Headphone Amplifier 8 Channel, Stereo Headphone Amp with 9 Pcs 6.35mm to 3.5mm Jack (STABCL S-800)
Quick take
The STABCL S-800 is an 8-channel stereo headphone amplifier and audio splitter that lets you feed one input into multiple headphone outputs, with individual volume control per channel. Main caveats to watch include adapter compatibility for certain headset-style plugs and an audible plug-in “pop” reported by a buyer.
Pros and cons
Pros
- 8 output channels with independent volume control per channel (useful for multiple listeners).
- Mono/stereo switch for quick mix-checking workflows.
- Metal, CNC-unibody style construction and a compact form factor for desk portability.
- Works as a multi-output audio distributor, not just a headphone amp.
Cons
- Some buyers report a loud popping sound when plugging in headphones, even when a channel volume is set low.
- Included jack adapters may not work as expected with certain 3-ring headset plugs.
- Not positioned as a hi-fi or audiophile-grade amp, so expectations should match a studio monitoring tool.
What buyers think
Buyer-review evidence points to a clear theme: this is a practical, everyday multi-output monitoring solution. Several comments highlight low-noise operation, workable volume control, and usefulness for adding more headphone outputs (and even distributing a line signal to multiple speakers or devices) when your source only has one headphone out. The build quality and compact, metal chassis are also recurring positives, especially for desk setups with limited space. At the same time, review detail is limited overall, but there are meaningful fit-related concerns, including an audible pop at plug-in time and adapter behavior with certain headphone plug types.
How it works for real setups
This unit combines two roles in one chassis: a multi-channel headphone amp and a simple audio splitter/distributor. You send an input signal into the box, then use up to eight output channels to feed headphones (or other compatible monitoring gear). The key practical feature is that each channel includes its own volume knob, so you can accommodate different listening levels without touching the source.
Key features that matter when you are choosing
8 channels with independent volume
If you regularly have multiple listeners, a vocalist, a producer, or a band on headphones, independent volume control is the difference between “everyone hears the same level” and “everyone can hear comfortably.” The split design is also convenient for studio and stage workflows where you want consistent signal routing without constant cable swapping.
Mono/stereo switch for monitoring and mix checks
The mono/stereo mode switch is designed for flexibility while listening. When you are checking balance, phasing, or compatibility, being able to quickly change the listening mode can help you catch issues before export or final playback.
Input and connector compatibility (and the adapter reality)
The amp supports 6.35 mm (1/4 inch) and 3.5 mm (1/8 inch) TS and TRS-style connections. It also ships with multiple 6.35 mm to 3.5 mm adapter pieces. That means it is likely to cover common studio headphone jacks, but compatibility can vary with headset-style “3-ring” plug designs, so it is worth double-checking your specific headphone and plug type before relying on the included adapters.
Pros and cons in plain English
When this is a smart buy
- You need more headphone outputs than your audio interface or mixer provides.
- You want independent volume control per listener, without using multiple headphone splitters.
- You are working in a studio, rehearsal, or stage environment where a metal, compact box is helpful.
- You want mono/stereo monitoring capability for quick checks during sessions.
When you should look elsewhere
- Your setup uses headset-style 3-ring plugs and you cannot confirm the adapters will behave correctly.
- You are sensitive to plug-in behavior noise (some buyers report a loud “pop” when connecting).
- You are shopping strictly for high-end, audiophile listening performance, where expectations may need to shift toward more specialized headphone amplifiers.
Price and availability
The STABCL S-800 is typically sold as an affordable multi-output headphone amplifier option, and pricing can vary. If you are comparing value against other headphone splitters or lower-channel amps, focus on what you actually need: the number of simultaneous headphone feeds and whether per-channel volume is essential for your workflow.
Verdict
The STABCL S-800 is a solid choice for multi-listener monitoring and basic studio routing, especially because it combines eight outputs, independent volume control, and mono/stereo switching in a compact metal enclosure. Just be sure your headphone plug types match the supported TS/TRS formats, and account for the possibility of plug-in “pop” behavior if you routinely connect or disconnect headphones during a session.
FAQ
Does this headphone amp have independent volume control for each output?
Yes. Each of the eight output channels includes its own volume control, so you can set listening levels independently.
Can it be used as an audio splitter, or only for headphones?
It can also be used as an audio distributor with one input feeding multiple outputs, with independent channel volume control.
Is it compatible with 3.5 mm headphone plugs?
It supports 3.5 mm (1/8 inch) connections, and it includes multiple 6.35 mm to 3.5 mm adapter pieces. If you use a headset-style “3-ring” plug, compatibility may depend on the adapter and plug design.
Does it support mono and stereo monitoring?
Yes. There is a mono/stereo switch for listening mode flexibility.
Will it work with my studio setup if I only have one headphone output?
That is one of the most common use cases. The 8-channel design is meant to add more headphone feeds from a single output source.
Are there any downsides to know before buying?
Some buyers report an audible popping sound when plugging in headphones. Also, a subset of plug and adapter types may not behave as expected, so confirm your connector and adapter fit before relying on it for a session.
