• Razer Base Station V2 — biggest strength: A built-in DAC with a 3.5mm combo port that drives 7.1 surround sound on a wired headset, plus two USB 3.1 charging ports, all in a tall aluminum stand with a non-slip base.
• Razer Base Station V2 — biggest trade-off: It is not a listening device. It makes no sound on its own, it needs a PC to be useful, and it takes up real desk space at roughly 11 inches tall and about a pound in weight.
• Piegricdiat Invisible Sleep Headphones — biggest strength: Bluetooth 5.3 with a 3D surround sound claim, an 8-hour battery life, IPX6 waterproofing, and a skin-soft silicone fit designed so side sleepers can wear them for hours.
• Piegricdiat Invisible Sleep Headphones — biggest trade-off: They are earbuds, not a surround processor. The "surround" effect is a stereo presentation from a single tiny driver per ear, not discrete multi-channel audio, and the 16-ohm impedance tells you they are tuned for easy phone driving, not critical listening.
• Who each pick is for: Razer for the PC gamer or desk worker who wants surround processing, charging, and a proper headset stand in one unit. Piegricdiat for the side sleeper, the swimmer, or anyone who wants music and calls without anything pressing on their ears.
The Base Station V2 is best understood as an audio hub disguised as a headset stand. The headliner is the built-in 7.1 surround sound DAC, routed through a single 3.5mm audio jack combo port. That matters because it means the surround processing happens in the stand, not in your headset. You plug a wired headset into the 3.5mm port, the DAC handles the audio, and you get virtual 7.1 surround from a standard stereo headset. If you have ever wanted a wider sense of direction in games without buying a new headset, this is the mechanism that gives it to you.
Who should buy it: PC players with a wired headset who want surround processing, a charging point, and a stand in one footprint. Who should skip it: anyone who listens on a phone or laptop only, anyone who wants an actual listening device, and anyone with a very shallow desk, because it is a tower with a 4.72-inch base diameter. It also needs a wired connection to your PC to do its main job, so a fully wireless setup is not the target here.
Piegricdiat Invisible Sleep Headphones: Who It's For
The Piegricdiat buds solve a different problem: how to listen in bed without pain. The design centers on proprietary skin-soft silicone eartips and eartip caps, and the fit is deliberately shallow — you do not push them into the ear canal. That is the whole point for side sleepers. If you roll onto your side, there is no hard shell pressing into your ear the way a normal earbud would. The brand claims you can wear them for long stretches without soreness, and the shape supports that logic.
The feature set is built for real-world sleep and movement. Bluetooth 5.3 gives you a stable, low-delay wireless connection to a phone, and the listed battery life is 8 hours of average use with a 1-hour charge time, which lines up with a full night. IPX6 waterproofing is a genuinely unusual inclusion: that rating covers deep water spray and supports swimming, surfing, and snorkeling, so these are buds you can take into water. There is also a sleep mode that disables the physical buttons entirely so you only control them from your phone — a smart touch if you thrash around at night and do not want to trigger playback by accident. A built-in noise reduction microphone handles calls, and the noise control is listed as sound isolation rather than active cancellation.
The surround sound angle here is worth being precise about. The specs mention 3D surround sound and a "whale cavity stereo surround sound" technology, alongside a 5.3 binaural chip. In practice this is a stereo pair of drivers creating a wide, immersive presentation — not discrete 7.1 channels. It sounds bigger than its size suggests, but it is a different thing from what the Razer stand does.
Side-by-Side: Which Should You Choose?
• Best for true surround sound processing → Razer Base Station V2. The 7.1 DAC over a 3.5mm port is real audio processing for a wired headset; the Piegricdiat's 3D surround is a stereo presentation from tiny drivers.
• Best for sleeping and side-sleeping comfort → Piegricdiat Invisible Sleep Headphones. Shallow skin-soft silicone tips and a sleep mode built for the bed, not the desk.
• Best for charging and desk organization → Razer Base Station V2. Two USB 3.1 charging ports plus a stand that keeps a large headset off your desk.
• Best for battery life and untethered use → Piegricdiat Invisible Sleep Headphones. 8 hours of average battery life and a 1-hour charge, with Bluetooth 5.3 freedom from cables.
• Best for water and workouts → Piegricdiat Invisible Sleep Headphones. IPX6 waterproofing supports swimming and surfing; the Razer stand is a desk-bound device.
• Best for PC gaming setups → Razer Base Station V2. Chroma RGB, aluminum construction, and a wired DAC pipeline match a desktop rig.
• Best for phone-first listeners → Piegricdiat Invisible Sleep Headphones. Bluetooth pairing to a smartphone is the core use case.
• Best for build feel → Razer Base Station V2. Aluminum and rubber construction with a detachable base, versus the Piegricdiat's plastic enclosure.
For surround sound in the sense of actual multi-channel processing, I would buy the Razer Base Station V2. In my opinion it is the only one of the two that delivers surround as a processing feature you can point at — a 7.1 DAC feeding a wired headset — and it doubles as a charging hub and a proper stand for a large headset. The Piegricdiat buds are excellent at what they are designed for, and if your priority is sleeping comfortably on your side or swimming with music, they are the pick, not the Razer. But if the question is surround sound headphones, the Razer is the more honest answer. Check the current price on Amazon before you commit, since both sit in very different budget tiers.
how to get surround sound headphones
Surround sound on headphones comes from processing, not from the headphones alone. With the Razer Base Station V2, the built-in 7.1 surround sound DAC does that processing, and you connect a wired headset to its 3.5mm combo port. The Piegricdiat buds instead rely on a stereo 3D surround presentation from their in-ear drivers.
how to test surround sound headphones
Pick a source with clear directional audio, like a game with positional sound, and listen for whether sounds move left, right, and behind you rather than sitting flat in the center. The Razer stand's 7.1 DAC is the piece doing the work, so the effect depends on your headset and the source. The Piegricdiat's 3D effect is easier to notice with music and movies than with positional game audio.
how to make surround sound headphones
You cannot convert plain stereo headphones into true surround with software tricks alone — you need processing somewhere in the chain. The Razer Base Station V2 puts that processing in the stand through its 7.1 DAC. The Piegricdiat buds deliver an immersive stereo image via their binaural chip, but that is a different result from discrete channels.
The Piegricdiat Invisible Sleep Headphones, clearly. Their skin-soft silicone tips sit shallow in the ear, so side sleeping does not press a hard shell into your ear, and sleep mode disables the buttons so you do not trigger playback while you move. The Razer Base Station V2 is a stand that holds headphones on a desk — it is not something you wear in bed at all.
