How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the earbuds that cancel more noise and last longer between charges, choose CMF BY NOTHING Buds 2; if you need hi-res LDAC audio and the newest Bluetooth version, choose Baseus Bass BP1.
• CMF BY NOTHING Buds 2 — biggest strength: 48dB hybrid ANC with an adaptive mode that adjusts in real time, plus up to 13.5 hours per charge and a 10-minute top-up that returns 7.5 hours.
• CMF BY NOTHING Buds 2 — biggest trade-off: No LDAC or hi-res codec in the spec sheet, and Bluetooth 5.4 rather than the newer 6.0 standard.
• Baseus Bass BP1 — biggest strength: LDAC hi-res certification, volume-adaptive Active EQ, and Bluetooth 6.0 with multipoint connection.
• Baseus Bass BP1 — biggest trade-off: ANC-on battery drops to 7 hours per charge / 36 total, and its quick charge adds 2.5 hours rather than CMF's 7.5.
• Pick CMF BY NOTHING Buds 2 if noise cancellation depth and long, uninterrupted listening sessions matter most.
• Pick Baseus Bass BP1 if you want the best possible audio fidelity and the most modern wireless connectivity.
The Buds 2 leads with noise cancellation. CMF rates it at 48dB of hybrid ANC across a 5200Hz ultra-wide frequency range — that's the kind of spec aimed at low, rumbling noise like bus engines, train carriages and air conditioning hum. More interesting is the Environmental Adaptive mode, which re-tunes the reduction level as your surroundings change. That is genuinely useful if you move between a quiet office and a loud street in the same hour, because you aren't stuck manually cycling modes.
Sound comes from an 11mm PMI dynamic driver tuned with Dirac Opteo, and there's a 360° spatial audio effect built on an HRTF-based algorithm. Whether that spatial mode appeals to you is personal — I think of it as a film-and-gaming feature more than a music one. The Nothing X app lets you adjust EQ, Ultra Bass and ANC, switch on Low Lag Mode for gaming, and call up ChatGPT for voice interactions.
Battery is the other headline. Up to 13.5 hours per charge, 55 hours with the case, and a 10-minute top-up for 7.5 hours of playback. A full charge takes about 62 minutes. IP55 dust and water resistance covers workouts and rain. Call quality runs through six mics with AI Clear Voice Technology 3.0 and Wind Noise Reduction 3.0.
Baseus Bass BP1: Who It's For
The Bass BP1 Pro attacks the problem from the audio-quality side. It's certified Hi-Res and carries the LDAC codec, which Baseus says transmits roughly three times the audio detail of a standard Bluetooth stream. If you subscribe to a lossless streaming tier or keep a library of high-bitrate files, that's the spec that actually changes what you hear. Its Active EQ is volume-adaptive too, so bass and treble balance shifts as you turn the volume up or down instead of the sound collapsing into mush at high levels.
Noise cancellation is adaptive hybrid, using up to four real-time sensors tuned to 4kHz of wideband noise, with reduction rated up to -50dB. Five ANC modes live in the Baseus App, which is more granular control than most people will use but welcome if you like to dial things in. Six microphones with AI noise reduction handle calls.
Battery is where the trade-off shows. Baseus quotes up to 12 hours per charge and 55 hours total with ANC off — impressive — but with ANC on it drops to 7 hours per charge and 36 hours total. The 10-minute rapid charge returns 2.5 hours, and a full charge takes about 1.5 hours. The spec sheet also lists multipoint connection and DCLL low latency, plus five sizes of ear tips in the box, which matters if you've never found a stock tip that seals properly.
Buy it if: sound fidelity, LDAC and multipoint are your priorities, and you're fine charging more often with ANC running. Skip it if: you need maximum ANC-on runtime for long-haul travel.
Side-by-Side: Which Should You Choose?
• Best for ANC-on battery life → CMF BY NOTHING Buds 2, roughly 13.5 hours per charge versus about 7 on the Baseus with ANC running.
• Best for fast top-ups → CMF BY NOTHING Buds 2, since 10 minutes returns 7.5 hours against 2.5 hours on the Baseus.
• Best for audio fidelity → Baseus Bass BP1, thanks to LDAC and Hi-Res certification.
• Best for connectivity and multitasking → Baseus Bass BP1, with Bluetooth 6.0 and multipoint connection.
• Best for gaming and film → CMF BY NOTHING Buds 2 if spatial audio is your thing; Baseus if low latency plus multipoint matters more.
• Best for fit flexibility → Baseus Bass BP1, which ships with five sizes of ear tips.
• Best for call clarity → A near tie: both use six microphones with AI noise reduction. CMF leans on Wind Noise Reduction 3.0; Baseus leans on its sensor array.
In my opinion, the CMF BY NOTHING Buds 2 is the safer buy for most people. The 48dB ANC rating, the adaptive mode and the 13.5-hour single-charge figure cover the two things earbuds actually get judged on day to day: blocking noise and not dying on you. I'd only steer you to the Baseus Bass BP1 if you specifically want LDAC hi-res playback and Bluetooth 6.0 multipoint — and if you're willing to accept roughly half the ANC-on runtime to get them. Check the current price on Amazon before deciding, since that gap can shift which one looks like the better deal.
FAQ
CMF rates its hybrid ANC at 48dB across a 5200Hz range; Baseus rates up to -50dB with four real-time sensors. Both are adaptive. The bigger practical difference is battery: CMF holds up far longer with ANC on.
Only with ANC off. Both reach 55 hours total, but with ANC on CMF gives about 13.5 hours per charge versus roughly 7 for the Baseus. CMF's quick charge is also much stronger.
Both are IP55 rated against dust, water and sweat, so either works. I'd give the edge to CMF for its longer ANC-on runtime through a long session, and to Baseus if you want the extra ear tip sizes for a secure seal.
