So, I was asked for which BT headphones have the lesser background hiss.
I am talking in this case not of the hiss caused by the ANC, but of that caused by the internal Amp, and which is common to almost all BT headphones, some more (Beats Studio Wireless among the worse), some almost none.
Normally, apart for the serious cases like Beats, you do not notice this hiss while you are listening to audio.
You can generally only notice it during silence. For example, right after pausing music.
So if you pause the Music and you cannot notice any audible hiss, it is already good enough.
Now to check which headphones are even better than this, you wait a bit (a few seconds) till the headphone will turn its amp off, and if there was some hiss (which you did not notice because your ears were used to it) you can now notice that the hiss goes away and there is a cleaner silence.
If you do not notice any difference between pausing the music and, let's say, a time of 10 seconds, then your headphone produces no hiss.
I've never felt the hiss as a problem on any other headphone than the Beats, as far as I can remember.
But I have only tested headphones with music. While this guy who asked for help, is looking for something to use with TV, where the flow of sound contains much more silence.
So, further tests are needed.
I can only test for him the headphones I have now (or will receive in the future).
So, to everybody else here (and
@n00b2 you could ask the same in your Thread, maybe linking this post of mine), I would like to ask to make this hiss test on their BT headphones.
It could help other customers too and it is actually a cool idea.
About the ones I have here:
-Bang & Olufsen BeoPlay H8: almost no hiss. Pausing the music I have heard no hiss. When the Amp went off I could not notice any difference. So, at least in this the H8 are good, BUT, only if the ANC is off... Their ANC adds hiss. Anyway for TV use they are not good because they lack mids and low mids and the vocals sound distant and off, which in movies is very noticeable.
-Meelectronics Air-Fi Matrix2: same story here. Almost no hiss. These are nice headphones for the price. And they have more mids than the H8, vocals are more present. Only problem, the bass cannot be boosted much, only 3 to 6 db, or it distorts. And under 60hz it cannot be boosted at all. And out of the box, with no EQ, the bass is not boosted like in the H8, which many people would prefer for music, but for films a bit bass boost is good.
Now if you ask me, between H8 and Matrix2, for films and TV, absolutely the Matrix2. Clear present vocals, and louder than the H8, and MUCH cheaper.
-Audio Technica ATH-WS99BT: there is a little hiss which I could only hear when the Amp turns on (not when the Headphones turn on, but few seconds after they establish a connection) and which I could notice disappear when the Amp turns off. But during the music I could not notice it at all, and after pausing the music I also could not notice it till the Amp turned off. So, they are still very good, and apart being one of the best sounding BT Headphones imo, they are also very good for TV and movies because the bass is rendered very well (without being boosted. It is just, powerful and natural), the mids and low mids are excellent and vocals sound very clear and present, and the soundstage is very good, which not only for music but also for movies is cool.
-AKG Y45BT: these have a bit more hiss. Once again, for me not audible during music or during films, but compared to the ATH here I could hear it a bit more after pausing the music. They are anyway quite cheaper (less than the half) and even if not with the detail of the ATH they have also very present mids, and a bit boost in the bass, so that they work very good for movies.
-Bluedio R+ Legend: not at the level of the Beats, but the hiss here is clearly noticeable. With music I did not notice it so much and I got used quickly, but when pausing the music it was very clear. They sound more present than the H8 in the mids and have better soundstage.
Considering that I have just received and never before talked about them, I will say a bit more: they are not too bad. But absolutely not a GOOD pair of headphones. The sound signature is a bit dark in the bass and not very lively in the rest, and with EQ they improve a bit but not much. The bass is the opposite as it should be: boosted out of the box (= not good for lovers of balanced sound) but not well extended and it distorts easily if boosted with EQ (= no good for bassheads).
The overall sound is not very detailed, but also not bad. They do not have Aptx, anyway. And the soundstage, although quite good, is very far for being as impressive as Bluedio advertise it with all this of the 8 drivers.
The ATH have better soundstage with two drivers.
But, AT is AT
And the price is on another level.
I will be able to test the Pendulumic Stance S1+ in the next days, and also to re-test the Fidelio M2BT, so, stay tuned.
Now I am curious to hear the test of other people.
