Delinuo TWS-T9 do the minimum in design, the materials used and the care taken in the finishes do not inspire great confidence (note all the same the presence of an IPX6 waterproof certification), and this is all the more the case when we discover the transport case .
This one breaks records of size and weight: bring a very large pocket or a bag to take it with you. It only has the advantage of offering a large number of recharges and acting as a powerbank(external battery). The comfort provided by the intras is very average: the headphones are relatively large, the feeling of pressure at the entrance to the duct is relatively high and they are sensitive to vibrations caused by footsteps (solid-state transmissions).
The Delinuo TWS-T9 will still find their place in the big ears, but it will be difficult to keep them for long sessions. The maintenance is not incredible either: the fault in the slippery plastic coating used on the headphones.
The user experience is not very pleasant either. The usual commands are all available (even the volume), but it takes some time to tame them (a passage through the manual is very strongly recommended). In addition, the activation of controls lacks responsiveness and it happens regularly that we accidentally touch the panel while trying to reposition the intras. Many audio and voice indications are integrated, but their quality leaves something to be desired, which makes some particularly unpleasant. The wireless Delinuo connection via Bluetooth 5.0 did not show any big stability problems and it is possible to use the headphones in mono solo. Not surprisingly, the latency is nevertheless particularly high. Even when going through a mobile application natively compensating for a certain part of the latency, there is still a small difference between sound and image. The autonomy offered by this model is low: only about 3 h 30 min per charge.
If the experience of using the Delinuo TWS-T9 is just fair, it is a disaster in terms of sound performance. Very unbalanced frequency response, accuracy in picking up especially in the bass, absence of treble, distortion in the midrange / high midrange … this model combines the bad points. The sound reproduction is very muffled, the bass is omnipresent and overflows on the higher frequencies, the timbres are altered. It is very difficult to perceive the elements in the foreground correctly and the voices are struggling to be heard. In short, nothing is right.
True wireless intras Delinuo TWS-T9 sign a hell of a poor performance. More than ever, we advise you to go your way and look at other models that are really worth seeing, such as the JBL Tune 120TWS . They are certainly a little more expensive, but this is the minimum investment to acquire a good model of true wireless ultras .
