The next found is a Sony model with the same price . I was however impressed with its time range at 35 hours with one charge! This is one of the reasons I bought it
So yet another
full plastic model so simple, a bit more than the JBL one Even a bit smaller one ! As it can be shown with the above picture the arm is nearly the 2/3s of the JBL
as with most headphones , the buds can be rotated. But also there is some tilt is not more than 15 degrees as it can be shown above
The next and final typical with them is the button arrangement. Volume or next /previous song plus the power on /off button And USB C for for charging!
They are very comfortable. They don;t irritate my head nor my mind.this is quite the second reason i bought them
As with remain models tested this also offers a nice female voice informing the status of the model. Messages as always use female voice In this model are noted after a short tone It also advises the status of the battery. I old prefer if hat could message as battery full only.
Reception by distance .
First test : distance with the Redmi 5a . good reception with minimal drops esp in the point with 2 walls in between . This is the only point that signal got some temporary drops. Outdoors there were also some point with twin walls killing the signal
Testing with laptop : reception was worse than with the Redmi with more drops on the same points I think that its wireless transmitter has lower power
I have used the same song when testing both as transmitters. same audio quality for both with good audio very close to JBL headphones.Second and more exhaustive check shown the Sony having a some increase on 500-1500 Hz range (middles and lower sharp tones and lack of the very deep bases ) as checked with the above and this song =with deep basses- from YouTube . Link to a friend singer.
Testing with with a TV and external transmitter : this mini gadget has been tested so far to have some trebly sound when receiving with the 81DJ headphone. at first check the transmitted didn't now couple with the headphones . I waited more than 90 seconds till the transmitter turned itself off . ON second try the transmitter still coupled slow but in shorter time! Sound quality between the wired headphones and this are nearly the same with nearly the same frequency response as tested with the first test.
Below is the tone test #1 as made with most earphones before using a lapel microphone by testing both JBL and Sony .
From what i understand from the screenshot this headphone has very deep basses even are not heard It was quite mysterious that all tones shown as lost in the local noise but only the near 1 Khz were audible. JBK shows a tune-in on 1 kHz while the Sony on 2kHz
As in result: 4/5 Sony headphones are quite good with a HIFi audio curve and very comfortable !
The headphone has been tested in another place in a irregular room with a fireplace in-between with 6x6 plus 6x3 [tilted] extension . The firs two tries were good but after them i seen again the problem happened with the two other BT headphones tested before: timeouts
Connection with the Hitachi android TV is rather quirk : every time i connect with the headphones I first must to do a new BT gear that means the bit code is possibly different
Another time the connection was reset in the middle of watching and i needed to restart 'pairing' as noted above! I cant understand what is the reason..
time testing between this and rthe inkax HP31
- Sony with smartphone 8 seconds
Inkax with smartphone <1 second
- Sony with TV >50seconds
Inkax with TV ard 5 sec
