How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a headset that turns games, movies and PC audio into a wide 7.1 surround-sound stage with a 120-hour battery and a boom mic, choose EKSA 2.4GHz; if you need earbuds that disappear into your ears so you can sleep on your side, hide them at work and even swim with them, choose Piegricdiat Invisible Sleep Headphones.
• EKSA 2.4GHz biggest strength: true wireless freedom with a 2.4GHz USB dongle, Bluetooth 5.3 and a 3.5mm cable, plus 7.1 surround sound from 50mm dynamic drivers.
• EKSA 2.4GHz biggest trade-off: it is an over-ear gaming headset, so it is bulky, visible and not something you can lie on your side with.
• Piegricdiat biggest strength: a genuinely tiny in-ear design built for side sleepers, with skin-soft silicone tips, a sleep mode that locks the buttons and IPX6 waterproofing.
• Piegricdiat biggest trade-off: 8 hours of battery per charge and sound isolation instead of active noise cancellation, so it is a personal listening tool rather than a gaming rig.
• Who EKSA is for: gamers, PC users, movie watchers and anyone who wants one headset for console, phone and computer.
• Who Piegricdiat is for: side sleepers, light sleepers, people who want near-invisible earbuds at work, and swimmers.
The EKSA 2.4GHz headset (model E1000BT) is built around one idea: give you a proper surround-sound experience without locking you to a single device. The 50mm dynamic drivers cover a 20Hz–20,000Hz range, and the headline feature is 7.1 surround sound — the kind of processing that spreads audio around your head so footsteps, engines and dialogue land in distinct places instead of a flat stereo line. For gaming and films, that spatial width is the whole point.
Connectivity is where it earns its place. You get a 2.4GHz USB-A dongle for low-latency wireless (EKSA lists 20ms), Bluetooth 5.3 for phones and tablets with roughly 10 metres of range, and a 3.5mm jack as a wired fallback for anything that refuses to cooperate. That triple-mode setup means one headset covers a PS5, a Switch, a laptop, a phone and an older controller. The ENC microphone is there for voice chat and calls, and the 120-hour battery life is the kind of figure that means you charge it occasionally rather than nightly.
The build is over-ear with oval memory-foam earcups, wrapped in ABS, aluminium and PU, in a black-and-silver finish with RGB lighting and push-button controls. In my opinion this is a desk-and-couch headset: great for long sessions, less great if you want to lie down. If you sleep on your side, wear glasses under tight cups, or need something invisible in an office, this is the wrong shape for you — that is exactly the gap the Piegricdiat fills. It also ships with a USB dongle, a Type-C cable, a manual, a quick setup card and safety instructions, and it carries a 2-year warranty.
The Piegricdiat Invisible Sleep Headphones (model Q26S) attack a completely different problem. These are tiny in-ear buds designed to sit discreetly in your ear — the brand calls them "invisible" — so you can wear them at work without anyone noticing, or in bed without a plastic shell digging into your pillow. The skin-soft silicone eartips and caps are the reason side sleepers are the target audience: toss and turn all you like, the design is meant to avoid the pressure that normal earbuds create.
There is a genuinely thoughtful detail here: a sleep mode that disables every button on the buds, so a stray touch while you roll over does not skip a track or hang up on someone. In that mode you control everything from your phone. Battery life is listed at 8 hours of continuous use with a 1-hour charge time, and the Bluetooth 5.3 binaural chip gives you a stable, low-delay connection to a phone.
On audio, Piegricdiat leans on "whale cavity stereo surround sound" and a 16-ohm impedance, which tells you these are easy to drive from a phone. There is a built-in noise-reduction microphone for calls, and noise control is handled by sound isolation rather than active cancellation. The IPX6 rating is unusually generous for sleep buds — it covers swimming, surfing and snorkelling, so a shower or a pool session is fair game. The trade-off is scope: no dongle, no wired option, no boom mic, and 8 hours means a daily charge if you use them all day. If you want one device for console gaming, look at the EKSA instead.
• Best for surround sound while gaming or watching films → EKSA 2.4GHz. The 7.1 surround processing and 50mm drivers are built for spatial audio.
• Best for side sleeping and lying down → Piegricdiat. Slim in-ear shells plus silicone tips and a button-locking sleep mode.
• Best battery life → EKSA 2.4GHz. 120 hours versus 8 hours per charge.
• Best for water and workouts → Piegricdiat. IPX6 waterproofing supports swimming and watersports; the EKSA sheet lists no water rating.
• Best for multiple devices → EKSA 2.4GHz. 2.4GHz dongle, Bluetooth 5.3 and 3.5mm wired in one headset, versus Bluetooth only on the Piegricdiat.
• Best for calls and voice chat → EKSA 2.4GHz. An ENC boom-style mic and a full headset fit beat a tiny in-ear mic for long conversations.
• Best for discretion at work → Piegricdiat. Near-invisible buds you can wear without drawing attention.
• Best for comfort over a full day in the ear canal → Piegricdiat. The design avoids deep insertion, which is the main cause of sore ears with normal buds.
If I had to pick one, I would buy the EKSA 2.4GHz — but only because my priority would be surround sound, latency and battery life across a console, PC and phone. It is the more capable all-rounder, and the 2.4GHz dongle plus 7.1 processing is the combination that actually delivers the surround-sound experience this comparison is about. That said, if your real problem is "I cannot sleep on my side with earbuds in," the Piegricdiat solves a problem the EKSA cannot even attempt. Two different jobs, two different answers — pick the job you actually have.
how to get surround sound headphones
Surround sound is a feature of the headset, not something you download. The EKSA 2.4GHz lists 7.1 surround sound built in, so you get it by connecting the headset — ideally via the 2.4GHz USB dongle — and enabling the surround option in your console or PC audio settings. The Piegricdiat instead describes "whale cavity stereo surround sound" for music listening on a phone.
how to test surround sound headphones
Play something with clear directional cues — a game with footsteps or a film with movement across the screen — and listen for whether sounds travel around you rather than sitting in a flat left-right line. On the EKSA 2.4GHz you can A/B this by switching between the 2.4GHz dongle, Bluetooth and the 3.5mm cable to hear how the processing changes. The Piegricdiat has no wired mode, so any comparison there is Bluetooth versus Bluetooth.
how to make surround sound headphones
You cannot convert a pair of ordinary earbuds into surround headphones; it is a hardware and processing feature baked into the product. The EKSA 2.4GHz already includes 7.1 surround sound with 50mm dynamic drivers, so the work is done for you. Sleep buds like the Piegricdiat are designed for discreet stereo listening, not for virtual surround.
how to fix surround sound headphones
Start with the connection: reseat the 2.4GHz USB dongle, or try the 3.5mm cable, since a partial connection is the usual culprit for one-sided or flat audio. Then check that surround is actually enabled in your device's audio menu rather than defaulting to plain stereo. If it still sounds wrong, the EKSA's 2-year warranty is the next step — but note the Piegricdiat does not offer surround processing to fix in the first place.
