  • 3 pairs x Full foam Tips
  • 3 pairs x Donut foam Tips

Design, Fit and Build Quality:

The OURART ACG has a solid metal shell with a very different design language compared to all other erabuds (Yuin, MX500 etc.) on the market.

The shape of the front housing is inspired by the running wheel hub and is eye catching.

The titanium diaphragm in silver color is visible under the openings on the front side and has a nice appearance.

On the back of the erabud shell is the laser engraved OURAT branding.

They are a several numbers of vents around the monitor shell.

At the back of the earbud shell is the MMCX female connector that is allowing you to upgrade to the cable of your preference.

The OURART ACG is coming with a detachable cable that features MMCX connectors.

The MMCX connectors have a transparent plastic housing with Left (blue) & Red (right) indicators.

The cable is made of copper-silver hybrid wire and has a soft rubber coating. The cable features a metal chin slider in silver color.

The copper-silver hybrid wire cable of the OURART ACG features a microphone with remote control functions.

The cable of the ACG has a 45 degree profiled headphone jack with a 3.5mm TRS (unbalanced) connector.

The Sound:

The OURART ACG has an slightly warmer than neutral tonality, with a nice amount of bass for an earbud (especially compared to those of the OURART Ti7), a musical and transparent midrange and a treble range that is pretty crispy/lively.

 

Please note that the sound performance of earphones may vary from user to user as the fit and ear anatomy greatly affects the overall performance.

 

Bass:

The general bass character of the OURART ACG is on the linear side with a slightly coloration in the midbass area.

The subbass area of the ACG is fairly flat in response and shows an average depth and extension, while the overall intensity und rumble is enough for genres like jazz or acoustic music.

The OURART ACG shows some coloration in the midbass area that has more presence than the subbass region. This frequency area is adding the ACG earbud a nice amount of warmth and body and is very detailed for this price category. The intensity and speed of this frequency region is on a good level, especially for a sub 100 USD erabud, while the extension is on an moderate level.

They are no negative situations like a muddiness or a bass bleed that could affect the clarity and clarity and detail retrieval of the ACG.

A warmer and thicker than neutral source would be the ideal pairing for the OURART ACG.

 

 

Midrange:

The first noticeable character of OURART ACG’s midrange is the clarity that is presented while listening to my favorite tracks. The tonality is not analytical only a bit warmish but not very thick in its presentation.

When it comes to the vocal performance, I can say that both male and female vocals are represented in a quite clean, detailed and emotional way. Male vocals benefits from the lower midrange depth, while female vocals are vivid and crisp.

The OURART ACG performs pretty well and is showing a very nice timber with instruments such as guitars, violins or the pianos. The ACG is also quite good successful in terms of detail retrieval, clarity and for the separation of each note.

The nice out of the head presentation of the OURART ACG makes the listen to vocals and instruments very pleasant, especially for an earbud in this price region.

 

Upper Midrange and Treble:

The upper midrange of the OURART ACG is detailed and is showing good extension. The extension and emphasis shows a good performance from female vocals to the instruments. The 3 kHz range sounds pretty controlled without to show any unwanted sibilance and harshness.

When it comes to the treble range I can say that it performs pretty well for an earbud in this price range. It is detailed, is well presented and is adding a nice feeling of sparkle and air to the sound. Instruments such like cymbals, bells or flutes are well extended and don’t sounding metallic or unnatural, while the overall treble presentation stills quite controlled.

 

 

Soundstage:

The OURART ACG is one of the earbuds which has a quite suitable soundstage for a precise separation of instruments and vocals. The stage is spacious and airy and is showing a nice “out of the head” presentation. When it comes to the width and to the depth of the stage, the ACG is showing more wideness than its depth which is on an average level.

 

 

 

Some Short Comparisons:

 

OURART ACG versus TY Hi-Z 150S

The TY Hi-Z 150S is an earphone with good subbass amount and depth. The OURART ACG on the other hand shows less subbass quantity, but sounds more controlled in this area. The ACG’s midbass are superior to those of the 150S in terms of details and extension, which sounds somewhat veiled in this region.

The midrange of the OURART ACG shows slightly more clarity and detail than those of the TY Hi-Z 150S which sounds a bit warmer and fuller. The OURART ACG is superior in terms of female vocal performance, especially in areas like clarity and extension, while the TY Hi-Z 150S has the upper hand for male vocals due to its lower midrange depth.

The treble region of both the ACG and the 150S are detailed, while the OURART ACG has the slightly edge in terms of treble extension. It is showing a slightly more airy presentation has also a more natural sparkle in the upper treble region. The TY Hi-Z 150S is a bit sharp and prone to sibilance compared to the OURART ACG that shows better control in this region.

Both the TY Hi-Z 150S and OURART ACG are representing a “headphone like” experience when it comes to the soundstage. The main difference is that the soundstage of the OURART ACG has the upper hand in terms of depth, while the TY Hi-Z 150S has a slightly deeper stage.

 

OURART ACG versus TY Hi-Z F300M

The TY Hi-Z F300M has slightly more subbass quantity, depth and extension than those of the OURART ACG. The midbass area is showing similarities in terms of intensity and detail retrieval, while the ACG has the slightly edge for control.

The midrange of the TY Hi-Z F300M sounds a tad fuller compared to those of OURART ACG that shows otherwise slightly more clarity. Both earbuds are quite successful in terms of vocal and instrument presentation, while male vocals and instruments such like guitars or violas are more emotional with the F300M. The ACG on the other hand sounds more natural and emotional with female vocals and instruments like violins and pianos.

The upper midrange of the OURAT ACG shows a better and more natural extension compared to those of the TY Hi-Z F300M.

The treble range of both earbuds is well presented, while the ACG sounds more natural and controlled in this area. The OURART ACG has also the upper hand in terms of upper treble extension and detail retrieval. The TY Hi-Z F300M is somewhat sharp and a bit prone to sibilance.

The TY Hi-Z F300M and the OURART ACG are quite successful earbuds when it comes to the separation and accuracy of instruments and vocals. The soundstage of the ACG is wider, while the F300M has slightly better depth.

 

 

Conclusion:

The OURART ACG is a solid earbud that is made of metal, which has a very stylish and industrial look that separates it from other erabuds on the market. The amazing clarity and detail retrieval and the possibility of cable rolling making the ACG to a real bang for the buck.

 

Pros and Cons:

  • + Clarity and detail retrieval
  • + Treble and Midrange tonality
  • + Upper midrange control
  • + Build like a Tank
  • + Cable is Removable

 

  • – The quality of the stock cable is average (but quite acceptable for the price)

    Thanks for this great review 🙂

    I am interested in these. Have you heard the old rose Masya? Can you compare them?

    Also between these, rose Masya pro and smabat st-10, which one you prefer? Or other in the same price range.

    Best regards

      You are welcome Ricardo 🙂 I have had the old Masya few years ago, but have it no longer. But İ remember that it sounded fuller and more headphone like compared to the Ourart ACG, so it would not be an upgrade if you have already the Rose Masya. Sorry, but I didn’t have had the chance to listen and compare the ST10.

      • Ricardo Pinheiro says:

        Thank you 🙂 it helped me a lot! I want something good, not a downgrade.
        And of I have the rose Masya, but like to hear electronic, folk, punk rock, indie, would the EBX be better?

        • Gökhan AYDIN says:

          You are welcome 🙂 I would recommend the Astrotec Lyra Collection 32ohm instead of the EBX that shows less subbass depth compared to the Lyra.
