If you want to turn any TV into a dual-headphone shared-listening station with a screen that tells you what's happening, choose 1Mii DS70; if you need an all-in-one wireless gaming headset with a mic, 50-hour battery and 7.1 surround, choose EKSA E900BT. These two products share the word "Bluetooth" and almost nothing else. One is an audio transmitter that sits between your TV and your headphones. The other is the headphones. Deciding between them is really about deciding what problem you're solving.
• 1Mii DS70 — biggest strength: It pipes TV audio to two Bluetooth headphones or speakers at once, with an LCD screen and optical/RCA/AUX inputs plus aptX Adaptive, aptX LL and aptX HD support.
• 1Mii DS70 — biggest trade-off: It makes no sound on its own. No drivers, no earcups, no mic for calls — it's a bridge, not a headset.
• EKSA E900BT — biggest strength: A complete over-ear wireless gaming headset: 50mm dual-chamber drivers, 7.1 surround, 20 ms latency, 50-hour battery and a retractable ENC mic.
• EKSA E900BT — biggest trade-off: It's a single-user device. One wearer, one pair of earcups — no way to share the same audio with a second person.
• Who the DS70 is for: Households with a wired-only TV and one or two pairs of Bluetooth headphones already lying around.
• Who the E900BT is for: A gamer or movie watcher who wants one self-contained wireless headset for PC, PS5, PS4, Switch, laptop or phone.
The DS70 is a problem-solver for a very specific annoyance: your TV has optical, RCA and 3.5mm AUX outputs, but no Bluetooth, and you want to listen wirelessly. Plug the transmitter in, pick your input, pair your headphones, and the TV audio lands in your ears instead of the room. That alone is the core job, and the DS70 does it with a built-in LCD screen showing connection status, input mode and pairing info — genuinely useful when you're standing in front of a TV cabinet trying to remember which input you selected.
What sets it apart is the dual Bluetooth connection. Two headphones or speakers can run at the same time, which is the feature that makes late-night TV watching a shared activity instead of a solo one. Two people, two volume preferences, one TV. The 2-channel stereo output and "stereo surround sound" configuration mean it's built for straightforward TV and movie audio rather than positional gaming cues.
One feature worth flagging because it's easy to misread: there's a microphone input, and the description is clear that it collects sound but does not output it. It's for integrating voice or external audio, not for turning the DS70 into a speakerphone.
Buy the DS70 if you have a TV without Bluetooth, you already own wireless headphones, and you want two people listening at once. Skip it if you need actual headphones, want a mic for chat, or expect it to work with a phone as a normal Bluetooth audio device — it's a transmitter, not a receiver.
EKSA E900BT: Who It's For
The E900BT is the opposite kind of product: everything is inside the box. Over-ear, black, plastic enclosure, 50mm dynamic drivers arranged in EKSA's "dual chamber" design that the spec sheet says coordinates high, mid and low frequencies to reduce distortion. Whether or not you buy the marketing language, a 50mm driver is a large one, and large drivers generally move more air and produce fuller low end than small ones. That's spec-based reasoning, not a listening claim.
For gaming, the headline numbers are 20 ms latency and 7.1 surround sound. Twenty milliseconds is the kind of delay you won't notice in a game — footsteps and gunshots land when they should. Combined with the surround processing and the dual-chamber drivers, this is clearly aimed at people who want positional audio without a wired tether. Connectivity covers PC, PS5, PS4, Switch, laptop, mobile and Mac via 2.4 GHz USB and Type-C, with Bluetooth 5 as the wireless fallback and a 3.5mm jack as a wired option. That's a wide net for one headset.
The 50-hour battery is the number that will matter most day to day. A two-hour charge for fifty hours of playback is a genuinely low-maintenance ratio — charge it on a Sunday and mostly forget about it. For anyone who has owned a headset that dies mid-session, that's the selling point.
Comfort is addressed with CloudSoft ear cushions and breathable zero-pressure memory foam, and the mic is retractable with ENC (environmental noise cancellation) for clearer voice pickup. A retractable mic is a smart choice for a headset that's also meant for mobile use — out when you're on a call, tucked away when you're on a train.
Side-by-Side: Which Should You Choose?
• Best for shared TV listening → 1Mii DS70. Two Bluetooth headphones or speakers at once. The E900BT can only serve one wearer.
• Best for gaming → EKSA E900BT. 7.1 surround, 20 ms latency, 50mm drivers and console/PC connectivity are built for it.
• Best for battery life → EKSA E900BT. 50 hours on a 2-hour charge versus a transmitter that runs off USB power.
• Best for using headphones you already own → 1Mii DS70. It's designed to pair with your existing Bluetooth headphones.
• Best for voice chat and calls → EKSA E900BT. Retractable ENC mic. The DS70's mic input collects audio but doesn't output it.
• Best for older TVs with optical, RCA or AUX only → 1Mii DS70. Those three inputs are exactly what it's built around.
• Best for a single all-in-one purchase → EKSA E900BT. Headphones, mic and cable connectivity in one box.
• Best for on-screen status and setup clarity → 1Mii DS70. The LCD shows connection status and input mode — handy for households where several people use the same TV.
In my opinion, these aren't competitors so much as two answers to different questions, and I'd pick based on the question you're actually asking. If your TV is the problem — no Bluetooth, and you want two people listening wirelessly — I'd buy the 1Mii DS70, because nothing in the E900BT's spec sheet solves that. If you want one headset for gaming, calls and everything else, I'd buy the EKSA E900BT, because the DS70 makes no sound at all. My honest lean: for most people reading this, a headset is the more immediately useful purchase, so the E900BT is the safer default — but only if you don't already own headphones you love.
The EKSA E900BT. It's built for gaming, with 7.1 surround sound, 20 ms ultra-low latency, 50mm dual-chamber drivers and 2.4 GHz USB/Type-C connectivity for PC, PS5 and PS4. The DS70 is an audio transmitter with no gaming features.
No. The DS70 is a Bluetooth transmitter only — you pair it with your own Bluetooth headphones or speakers. The box includes a 3.5mm audio cable, a 3.5mm female-to-RCA cable, an optical audio cable, a USB power cable and a USB power adapter. The EKSA E900BT, by contrast, is the headset itself.
No. The E900BT is a single over-ear headset for one wearer. If sharing TV audio between two people is your goal, the 1Mii DS70's dual Bluetooth connection is the feature you want.
The EKSA E900BT, clearly. It has a retractable mic with ENC for voice calls and chat. The DS70 has a microphone input that collects sound but does not output it, so it isn't a calling device. If you need to be heard, the E900BT is the one.
