Sivga M300's Review - Close to an Open Backed Headphone
General/Packaging/Comfort/Build
Sivga has been aggressive in the year 2025, churning out one after another IEMs/Headphones. Of course there are some hits and misses, but we’re not here to discuss this today. I have the Sivga M300 with me today, which is their latest flathead/earbuds, mind you, despite the pricing, the sonic performance of it is generally very good. With a wooden housing that is pleasant to look at, as well as affecting the sonic performance, but we will go into that in the later part.
For the packaging, it is very straightforward and standard, nothing to fault.
Build quality and finishing is good and there is nothing to fault given the asking price, comfort wise, there are no sharp edges as well as any protruding design that causes discomfort throughout the listening session, but for earbuds, it is always tricky to get a good fit compared to IEMs, so do take into consideration that if it fits my ear well, it might not be for you.

Foreword
My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far
Sound Impression (M300 with foam)
Right out of the box, the M300 delivers a balanced and tonally pleasing sound. Timbre feels natural, and note weight strikes a good middle ground—not too thin, not overly thick. To my ears, the mid bass is slightly emphasised, but vocals remain present and never feel buried. Overall, it’s a nice blend of fun and technicality. I am using the M300 with a foam cover as it doesn’t fit well without foam for me, so indirectly it affects the noteweight and mid bass by boosting it a little
The unit was run in for approximately 30+ hours before writing this review
Bass
Bass has good texture and it is not thin sounding, the sub bass however is rather linear which is to be expected from an earbud, it is not to say that sub bass is non existent, but rather it rolls off slightly earlier
Overall extension in this frequency range is okay given the price
Sub bass rumble is there but as mentioned previously, it rolls off quite early
Mid bass however is punchy and has good texture, speed is average, not too slow nor too fast
Bass also doesn’t bleed into the mids nor muddy sounding
Mids
The mids are not recessed nor too forward but still lush sounding to my ears
Vocals sit comfortably, it is not overly forward, not lost in the mix and it avoid any shoutiness
Male and female vocal has good texture to it and doesn’t sound thin
The bass doesn’t bleed into this range which is good
Pinna gain is rather safe and never shouty even when the volume is being cranked up
Treble
The treble has enough energy to offer some sparkles and air, yet it is not overly done to the point where it is harsh (this is my impression with the foam cover on, the treble does get slightly boosted without the foam cover, hence giving it better resolution and detail retrieval capability, but sadly M300 without foam cover doesn’t sit on my ears well)
The treble does have some air to it to not make the track sound congested
The con is that the resolution is just average the same goes to detail retrieval as well, but given the asking price of M300, i would say it can actually trade blow with some IEMs that are slightly expensive
Soundstage/Imaging
Soundstage is slightly out of your head with good width, depth, height perception is also good
Imaging is good as the instruments can be pinpointed easily even during busy track, but of course if i were to nitpick, there are also certain complex orchestral tracks that might not perform that well
In terms of technicalities, M300 has good enough technicalities but if you are expecting M300 to be highly technical, then M300 is not it
Driveability
M300 is not hard to drive, based on my observation with amplification, M300 doesn’t seem to benefit much of it, so any entry level or mid range dongle will work just fine
Using it with my xDuoo XD05T, M300 seems to be sounding a little thicker with more body
Comparison (Moondrop U2 Flat Head)
Moondrop U2 to my ears is warm neutral that is easy to like but the bass in terms of quantity is lesser compared to M300, also it is thinner sounding
Slightly energetic treble compared to M300
In terms of ergonomics, it’s safe to say, M300 has way better ergonomics and comfort compared to U2, the cable gets tangled very easily and it takes a lot of time to untangle compared to M300 which is not that prone to the issue
Soundstage is rather average in terms of height and width perception
Note weight is on the slightly thinner side compared to M300
Overall, i would consider the M300 to be a better performer and offers a better listening experience compared to U2
Final Thoughts
All in all, the M300 is good as it is and it does everything alright and for the asking price, there really isn’t anything much to fault to be honest. Relaxing listening experience with good enough technicalities and wide soundstage that is on par with some entry level open backed headphones minus the size of the headphone. Recommended!
