How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the most immersive, detail-rich soundstage for mobile gaming and music at home, choose SENDYAUDIO Apollo Open-Back Planar; if you need wireless freedom, active noise cancelling and all-day battery for mobile gaming on the move, choose Sennheiser ACCENTUM True.
• SENDYAUDIO Apollo — biggest strength: a 68mm planar magnetic driver in a wood over-ear housing, tuned for a wide, transparent, detailed soundstage with deep bass and natural vocals.
• SENDYAUDIO Apollo — biggest trade-off: it is fully wired (2.5mm x 2), has no noise cancelling at all, and its open-back design leaks sound both ways.
• Sennheiser ACCENTUM True — biggest strength: hybrid active noise cancellation, Bluetooth 5.3 wireless freedom and up to 28 hours of total playtime with the charging case.
• Sennheiser ACCENTUM True — biggest trade-off: it is an in-ear earbud with a dynamic driver, so it cannot match the physical scale and open presentation of a full-size planar over-ear.
• Choose the Apollo if you game and listen at a desk or couch and care most about pure sound quality.
• Choose the ACCENTUM True if you game on a phone or handheld anywhere — on the bus, on a plane, in a noisy room — and want ANC plus wireless convenience.
The Apollo is, first and foremost, a sound-quality play. SENDYAUDIO built it around a 68mm planar magnetic diaphragm, and the company says that driver took more than three years of experimentation to get the magnetic circuit and magnetic distance right so the resonance balances out. That is the kind of engineering language you hear around planar headphones specifically, and it matters for gaming: a big planar diaphragm with high internal damping in the composite material is exactly the recipe for the fast, clean, well-separated presentation that helps you pick out footsteps, distant gunfire and directional cues without the sound turning muddy when a lot is happening on screen. The claimed frequency range runs from 20Hz to 40KHz, so there is plenty of low-end extension for explosions and rumble, and the treble is described as bright with clear detail rather than rolled off.
Buy the Apollo if you want the best headset for mobile gaming in the sense of pure audio fidelity, and you play at a desk where you can plug in and where a little sound leakage in and out of the open cups is fine. Skip it if you game on a commute, on a plane, or in a shared room, or if you need wireless, ANC or a pocketable case. Open-back, wired, no noise cancelling — that is a deliberate design, not a flaw, but it rules out a lot of mobile use.
Sennheiser ACCENTUM True: Who It's For
The ACCENTUM True is the opposite philosophy: take the sound with you and shut the world out. It is a true wireless in-ear earbud with hybrid active noise cancellation, so you can block out a noisy train, a busy café or a loud household and stay locked into your game. When you need to hear someone, transparent mode pipes the outside back in without pulling the buds out. That combination — ANC plus transparency — is genuinely useful for mobile gaming, because you can go fully immersed in a ranked match and then flick to transparency when someone talks to you.
The specs back up the all-day angle. Sennheiser rates 8 hours of playtime in the buds and another 20 hours in the charging case, for up to 28 hours total, with both Qi wireless and USB-C charging. The case is pocket-sized and white, matching the white silicone buds. Connectivity is Bluetooth 5.3 with Bluetooth LE and Auracast support, a 10-metre range, and dual-mic technology for clear voice chat — which is exactly what you want for multiplayer voice comms on a phone or handheld. Sound comes from Sennheiser's TrueResponse dynamic driver, and the Smart Control app gives you a 5-band EQ and presets so you can push bass for shooters or lift the highs for detail. You get four ear tip sizes, and the fit was developed from in-ear ergonomic research, which is the difference between buds that stay put during a tense match and buds that fall out.
Buy the ACCENTUM True if you want multipoint-friendly wireless earbuds for mobile gaming on the go, if you take calls and voice chat often, or if you need noise cancelling to concentrate. Skip it if you mainly listen critically at a desk and want the scale, openness and wired purity of a full-size planar over-ear — no earbud, however good, presents sound the way an open-back 68mm planar does.
• Best sound quality and soundstage → SENDYAUDIO Apollo Open-Back Planar. A 68mm planar magnetic driver in an open-back wood housing simply moves more air and separates instruments better than an in-ear dynamic driver.
• Best for mobile gaming on the move → Sennheiser ACCENTUM True. Bluetooth 5.3, no cable, a pocket case and hybrid ANC are built for gaming away from your desk.
• Best for battery life → Sennheiser ACCENTUM True. 8 hours in the buds plus 20 in the case, with Qi wireless and USB-C charging.
• Best for noise cancelling → Sennheiser ACCENTUM True. The Apollo has no noise control at all and is open-back, so it lets sound in and out.
• Best for voice chat and calls → Sennheiser ACCENTUM True. Dual-mic technology and touch controls for audio and calls; the Apollo lists only a cable remote.
• Best for long desk sessions without fatigue → SENDYAUDIO Apollo. The ergonomic, lightweight headband and over-ear fit are designed for hours of wear without pressure.
• Best for plug-in-and-forget simplicity → SENDYAUDIO Apollo. A 6N OCC braided cable with a spring relief and no battery to charge.
• Best for wireless convenience and portability → Sennheiser ACCENTUM True. Four ear tip sizes, a pocket-sized case, and a fit tuned for secure wear.
For mobile gaming specifically, I would buy the Sennheiser ACCENTUM True. Wireless, ANC, transparency mode, dual mics, 28 hours of total battery and a pocket case make it the more usable tool when you're gaming on a phone or handheld rather than sitting at a desk. In my opinion it is the better all-rounder for that job. That said, if your "mobile gaming" is really a couch or desk setup and you want the best possible sound, I'd take the SENDYAUDIO Apollo Open-Back Planar — its 68mm planar driver and open-back presentation are on another level for immersion, as long as you accept the wire and the lack of noise cancelling.
It depends on where you play. For gaming away from a desk — on a phone, on transit, in a noisy room — the Sennheiser ACCENTUM True wins with Bluetooth 5.3, hybrid ANC and 28 hours of total battery. For pure sound quality at a desk, the wired, open-back Apollo with its 68mm planar driver is the stronger pick, in my opinion.
Yes. They use hybrid active noise cancellation to block out surroundings, and there's a transparency mode so you can hear what's going on around you without removing the earbuds. The SENDYAUDIO Apollo has no noise control at all — it's an open-back wired headphone.
No. It's a wired over-ear headphone with a 2.5mm x 2 connection and a 6N OCC braided cable, plus a remote on the cable. There's no Bluetooth, no battery and no charging case, so it's a stay-put headphone rather than a take-anywhere one.
I don't quote prices here because they change often — check the current price on Amazon using the button on this page before deciding. On features alone, the ACCENTUM True gives you more technology per dollar (ANC, wireless, mics, case), while the Apollo puts its budget into driver and materials. Value depends on whether you want convenience or fidelity.
