CMF Buds Pro 2 or Soundcore P40i for Android phones?
If you use an Android phone, both the CMF Buds Pro 2 and Soundcore P40i are strong budget wireless earbuds, but they focus on different strengths. The CMF Buds Pro 2 is the better pick for sound quality, LDAC, dual-driver design, and detailed controls. The Soundcore P40i is better if you want longer battery life, multipoint connectivity, wireless charging, and a bass-heavy sound.
For most Android users who care most about music quality and advanced audio features, CMF Buds Pro 2 is the better overall choice. If convenience and battery life matter more, the Soundcore P40i makes more sense.
CMF Buds Pro 2 vs Soundcore P40i at a glance
Both earbuds work with Android phones through Bluetooth, so basic compatibility is not a problem. CMF lists Android compatibility starting at Android 6.0, while the P40i can also be used with Android and has a dedicated soundcore app for settings and customization.
| Feature | CMF Buds Pro 2 | Soundcore P40i |
|---|---|---|
| Best for | Sound quality and Android audio features | Battery and everyday convenience |
| Drivers | 11mm + 6mm micro-planar tweeter | 11mm composite |
| ANC | Hybrid ANC, up to 50 dB | Adaptive ANC |
| Codec | AAC, SBC, LDAC | SBC, AAC |
| Battery with case | Up to 43 hours | Up to 60 hours |
| Earbud battery | Up to 11 hours with ANC off | Up to 12 hours in normal mode |
| Multipoint | No major advantage here | Yes, Dual Connections |
| Wireless charging | No | Yes |
| Water resistance | IP55 | IPX5 |
| App | Nothing X | soundcore |
| Special feature | Smart Dial case | Case works as a phone stand |
| Low-latency mode | Yes | Yes |
Specifications can vary with codec, volume, ANC, and other settings, so advertised battery figures should be treated as maximum test results rather than guaranteed everyday use.
Which is better for Android sound quality?
The CMF Buds Pro 2 has the stronger hardware setup for listeners who care about detail. It uses an 11mm bass driver plus a 6mm micro-planar tweeter, while the P40i uses an 11mm composite driver. CMF also supports LDAC, which can provide higher-quality Bluetooth audio when the Android phone and listening app support it.
The P40i takes a different approach. It is designed around a strong bass presentation and includes BassUp processing. Independent testing also found both earbuds bass-heavy, with the CMF having a somewhat more balanced sound and the P40i producing a more excited sound profile.
That makes the choice fairly simple:
- Choose CMF Buds Pro 2 for more detailed and flexible listening.
- Choose P40i if you mainly want powerful bass.
- Choose CMF if your Android phone supports LDAC and you want to take advantage of it.
- Choose P40i if you prefer to adjust your sound through Soundcore’s HearID and EQ features.
Why LDAC matters on Android
LDAC is one of the biggest reasons to consider the CMF Buds Pro 2. It is a Bluetooth audio codec designed to transmit more audio data than basic codecs such as SBC.
However, having LDAC does not automatically make every song sound better. Your phone, earbuds, Bluetooth settings, and source material all matter. If you mostly stream standard-quality audio, the difference may not be important enough to choose the CMF on this feature alone.
Which has better noise cancellation?
Both models have active noise cancellation, but their approach is different.
The CMF Buds Pro 2 uses hybrid ANC rated by CMF at up to 50 dB and includes a transparency mode. It also has three microphones in each earbud and Nothing’s Clear Voice Technology 2.0 for calls.
The P40i uses adaptive ANC that adjusts to surrounding noise. Soundcore also includes a fit test through its app, which can help users choose ear tips and improve the seal needed for effective noise reduction.
For everyday use, fit matters almost as much as the advertised ANC number. An earbud that does not seal well can let outside noise through even if its specifications look impressive.
Winner for Android users: slight edge to CMF Buds Pro 2, especially if you also value call quality and sound detail.
Which has better battery life?
This is where the Soundcore P40i clearly wins.
Soundcore rates the P40i for up to 12 hours on a single charge and up to 60 hours with the charging case under its stated test conditions.
The CMF Buds Pro 2 is rated for up to 11 hours with ANC off and up to 43 hours with the case. With ANC on or transparency mode active, CMF lists up to 6.5 hours from the earbuds and 26 hours with the case when using AAC.
| Battery use | CMF Buds Pro 2 | Soundcore P40i |
|---|---|---|
| Earbuds, ANC off | Up to 11 hours | Up to 12 hours |
| Total with case | Up to 43 hours | Up to 60 hours |
| ANC use | Up to 6.5 hours per charge | Up to 10 hours in Soundcore’s stated normal test conditions |
Actual battery life will be lower or higher depending on volume, codec, calls, ANC, and other features.
If you regularly forget to charge your earbuds, the P40i’s larger total battery capacity is a real advantage.
Which is more convenient for Android users?
The P40i has one of the more practical feature sets for everyday phone use.
It supports Dual Connections, allowing it to connect to two Bluetooth devices. This is useful if, for example, you use the same earbuds with an Android phone and a laptop. Soundcore provides the feature through its app.
The P40i also supports wireless charging, which can be useful if you already have a Qi charging pad. Its case doubles as a small phone stand.
The CMF Buds Pro 2 has a more unusual control system. Its charging case includes a customizable Smart Dial. You can use it for functions such as volume control, playback, noise-control modes, voice assistant access, and other commands through the Nothing X app.
So the convenience winner depends on what you value:
- P40i: better for multipoint, wireless charging, and long battery life.
- CMF: better for unique physical controls and customizable functions.
Which has the better Android app experience?
The two brands take different approaches.
The Nothing X app gives CMF Buds Pro 2 owners access to sound presets, custom EQ, ANC controls, low-latency mode, Smart Dial settings, and other earbud controls. CMF also supports Google Fast Pair on compatible Android devices.
The soundcore app gives P40i users access to adaptive noise cancellation, HearID sound customization, gaming mode, firmware updates, and other settings.
Neither app is a reason to avoid the earbuds. The better choice depends on whether you prefer Nothing’s audio controls or Soundcore’s customization tools.
What about phone calls?
The CMF Buds Pro 2 has six microphones in total, with three in each earbud, and Nothing uses Clear Voice Technology 2.0 for call noise handling.
The P40i also has six microphones with AI-based call processing according to Soundcore’s product information.
Independent testing gives the CMF Buds Pro 2 an advantage in microphone performance, with RTINGS finding its microphone system more accurate and better at filtering background noise than the P40i.
If you often take calls outdoors, in a busy office, or around other people, CMF Buds Pro 2 is the safer pick.
Which is better for gaming on Android?
Both earbuds have low-latency or gaming modes, so either can work for casual mobile gaming.
The CMF Buds Pro 2 includes Low Lag Mode through the Nothing X app. CMF also gives a specific low-latency figure for Nothing Phone devices when Game Mode is enabled.
The P40i includes Game Mode through the soundcore app. Soundcore notes that using Game Mode can reduce latency but may affect audio quality and some other features.
For serious competitive gaming, neither should be treated like a wired gaming headset. Bluetooth latency can still vary by phone, game, and connection conditions.
For normal Android gaming, both are good enough, with the P40i having an advantage if low latency and long battery life are your main priorities.
Which is more comfortable?
Comfort is highly personal because ear shape and ear-tip size vary.
The P40i includes multiple ear-tip options and has been found in independent testing to have a slightly more comfortable fit than the CMF Buds Pro 2.
The CMF Buds Pro 2 weighs about 4.9 grams per earbud, and its case and earbuds together weigh about 55.8 grams.
If you plan to wear your earbuds for several hours, focus less on the published weight and more on how well the ear tips seal without creating pressure. A good seal also helps ANC and bass performance.
Which is better for workouts and outdoor use?
Both have some water and dust resistance, but neither should be treated as a swimming earbud.
The CMF Buds Pro 2 has an IP55 rating for the earbuds.
The P40i is rated IPX5, which is designed to handle water jets but does not make the earbuds waterproof for submersion.
For normal walking, commuting, and light workouts, either can work. If you sweat heavily, wipe the earbuds down and keep the charging contacts dry before putting them back in the case.
Two Android user scenarios
Scenario 1: You use a Samsung Galaxy phone for music
Suppose you mainly listen to Spotify, YouTube Music, podcasts, and downloaded music.
In this situation, the CMF Buds Pro 2 is the more appealing choice if you want better audio flexibility, LDAC support, dual drivers, and customizable sound. Its shorter total battery life is unlikely to matter if you charge the case regularly.
Scenario 2: You use an Android phone and a Windows laptop
Suppose you listen to music from your phone during the day but also use the same earbuds for your laptop.
The P40i becomes more attractive because its Dual Connections feature can keep two Bluetooth devices connected. Its 60-hour case-rated battery and wireless charging also make it convenient for frequent everyday use.
