I will be reviewing Kinera YH623 TWS IEM.Bought this YH623 TWS IEM from AK Audio Store( https://www.aliexpress.com/item/40004526909...MiWtNGuVH-jLaVA - Aliexpress store highly recommended because most of my bluetooth IEM have gone to audio heaven for reason such as dead battery and wiring problem !
What better way to head straight on to Bluetooth connectivity without the hassle of wiring restricting movement and the latest fad of TWS IEM . Also partly because of my new initiative to get fit again by getting KInera YH623 which I have tested while exercising and its such a boon to use it without the hassle of getting wire snag or adjusting the earpiece. Its amazing how technology has progressed from the first Walkman in 1979 to smartphone that does everything especially with the addition of TWS IEM.

So much for picture and let's move on with some aspect KINERA YH623 :-
BUILD & DESIGN
The packaging comes with hexagon box with all the specifications features listed on the front of the box.Accessories wise as listed above are standard fare as most TWS manufacturer will supplied - not much to complaint about.
The charging case is compact friendly and will easily fit into any pocket which has battery rating of 400mAh which will recharge the IEM for 3 cycle of roughly 5 hr of usage each cycle. Personally I'm very happy with the battery capacity and the ease of the automatic charging when the IEM is put back into the charging case every time. The only downside is there is no indicator as to the battery life on the charging case. Also the only way to ensure that the IEM is charging is to open the case to see the LED indicator on the outer face of YH623 is red while green means IEM fully charged. Its time to charge the charging box when the IEM is not charging - simple!
Design-wise tick my preference as it fits perfectly and also no adjustment needed once inserted . The metallic blue color or purplish is also very eye catching imo as compared to the pink option. Honestly I really like the finishing and shape of YH623. Its made of some sort plastic resin and there is a LED indicator on each side to show whether the earbuds pairing mode function is on.
The YH623 also has the ability to auto-pair with your phone as soon as they are taken out from the charging box. Touch control is located front face plate and need some getting used to its function as its touch sensitive which have led accidentally stop playback or activated Google VoiceAssistant on my Android phone. Bluetooth connectivity is also a breeze and will automatically connect once initial pairing done the first time.
Sound Signature
The sound design team of YH623 is clearly run by a BASSHEAD ! Quality audiophile aficionado need to look elsewhere for detailed sound or clarity. Its definitely throwback to my younger days affinity for exciting thumping music. Designed specifically for one who loves bass very much and those who can't take detailed high or those prefer warmish tone where the BASS is NUMERO UNO! In short bass is full of gusto and quite boomy for my taste.
Make no mistake this YH623 has power in term of energetic bass rumble and hit hards to the core of the soul where the vocal comes second in term of presentation. The soundstage is quite average where the positioning and placement of instrument is not precise.
The mid and vocal is recessive and personally I feel this IEM will cater specific music genre especially EDM or House music lovers. Treble detail and extension also play second fiddle to the overall musicality of the sound because the master of the house is Lord BASS .
Conclusion[I]
Bass centric TWS IEM and music genre specific! Though its not my prefer sound signature but I always say to myself - " just gotta find right hat for my head and not the other way around where the hat don't fit the head "
Therefore this Kinera YH623 will primarily used for exercise duty where the BASS is the star of the show and always ready to show its power every time it's ON ! Please read below with the BOLDED additional info!
After additional testing and running this YH623 further - my view of this Kinera YH623 went from good to great as before that was running through my Xioami Mi MIx 2 but all this CHANGE went I tested on my Cayin N3 and Shanling Mo DAP player - its no longer bass heavy and also the treble extension, soundstage and clarity are much much more better . Wow ..I'm impressed with it so much that my initial reaction was to work around it but now it can be a daily companion. The sound signature is totally different when tested with the phone but the jump of sound quality is so much better with dedicated DAP player! It went from mistress to wife material ! LOL
Currently AK AUDIO STORE is running promotion for this beauty for USD45 only for limited period https://www.aliexpress.com/item/40008022621...WnpfEFEeNPw3U7M which I personally think its a fantastic deal! What are you all waiting for especially this period where MUSIC is the best medicine for stay at home Covid period.
