The Mpow EM12 Wireless Earphone is a mediocre mono Bluetooth headset for phone calls. Its in-ear design isn't the most comfortable during longer sessions, and it's 3.3-hour battery life is much less than the 6-hours advertised by Mpow. While the sound profile is very bass-heavy, it's decent for phone calls as most voices are detailed and clear, though some sibilants (S and T sounds) might be piercing and harsh. While its integrated microphone can't separate your voice from background noises nearly as well as a boom mic, its recording quality is surprisingly decent and your voice sounds natural and clear. Unfortunately, it uses a proprietary charging cable, which can be a pain if you lose or break it, though it comes with two included, which is nice.
The Mpow EM12 Wireless Earphone is mediocre for mixed usage. Since it only comes with a single earbud, it's a mono headset that's designed for phone calls rather than listening to music. That being said, the bass-heavy sound profile is well-suited to most popular genres and has a slightly excited sound that shouldn't be too muddy or cluttered. Unfortunately, the 3.3-hour battery life is disappointing and likely won't last through an entire work day if your job involves making a lot of calls. Due to not having a boom mic, your voice gets drowned out easily by background noise during phone calls, though on the bright side, your voice sounds quite clear and natural.
The Mpow EM12 Wireless Earphone is a mono Bluetooth headset and isn't recommended for neutral sound listening. Its sound profile is very bass-heavy and not very accurate, and its closed-back, in-ear design gives it a very closed soundstage. Overall, this headset is designed for phone calls and isn't the best choice for an accurate music-listening experience.See our Neutral Sound recommendations
The Mpow EM12 Wireless Earphone is only alright for commuting or travel. Its 3.3-hour battery life is quite short and likely won't last most flights or travel days. It may be okay for commuting, though its mono headset design makes it more designed for taking phone calls rather than listening to music.See our Commute/Travel recommendations
The Mpow EM12 Wireless Earphone can be a good choice for using while working out if you want to stay aware of your surroundings. Its bass-heavy sound profile helps to keep you pumped up at the gym, and it feels quite stable in the ear. The earbud blocks very little background noise while also leaving one ear fully open, so it's a good choice if you run outside where you need to be able to fully hear your surroundings.See our Sports/Fitness recommendations
The Mpow EM12 Wireless Earphone is only passable for listening to music at the office. Its in-ear fit may not be the most comfortable for everyone during long periods, and its 3.3-hour battery likely won't last an entire workday, even with breaks. Due to its mono, single-earbud design, it's meant for phone calls rather than music, unless you like listening to music with one ear to stay aware of your surroundings. On the bright side, it leaks very little audio, so your coworkers won't hear what you're listening to, even at higher volumes.See our Office recommendations
The Mpow EM12 Wireless Earphone isn't recommended for wireless gaming. This Bluetooth-only headset isn't compatible with Xbox One or PS4, though it should connect to any Bluetooth-enabled PC. While its recording quality is quite decent, its latency is likely too high for most gamers.See our Wireless Gaming recommendations
The Mpow EM12 Wireless Earphone is a Bluetooth-only headset that can't be used for wired gaming.
The Mpow EM12 Wireless Earphone is a mediocre mono Bluetooth headset for phone calls. The recording quality of the microphone is quite decent, and your voice sounds clear and natural, though it does a poor job of separating it from background noises. Its sound profile is well-balanced in the frequencies mainly responsible for most voices, so speech sounds very clear and detailed, though music sounds quite bass-heavy and muddy. Unfortunately, the 3.3-hour battery life is disappointing, and likely won't last a full work day if your job entails making a lot of phone calls.
The Mpow EM12 Wireless Earphone has a fairly straight-forward design that looks very similar to some truly wireless headphones, like the SoundPeats TrueFree/True Wireless. It's very small, covered in glossy black plastic, and has a much more casual look than most mono Bluetooth headsets with a boom mic.
The Mpow EM12 Wireless Earphone is decently comfortable. Some may find it causes fatigue during long sessions since its in-ear design enters the ear canal deeper than headsets with an earbud-style, like the Plantronics Voyager 5200 Bluetooth Headset. On the bright side, it doesn't put too much pressure on the inside of the ear, and it comes with three different tip sizes to help you find the most comfortable fit. Unlike the SoundPeats TrueFree/True Wireless, which is slightly curved, the EM12 is straight, so you can use it in either ear.
The touch-sensitive controls on the Mpow EM12 Wireless Earphone are easy to use and offer good, audio feedback. Unfortunately, it doesn't give you a lot of available commands and only allows you to play/pause music, answer/hang up a call, or reject a call.
The Mpow EM12 Wireless Earphone is extremely portable. Since it's essentially just a single truly wireless earbud, it's among the smallest headsets we've ever tested and can easily be tossed into any pocket or bag.
The Mpow EM12 Wireless Earphone comes with a good hard case. Unfortunately, unlike with truly wireless headphones, the case doesn't provide any additional charges. On the bright side, it feels like it should provide decent protection against drops or light rain exposure, and it can easily store the headset, both USB chargers, and the additional tips.
The build quality of the Mpow EM12 Wireless Earphone is good. Both the headset and the USB charging cradle are made from dense plastic and should be able to withstand most accidental drops or bumps without sustaining damage.
This headset feels fairly stable in the ear. While it lacks stability fins or an ear-hook, it's small enough that even with moderate head movements, it doesn't move around much.
The sound profile of the Mpow EM12 Wireless Earphone is very bass-heavy yet fairly sibilant. There's a lot of extra bass that brings thump and kick to music, though it causes some tracks to sound boomy and muddy. The well-balanced mids and low-treble make most voices sound detailed, present, and accurate, which is great for phone calls.
The frequency response consistency of this headset is outstanding. Provided you achieve a proper fit and seal with the included tips, you'll experience the same sound reproduction every time you use the headset.
The bass accuracy is poor. The entire range is very over-emphasized, resulting in a ton of extra thump, punch, and boominess in your music. However, this shouldn't affect voices too much on phone calls, as most voices don't reach these lower frequencies.
The mid accuracy is good. Low-mid is slightly over-emphasized, causing some voices to appear slightly cluttered and muddy, though the rest of the range is very accurate and natural. High-mid, the range responsible for most voices, is very well-balanced and even, so speech sounds present and clear.
The treble accuracy is okay. Luckily, low-treble, which is responsible for some higher-pitched voices, is very accurate and natural. Mid-treble is over-emphasized, causing some sibilants (S and T sounds) to be piercing and painful.
The peaks and dips performance of this headset is sub-par. There are some minor peaks and dips throughout the bass and mid-ranges, though they aren't too severe and noticeable. However, the large peak in mid-treble causes sibilants (S and T sounds) to sound sharp and piercing in comparison to the slightly recessed high-mid/low-treble ranges.
The Mpow EM12 Wireless Earphone is a mono headset and has no stereo imaging.
The soundstage performance of this headset is very bad. Since creating a large and speaker-like soundstage is partially dependent on having a speaker-like pinna activation, and in-ear headphones bypass the pinna (the outer ear) and don't interact with it, the soundstage is perceived to be small and located inside your head. Their in-ear design allows makes them much less open than headsets with an earbud design, like the Platronics Voyager 5200 Bluetooth Headset, or the Jabra Steel Bluetooth Headset.
This headset doesn't have any virtual soundstage features.
The weighted harmonic distortion of this headset is decent. There's some distortion at both high and moderate volumes, though it likely won't be noticeable to most people.
These are the settings used to test this headset. Our results are only valid when listening using these settings.
The isolation performance of this headset is poor. Despite its in-ear design, it doesn't block out much background noise at all. On top of this, since the headset only consists of a single earbud, the other ear will be completely open and not block any sound whatsoever.
The leakage performance of this headset is great. Even at higher volumes it barely leaks any sound, and people nearby shouldn't hear what you're listening to.
This headset has an integrated microphone in the earbud.
The recording quality of the microphone is decent. When on a call, your voice sounds clean, natural, and decently understandable, but fairly thin.
The noise handling of the microphone is sub-par. Because this headset doesn't have a boom microphone and the mic sits fairly far away from your mouth, your voice easily gets drowned out in even moderately noisy environments. If you want a Bluetooth headset with much better noise handling, check out the Plantronics Voyager 5200 Bluetooth Headset.
The overall battery performance is disappointing. Despite advertising a six-hour battery life, the battery only lasts around three hours off a single charge. While this may last an entire work day if you don't talk on the phone much, it likely won't be long enough if you're on the phone a lot during an average day. It also takes 1.7 hours to fully charge, so you can't just take a quick break to recharge it. Unfortunately, it uses a proprietary USB charging cradle, which can be a pain. On the bright side, two are included, so you can leave one in the office and one at home, which is convenient.
The Mpow EM12 Wireless Earphone doesn't have a dedicated companion app.
The Mpow EM12 Wireless Earphone has very good Bluetooth connectivity. It can connect to two devices at once, so you can easily listen to music off one device and answer a call from another, or switch between your PC and phone without having to disconnect. Unfortunately, latency is high on every device, though it's a bit lower on mobile devices while streaming YouTube videos. It's worth noting that some apps seem to compensate for this, so your real-world results may vary.

On the other hand, the Plantronics is more comfortable, has much better controls, a significantly longer battery, and a dedicated companion app with a ton of customization options.
The Mpow EM12 Wireless Earphone Bluetooth Headset is a better mono headset than the Jabra Steel Bluetooth Headset. The Mpow is more comfortable, has easier-to-use controls, looks and feels better-built, and has a better-balanced sound profile. On the other hand, the Steel's battery life is much longer, and the headset is rated IP54 for dust and water resistance, though this isn't something we test for. The boom mic on the Jabra Steel also does a better job of separating your voice from background noise, making it better-suited for noisy environments.
