      TWS21 SongBirds Airbuds

      Great BUDS for mini $

      I bought this mainly for phone calls and listening to u toob and watsap media while out and about. Also I prefer this model because I do not like buds sticking into my ear canal while working.
      For the mini$, and to compare apple with apple it surpasses apple's sound quality. Of course there are pears and oranges out there but this TWS21 knocks them out of two football fields into the jungle. The model should be TWS21-L(eg to kick).
      Soundstage is large complementing its size and price. Sound timbre is great. Piano, the most difficult to reproduce, sounds like a piano. Does not sound tinee like the price. EQ could do will a little reduction in mid, increase both in low (for kick and bass presence) and highs for cymbal clearness and clarity.
      Just to proof a point, I downloaded an EQ app for some fine adjustment. I do not like EQ apps because it reduces the dynamics of the original signal. With EQ, this little TWS21 ZOUNDS Great. Just for a test, 60hz was up +3db and the kick came alive. 250@+2db, Bass guitar was present. 10k@+2db cymbals were shiny and crystal shimmering. This is just to proof that this buds could be EQ'ed. However I do not intend to use the EQ app due to it reducing the source dynamics. I can live with the factory eq for now.
      I reckon Uiisii could develop a flat sound with a user adjustable EQ model.
      Due to small size, operating as Stereo, only way to listen to music, will run it down very quickly. Looking at the battery indicator on the phone, seems like slightly less than 1% / min consumption.
      I don't use this for exercise, so cannot comment on it but normal walking, socialising head movement and eating would not dislodge the buds.
      The case is super smooth. I have drop it a few time while picking it up. Trying one-handed opening without paying attention while shoot the case into the air. Could do with rubber grip.
      The negatives outgun the positives for TWS21 for its price.

      Fit well

      These are amazing!
      I have not had one problem with them. they aren't loose fitting in your ear and fall out like other ones I have had. The price is far less than its value.
