KBEar, the brand based out of China is a well established brand in the market. Their previous releases did make a presence in the market and the Believe was the favourite product of mine from the house of KBEar. They do have a variety of in-ear monitors ranging in budget to mid range segments and in this review the IEM that we are going to see comes under the ultra budget category and does deliver some impressive sound named ROSEFINCH and let’s dive into it!

The sound profile of the Rosefinch follows a nicely tuned L shaped curve. The tone is pretty natural with warmth added to it. The technical aspects are pretty decent for the price and do deliver some nice resolution. The Bass being the star show here delivers one of the best sub and mid bass in this price range. The other frequencies are taken care of too and in the following section will discuss them in detail.

The single DD with Silicon composite biological diaphragm indeed delivered some nice tighter and fun sound overall ♥️


The bass in the Rosefinch is one of the best aspects and the star show. Both the sub and the mid bass section have enough presence. The sub bass digs deeper with great reach thus providing those nice rumbles when the bass drops.

The mid bass is plenty in quantity and makes the whole presentation fuller and warm enough. Even with higher quantities the quality hasn’t been compromised. The bass does have control and adequate separation thus making them clean. The kick drums and the bass guitars have a nice natural tone to it with added warmth for the pleasing appeal.

Overall the bass here is rich in quantity and yet has mastered the quality too with nice control and separation. 


The sound signature being a L shaped curve the mid section is pretty neutral. There is no noticeable recession thus making the vocals and the instruments shine.

The presentation is pretty forward and sits in a comfortable position. The vocals get the adequate fullness and warmth from the mid bass presence. The fuller presentation never interrupted the clean sounding aspect of the Rosefinch. The piano notes and the snare drums do sound pretty clean with a natural and warm timbre.

Both the male and the female vocals get adequate presence with enough upper mid emphasis. There are no upper mid spikes seen thus making the listening experience very pleasing in the longer run.


The treble section when seen in the graph shows the evident roll off and the same applies in reality. Even though the treble has an early roll off they are definitely not that bad in terms of delivering some essential details out of the track. The shimmer however cant be expected because of the roll off but the needed instrumental presence can be observed. The electric guitar strings, cymbal crashes and the trumpets do sound and have good presence but the lack of added brightness led to a relaxed treble.

Since the brilliance is lacking in this set the percussion instruments do struggle to shine but the presence can be felt in a smoother and a calmer way. The notes are made calmer and soothing rather than attacking and vivid. This tuning can never be considered as a mistake since it does please those who love the relaxed treble section.


STAGING: The staging has enough width and height to represent a grand presentation. The width is slightly more than the height making the imaging an easier thing while the bigger bass also helps in providing a nice deeper sensation in the staging.

IMAGING AND LAYERING: The imaging and layering is pretty neat where the channel sweep and the transient response felt smoother and no stutters were observed. Even in the busier tracks the placement of the instruments can be pointed out precisely enough.

The detail retrieval is good for the price where it does deliver some essentials out of the track. The ultra high resolution can’t be expected at this price point and especially in this kind of tuning the details it delivers is something that needs to be praised.


The Rosefinch, the latest offering from the house of KBEAR is a well furnished and neatly tuned package. The L shaped curve fits well for this IEM giving enough bass pleasure to the consumers and at the same time enough details are delivered. Pricing is made great thus this package is definitely the star show in the year 2023 under 20 usd.

The build is pretty usual with resin mould and a Zinc alloy faceplate giving a touch of premium feel. The fit is excellent, providing a neat isolation. The cable is a TFZ 2 pin type and the quality seems to be average and for the price it can’t be complained about.

The sound is just sublime for this price and targeted audience. As a general consumer and as a bass lover would find this Rosefinch a great BOON! while the audience with more treble needs will get slight disappointment. The bass is elevated a lot making the sub bass shine a lot and extracts those subtle rumbles from the track. The mid bass warmth makes the whole presentation fuller and deeper with great control. The mid section feels neutral with a warmer tone and no noticeable recession making the vocals and instruments take a front seat giving an engaging experience. The treble takes the early roll off hence the shimmer and brilliance gets lacking but yet never compromised on delivering some essentials out of the track.

The technical aspects are pretty good since it has good enough staging making the imaging and layering to be on point. Since the bass is bigger, it does even give a nice deeper stage sensation throughout the presentation.

Overall, the Rosefinch is a well tuned package with a thick and juicy sound  and is definitely my pick under 20usd in the year 2023 since its “FUN”TASTIC!
