need some clarification, please.
unsure if i need this item.
sensitivity ratings confuse me
(and i am googling this topic to better understand it...)
https://www.google.ca/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=understanding%20sensitivity%20on%20earphones%20and%20headphones
currently I'm using the FLC 8S
SPECIFICATIONS
- Driver unit: 8.6 mm dynamic drivers+ dual balanced armature
- Rated Impedance: 11 Ohm
- Sensitivity: 93 dB/mW
- Frequency response: 20Hz - 20KHz
attached to dragonfly red or chord mojo then to ipod touch 6
...but i don't hear any hiss ...so i presume I'm ok.
also the micro iDSD already has this iematch (for home usage)...so i presume I'm ok there, too.
(just saw an earlier posting about 5 or so pages ago when a poster shows the micro iDSD and the iematch
???
Because of very low impedance, FLC8S IEMs have very high sensitivity.
The 107dB/mW @ 11 ohms rating translates to 127dB/V. For reference, non-amped smartphones etc. usually produce between 0.5 to 1V output, with about < 100dB SNR.
According to Sony ZX1's measured performance (as stated here: http://reference-audio-analyzer.pro/en/report/amp/sony-zx-1-hp.php), this device has a maximum output level of 0.43V.
If iEMatch is used at the high sensitivity setting, its maximum SPL should still be > 105dB with a significant improvement in background hiss.
