I'm acoustic engineer in one of audio related company in Malaysia (not SONY
).
I have Sony 1ABT and just bought MDR-zx770bn at lazada Malaysia at RM402 two weeks ago. I tested MDR-1000x before go for MDR-zx770bn.
From my observation with SBC or Aptx,
1ABT
sounds wormer, more bass, less treble. Total package sounds more comfortable, good for long time period of listening. No ANC. It sounds great when listen at quiet environment, but the sound is totally different when u take bus or flight. The low frequency noise will mask over the bass and u will only hear mid and treble.
MDR-1000x
Good ANC, the ANC did not create uncomfortable sound. I notice a lot of ANC headphones created uncomfortable sound at mid range where the phase offset did not perform properly. The sound is quite balance, more treble and less bass compare to 1ABT. But it sounds a bit harder compare to 1ABT, this is the only reason stop me from moving to 1000x.
MDR-zx770bn
ANC not so great, I can hear a bit of uncomfortable sound at mid frequency. End up I use putty to block the ANC mic port to prevent mid and high frequency pass through the mic, so that only low frequency noise will be processed.
770bn is the worst compare to 1000x and 1ABT, too much of bass and high frequency (has the V shape kind of EQ). Need to manually tune the bass port to reduce the bass and high frequency.
The only item I like 770bn is the price, Audio technica ANC7B,ANC9, Bose QC15 all are above RM850! And without BT feature.
Now I'm using 1ABT at home (quiet environment), MDR-zx770bn for traveling (noisy environment).
Tested BOSE products, but I prefer SONY's sound character.
