• Delton 50X biggest strength: 35 hours of talk time and 40 hours of playtime, plus a charging dock and USB dongle that suit a fixed desk setup.
• Delton 50X biggest trade-off: It's a monaural (single-ear) over-ear design with sound isolation rather than active environmental noise cancellation, so it's built for calls more than immersive listening.
• oleap Noise Cancelling Headphones biggest strength: 50dB ENC call noise reduction with VoiceOn tech, a one-touch mute button, and Bluetooth 5.3 rated for up to 15 meters.
• oleap Noise Cancelling Headphones biggest trade-off: 10 hours of call time and 16 hours of playback per charge — a fraction of the Delton's runtime — though a 10-minute top-up gives 2 hours of use.
• Choose Delton 50X if you live on back-to-back meetings and hate charging.
• Choose oleap Noise Cancelling Headphones if you work in genuinely noisy spaces and need your voice to cut through.
The Delton 50X is built around one idea: stay on calls all day without babysitting a battery. Delton rates it at 35 hours of talk time and 40 hours of playtime, which is the standout number in this comparison. A full charge takes about 2 hours, and you can charge the headset directly or drop it on the included dock. That dock matters more than it sounds — it gives the 50X a permanent home on a desk, so it's topped up and ready whenever a call starts.
For call clarity, Delton leans on DSP and ENC (Environmental Noise Cancellation) to filter ambient sound and push your voice forward. It's a monaural design — one over-ear earcup with a microphone boom that rotates 270 degrees, so you can position the mic where your mouth actually is. The headband adjusts, the ear cushion is plush, and the head cushion softens long sessions. A 30mm dynamic driver and a 20Hz–20,000Hz frequency range cover speech and casual music fine.
Buy it if you're a professional parked at a desk or moving between a home office and a work one, and your priority is never running out of juice mid-meeting. Skip it if you want active noise cancellation for music, stereo sound, or a headset for loud open-plan chaos — the 50X isolates sound rather than cancelling it, and it's single-ear by design.
oleap Noise Cancelling Headphones: Who It's For
The oleap headset attacks the opposite problem: making your voice intelligible when everything around you is loud. Its headline feature is VoiceOn, oleap's call noise cancellation tech, rated at 50dB of noise reduction and claimed to cut out 99% of ambient noise while improving average MOS sound quality scores. That's specifically about the microphone path — office chatter, household noise, road noise — which is exactly what call center agents, hotline staff and remote workers fighting background chaos care about.
The hardware backs that up in a few practical ways. Bluetooth 5.3 pushes the range to 15 meters with better wall and door penetration, plus multi-device switching for a PC, phone or tablet. The controls include a one-touch mute button that instantly cuts your mic, which is a genuinely useful privacy feature when you need to say something to someone in the room without leaving the call. The open-ear design uses a dipole structure with three tuning holes to minimize sound leakage at high volume.
Audio is handled by a 16.2mm dynamic driver per side with BassLeap bass enhancement, and oleap rates output up to 105dB at 105dB sensitivity and 20 ohm impedance. Battery is the clear compromise: 10 hours of call time, 16 hours of music playback, and a 10-minute charge for 2 hours of use. Weight is listed at 230g, the color is gray, and it carries a 1-year manufacturer warranty. No headphone jack — it's wireless only.
Buy it if your calls happen in noise you can't control, you move around a lot, or you want quick top-ups instead of overnight charging. Skip it if you need maximum runtime or prefer a boom mic you can physically reposition — the oleap relies on its voice pickup tech rather than a rotating arm.
Side-by-Side: Which Should You Choose?
• Best for battery life → Delton 50X. 35 hours talk / 40 hours playtime versus 10 hours talk / 16 hours playback.
• Best for wireless range and stability → oleap Noise Cancelling Headphones. Bluetooth 5.3 at up to 15 meters versus Bluetooth 5.0 at 10 meters.
• Best for a fixed desk setup → Delton 50X. The charging dock plus USB dongle is made for a permanent workstation.
• Best for fast top-ups → oleap Noise Cancelling Headphones. A 10-minute charge yields 2 hours of use; the Delton needs about 2 hours for a full charge.
• Best for blocking your own noise → oleap Noise Cancelling Headphones. Open-ear environmental noise cancellation versus the Delton's passive sound isolation.
• Best for repositionable microphone → Delton 50X. Its mic rotates 270 degrees; the oleap uses built-in voice pickup.
• Best for music listening → oleap Noise Cancelling Headphones. Stereo sound with BassLeap and up to 105dB output versus a monaural design.
If I had to pick one, I'd buy the oleap Noise Cancelling Headphones. In my opinion, the 50dB ENC call noise reduction, one-touch mute, and Bluetooth 5.3 range solve the problems that actually ruin work calls — being heard, and staying connected. The 10-hour battery is the real cost, but a 10-minute charge buying 2 hours makes it livable for most people.
That said, if you're a desk-bound professional who despises charging and wants a docked, always-ready headset, the Delton 50X's 35-hour talk time is hard to argue with. Check the current price on Amazon before deciding — the numbers above should make the call easy.
Yes, clearly. Delton rates the 50X at 35 hours of talk time and 40 hours of playtime, while oleap rates its headset at 10 hours of call time and 16 hours of music playback.
The oleap. Its VoiceOn tech is rated at 50dB of noise reduction and is aimed squarely at call centers, hotlines and busy co-working spaces. The Delton relies on DSP and ENC, which is a lighter approach.
Both are positioned for work platforms, and the Delton explicitly lists MS Teams, Zoom, Google Meet and Slack. The oleap is described for Teams, Zoom, PC, laptop and call center use.
The oleap, on paper. It uses Bluetooth 5.3 with a range up to 15 meters, while the Delton 50X uses Bluetooth 5.0 with a range up to 10 meters.
