Betron YSM1000 Headphones Review

The Betron YSM1000 have a premium look thanks to the silver buds and gold accents. They have a simple in-ear design that isn’t bulky and doesn’t stand out much; they look like bigger earplugs. They also have a transparent rubberized coating on the cables, which lets you see the wires inside and gives it a nice look. Unfortunately, they do not come in other color schemes to suit your preferred style.

They aren’t the most comfortable in-ears we’ve tested so far, and the fit will depend on if you can find the right tip size for you. In-ears enter the ear canal and might not be as comfortable for everyone. On the upside, they come with foam tips that some may find better to achieve a better air-tight and comfortable fit.

The control scheme of the YSM1000 is good and offers common functionalities like music/call control and volume control and track skipping (no rewind function on Android devices). The button layout is simple and easy to use, while buttons are very clicky and offer good feedback. However, the volume up button on our unit was a bit mushy, but we don’t know if this is common on these headphones or if our unit had a small defect. On the upside, you can trigger your device's voice assistant by a long press of the middle button.

Like most in-ears, the YSM1000 are very breathable headphones thanks to their design. They don’t trap heat under ear cups and won’t make you sweat more than usual if you use them during physical activity.

Like most in-ears, these headphones are very portable and fit in most pockets. It is very easy to keep them on you at all times. You can also store them in the included soft pouch that doesn’t add too much bulk and will still be easy to have on you.

The Betron YSM1000 come with a small squeeze-to-open soft pouch that will protect the headphones against light scratches and minor water exposure. It does not add too much bulk, which is easy to fit in most pockets.

For budget headphones, the Betron YSM1000 are surprisingly well-built headphones. The in-line remote is made out of metal, like the 1More Piston Classic, and the earbuds are fairly dense and shouldn’t suffer too much damage if dropped accidentally. The cables aren’t too thin and are also rubberized.

These in-ear headphones are fairly stable. They don’t easily pop out of your ears, like the 1More Piston Fit do. They should be suitable for running and light physical activity. However, since they are wired, be careful not to get the cable hooked or stuck on something as it will yank the headphones out of your ears. This shouldn’t be an issue for casual listening sessions.

The frequency response consistency is excellent. If the user can achieve a proper seal using the assortment of tips that come with the headphones, then they should be able to get the same bass and treble delivery each time they use the headphones.

The Betron YSM1000 have a decent bass performance. LFE (low-frequency extension) is at 10Hz, which is excellent. Low-bass, responsible for the thump and rumble common to bass-heavy music is over our neutral target by 2dB, which fans of bass may like. However, mid-bass, responsible for punch, and high-bass, responsible for warmth, are overemphasized by about 4dB and 7dB respectively. This makes the overall bass of these headphones deep and heavy, but also noticeably boomy and muddy.

Above-average mid-range performance. Low-mid is overemphasized by about 5dB, which will make vocals thick and cluttered. Mid-mid is within 1dB of our target curve, which is good. However, high-mid is under our target by 3dB which will have a small negative effect on the intensity and projection of instruments in the mix.

The YSM1000 treble range is sub-par. The response is rather uneven and mostly under our target curve. This will result in lack of detail and brightness on vocals and instruments, and could also negatively affect sibilances (S and T sounds) on cymbals.

The imaging performance is excellent. Their weighted group delay is 0.11, which is very low. The GD graph also shows that the entire group delay never crosses the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were exceptionally well-matched, which is important for the accurate placement and localization of objects (instruments, voice, footsteps), in the stereo image.

The soundstage is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods (1st generation) Truly Wireless or the Bose SoundSport Free Truly Wireless.

The Betron YSM1000 have good isolation performance. Despite lacking active noise cancelation, they isolate a good amount of ambient noise. They achieve more than 6dB of isolation in the bass range which is about average, and good for passive in-ears. In the mid and treble ranges, they reduce the outside noise by 15dB and 42dB respectively, both values being very good.

The leakage performance is excellent. These in-ears practically do not leak, so you don't need to worry about disturbing people around you unless you are blasting your music in a very quiet room. With the music at 100dB SPL, the leakage at 1 foot away averages 25dB SPL and peaks at 43dB SPL, which is quieter than the noise floor of an average office.

The in-line mic is decent. In quiet environments, speech recorded or transmitted with this microphone will sound relatively thin, but fairly easy to understand. It may lack a bit of detail and brightness though. In noisy environments, the mic will do a good job separating speech from ambient noise in moderately loud places, like a busy street, but it will struggle in much noisier conditions like a subway station.

The in-line mic has an decent recording quality. The LFE of 269Hz results in a recorded or transmitted speech that is relatively thin. The HFE of 2.7KHz suggests a speech that lacks detail and presence. This microphone could also be prone to lower frequencies noise and pops. However, the intelligibility of speech on this microphone will be decent in quiet environments.

The in-line microphone of the YSM100 is average at noise handling. In our SpNR test, they achieved a speech-to-noise ratio of about 18dB, indicating they are best suited for quiet and moderate environments. However, they will struggle to separate speech from ambient noise in loud situations.

These are passive headphones that do not require a battery.

There is no companion app to enhance your listening experience.

These headphones are not Bluetooth compatible.

These headphones have a wired connection so don’t have any latency issues, which is suitable for watching video content and gaming.

These headphones have a 1/8” TRRS connection that has mic support on consoles and PCs. Also, the box of our unit says they are iOS specific, but they still work with Android devices. They simply don't allow backwards track skipping, which they do on iOS. This is the only difference between the two operating system we've found.

The YSM1000 do not have a base/dock. If you want a versatile headset with a base that you can also use wired, check out the SteelSeries Arctis 7.
