless listening option, so I would treat this as a wired choice.

This second listing is also the Superlux HD661, presented as a blue variation. The core listed headphone specifications match the other HD661: a closed-back design, a 40 mm dynamic driver, 10 Hz–20 kHz frequency range, 68-ohm impedance, and 102 dB sensitivity. For guitar-amp monitoring, the decision is therefore less about a different audio design and more about whether this variation is the one you want to consider.
Its listed accessories are also the same: 1 m and 3 m cables, a cable clip, a carrying pouch, and a 3.5 mm-to-6.3 mm conversion plug. That makes it adaptable to nearby or more distant listening positions and to equipment with either of those headphone-jack sizes. As with the other version, check your amp’s output specification rather than assuming every headphone socket will behave identically.
The product description positions the enclosed design for monitoring in places with more surrounding noise. In everyday use, that makes the HD661 a sensible style of headphone for concentrating on your own playing without choosing an open-back design. It remains a wired model in the useful sense that the listed accessories are cables; the data does not establish Bluetooth use as a working feature.
The trade-off is essentially the same as for the first listing: there is no stated microphone or specific guitar-amp compatibility claim. The headphone specifications can help you assess fit, but they cannot tell you how a particular amp will sound through it. In my opinion, consider this variation if you want the HD661’s listed setup and prefer this version’s identifying color; there is no basis here to claim a different sound from the first HD661.
The Douk Audio Mini is not a headphone. It is a compact four-channel line mixer, so it belongs in a different part of a recording or monitoring setup. It has four groups of 3.5 mm inputs, an AUX output, and a 3.5 mm headphone jack. That could be relevant if you want to combine signals from multiple compatible sources, but it is not a substitute for headphones to connect to a guitar amp.
The distinction between its two operating modes matters. In active mode, it needs independent USB power; its built-in amplifier can then boost the mixed signal, and the headphone jack can be used for direct monitoring. In passive mode, it needs no power, but the signal is attenuated and the headphone jack does not support direct headphone monitoring according to the supplied details. You would need to add a headphone amplifier for that use.
Four separate input-volume controls let you adjust the source levels independently, while a main output knob controls the overall output. That layout could help when balancing multiple line-level sources. The listed use cases include instruments and playback devices, but the information does not specify a guitar-amplifier speaker output or confirm that the mixer is designed to connect to one. Do not treat it as a device for connecting between an amp’s speaker output and headphones.
Its main trade-off for this guide is simple: it adds routing and mixing options, but it is not a headphone product. I would consider it only if you have several suitable audio sources to combine and understand whether you need active USB power or a separate headphone amp. For solo practice, the HD661 is the more directly relevant item in this group.
The FEELWORLD PM1 is a dynamic microphone, not a headphone. It is designed for recording and streaming, with USB-C and XLR outputs, a cardioid pickup pattern, and a 3.5 mm headphone jack for monitoring. The included package information lists a boom arm, a mounting bracket, and a 2 m USB/Type-C cable; an XLR cable is not listed as included.
This could make sense for someone recording guitar or speaking into a computer, but it serves a different job from headphones connected to an amp. Its headphone jack is for monitoring the microphone signal; the available details do not say that it takes an amp’s headphone output or that it can replace a guitar-amp headphone connection. Its listed frequency-response information describes the microphone, not a pair of listening headphones.
The connection mode changes which controls are available. In USB mode, the microphone has a tap-to-mute control and volume adjustment, along with real-time headphone monitoring. In XLR mode, the listed mute, volume, RGB-light, and headphone-monitoring functions are unavailable. That difference is worth considering if you plan to use it with an audio interface or mixer rather than a computer.
The trade-off is that the PM1 contributes no headphone drivers or cable choice for listening to an amp. I would consider it for computer-based recording or streaming, not when shopping for studio headphones for guitar amp. It also should not be confused with travel or laptop earbuds: searches such as “best headphone for flights” or “best wireless clip on earbuds for laptop” describe separate needs that this microphone does not address.
How We Picked
I compared the listed connection options, headphone specifications, included accessories, and intended functions.
The order is my independent editorial judgment based on fit for guitar-amp headphone use; no brand paid for placement.
Both Superlux HD661 listings are headphones. The Douk Audio Mini is a mixer, and the FEELWORLD PM1 is a microphone with a headphone-monitoring jack.
The HD661 includes a 3.5 mm connection and a 6.3 mm adapter. Check your amp’s headphone output and its guidance for compatible headphones before connecting; the supplied details do not confirm compatibility with every amp.
Both list the same core driver, frequency range, impedance, sensitivity, and cable accessories. They are identified as different color variations, and the supplied information does not establish a sound difference between them.
