Small charts, or large: D (Strictly not judge first review in principle)
Case
1) Soft-touch plastic very pleasant to the touch;
2) It is not a compact, compact, could not even see the photo!
3) It is convenient to recharge the phone from the case study, the minus is that you need to carry postings, but when there is no power outlet is a very good option, for example if you do not pay attention to charge your phone in the morning and went somewhere else (yes, the charge is not a lot, but a few important calls will be enough, maybe for more).
Headphones
1) conveniently enough, but there
but it is very important choose the right ear pads and better not from complete, as they are shorter than standard ear cushions, the parties will act on the headset on and thus be better to keep the ear such as large ears, and vice versa, the standard would be better to sit in the small ears. Just depends on the sound quality, the headphones can be kept in the ear but do not fit the ear canal and basso example will be gone.
2) The sound quality is very good, both for the bluetooth headset. Have something to compare, I used headphones (sennheiser cx 300-II; sennheiser cx 3.00; sennheiser cx 5.00; Panasonic RP-HJE125; meizu POP; sennheiser HD 201; JBL T110; SONY mdr-400). Compared with Meizu POP sound better, more bass and the bass is played purely something there, (it is difficult to convey the sound quality because it is subjective for everyone), not as a bassist as Panasonic 125, but approximately to them, it is best compared to the bass like them JBL T110. On the upper and middle frequencies are not all bad, quite clean (again, as for the price, is not even bad).
3) The volume, noticed that the phone is much louder than playing on a computer or laptop, put on the fact that the phone is a newer version of bluetooth, but it's not exactly: D
4) Now, about the delay in the YouTobe it is almost there, not at all noticeable. In games it (the delay) and have felt (tested on geometry dash game).
5) Operating time was not able to verify and to be honest there is no desire, just as many do not listen to music, but I can say that 3-3.5 hours they played at maximum volume exactly 100%. Plant complex, at least to me.
how to connect . Little instruction, if you listen to headphones individually the right earpiece will appear in bluetooth settings like HAVIT I93, and the left as the Mono I93. But if you listen to them together, it turns out that the left is connected to the right and the right in turn connects as HAVIT I93 (to prove I can say that while listening you put the left earpiece in the case, the right to play no longer, and if put right music stops and starts to search for the left device and connect automatically as the Mono i93). Which would connect both of them, it is necessary, not including bluetooth on the phone to remove both earbuds out of the case and hold it in her arms for a few seconds (or inserted into the ears) as long as they connect from one another, then the right earpiece go into bluetooth pairing mode about what will indicate blinking red and white indicator just below the mechanical button. Only then can include bluetooth in the phone. Just been cases that people take out one earphone or faster than the second one and it connects, or take out one inserted into the ear and not senhronizirovavshis second during this time, the first earphone again connects one
