Kinera Bd005 Pro Review – Do They Sound Like Beryllium?

Kinera has been a big game player in the chi-fi earphone market since 2011 and developed a variety of high end audiophile grade earphones. They have many patents for their custom tuned driver units in the earphone market. In the budget segment they have quite a few earphones like Seed, SIF, BD005, TYR and the latest BD005 Pro which is the successor to their BD005. Now the BD005 Pro is equipped with a hybrid driver system involving the 9.2mm beryllium dynamic driver and their custom tuned BA to deliver the sound. In this review let’s check out whether the BD005 Pro lives up to the name of Beryllium since they mostly sound nicer.

DISCLAIMER:

This unit is given to me as a part of a review tour conducted by the Hifigo Team. I have not been influenced by anyone to manipulate the review in any means and this review is fully based on my opinion and usage pattern. It may vary from person to person and depends upon the source you use.

SPECIFICATIONS:

Driver: 9.2mm Beryllium Diaphragm Dynamic Driver Unit and Custom Tuned 30095 series high frequency BA Driver.

2 pin 0.78mm connectors

Impedance: 26 ohms

Frequency Response: 20Hz – 20 KHz

3D Printed Earpieces

DESIGN AND FIT:

The earpieces are designed beautifully by providing them with 3D Printing. The faceplates are hand crafted and are meticulously designed. The faceplate has branding on it which is gold lettered and glitters of gold are spilled over the faceplate. The whole earphone is resin made and feels sturdy in the hand. The overall build quality is nice and the heft of the product gives nice premium feel in the hand. 

The 2 pin connector area is nicely flushed along with the body of the earpiece. There is a single pressure vent in the back side of the earpiece.. The nozzle is not very long but due to the custom shaped design the fit is really comfortable and exceptional. They isolate very well but here is the thing, including tips are really horrible. Nothing fits my ears and I just ended up using the third part ear tips. The included tips are barrel shaped and don’t fill the ear canal hence sound isolation is not good. The nozzle is covered by mesh and its silver plated. 

The included cable is a 4 core silver plated detachable cable which is average in feels. The cable is very sturdy of course but the premium feel is lacking. They are highly prone to tangling and have a sticky texture to the cable. The ear guides are nice and feel comfortable. The surprising thing is they have included a mic in the cable which most of the chi-fi earphones don’t have. The mic quality is average but hey something is better than nothing. The 3.5mm is gold plated and it’s a L shaped jack.

SOUND:

Source: iPhone + FiiO Q3, Apple Lightning 3.5MM Dongle.

The overall sound signature leaned towards bass and it felt like a W shaped sound signature. The bass is plentiful and the custom tuned BA is very good in retrieving the detail well enough. The timbre is not good and the tonality is way out of the park. The tonality is very metallic and not natural. For me if an earphone falls out in the tonality then it’s definitely a no go from my side. Let’s talk about the sound in detail.

BASS:

The bass quantity is very nice, has nice extension in the low end and digs deeper when the sub bass hits. The problem is they are very less resolving and feel congested in the bass region. As these possess beryllium drivers I thought this is going to have some nice bass but it disappointed me. Surprisingly they have a nice texture to the bass

In the bass, apart from the congestion and the lack of resolving tendency it also lacks slam. The mid bass hump made the bass weaker in slam hence the sub bass feels weaker even though they have nice extension and rumble. When playing bass heavy tracks they struggle in the bass region and to mask that lack of resolution they pump up the quantity over the quality.

The beryllium always possesses a faster decay and attack as per my testing but BD005 pro’s attack is slower and the decay is pretty slow. There is no sense of feel when the sub bass notes ends. Overall for casual fun listening these beryllium will satisfy you.

Tracks Used:

  1. Bigfoot – MALFNCTION
  2. Bad Guy – Billie Eilish
  3. Why so Serious – Hans Zimmer

MIDS:

The mids are fine and good but not great. They sound very thin in the mid range; they lack body due to the recessed lower mid. The upper mid are elevated more than the lower mid. The upper mid are uneven in nature and hence there is a hint of graininess.

The guitar strings strike nicer and the drums have nice attack too but they don’t sound natural. They sound slightly plastic. The tonality is way off and has timbre issues. The vocals sound slightly recessed where the female vocals sound more forward than the males. The vocals get very shrill when the volume is increased and gets slightly sibilant especially when the female vocals appear.

I would have preferred a slight boost in the lower mid than the upper mid thus reducing the shrillness and thinness in the mid section.

Tracks used:

  1. Cardigan – Taylor Swift
  2. For The Good Times – Perry Como
  3. Something Happened On The Way To Heaven – Phil Collins

TREBLE:

The treble extension is not great because it was taken care of by the custom tuned BA by Kinera. There is a good amount of air in the high notes and nice separation too. Everything felt fine for the price and suddenly observed the Sibilance which totally destroyed those good impressions over it. The tracks like MOVE YOUR BODY –SIA just makes you scream in sibilance. The BA does a good job in retrieving the detail in the treble region but fails to control the sibilance. 

There is also a hint of graininess. They definitely don’t appear smooth and have some treble peaks. The lack of treble extension makes it less enjoyable and rolls off in the upper end earlier.

Tracks Used:

  1. Move Your Body – Sia
  2. Graffiti – CHVRCHES

TECHNICALITIES:

SOUNDSTAGE: The soundstage is not wide or deep but average. Since the bass feels very congested they don’t give a sense of a big soundstage. They have a good amount of space between the instruments but it’s not the widest I have seen. 

IMAGING: They are average too. The instruments move nicely from the left to right and have smooth transitions between the channels. 

The layering is not good at all. They fall off very badly and due to the lack of resolving and congested nature the layering feels weird and not good overall.

VERDICT:

BD005 Pro, the budget offering from the team Kinera excels in some aspects like the quantity of bass, both bass & treble extension and detail retrieval in the high end but falls off in other aspects like the technicalities, resolution etc. Of course at this price point nothing can be expected to be extraordinary but at least should be able to compete with the other competitors in this price point, but during my testing the BD005 Pro fails. This a strong competitive segment where some great earphones like Tin T2 Plus, HM Heart Mirror etc are available for covering technicalities and if you want that good resolving bass the Pai Audio DR2 is available. 

So for 50USD this doesn’t satisfy me but your mileage may vary. You may like it so it’s better to give this a try before concluding the remarks. For now the Tin T2 Plus and HM Heart mirror are still the contenders to beat in this price point.

PROS AND CONS:

PROS:

  1. Well extended W shaped sound signature
  2. Excellent Fit and Build
  3. Bass Quantity

CONS:

  1. Lean lower mid section
  2. Sibilance
  3. Average technicalities
  4. Average Resolution
