TECHNICAL SPECS: The Westone W40 features four balanced-armature drivers with 118 dB @ 1mW sensitivity, 10Hz - 18kHz frequency response, and an impedance of 30 ohms @ 1kHz 解这个一元一次方程, 求出 80 dB 对应的电压是多少。 V = SQRT ( 0.001*30 ) / 10^ ( (118 - 80) /20 ) V =...
The HD 650 have far more detail and are still very smooth.They have about the same deep bass. There is maybe more bass detail in the HD 650 but more thud in the EL-8.The EL-8 have more sensitivity when driven by the same voltage....
This is complemented with the 105 dB/Vrms sensitivity, which translates to ~96 dB/mW. Noting these values are at 1 kHz and dynamic drivers can have an uneven impedance curve, I will say the HD 490 PRO is still among the easier headphones to power. You can get it plenty loud off even...
I am not sure of the reviewers aim, 105ohm and Sensitivity at 110db headphones within a mobile phone site, kinda pointless as no phone with 3.5mm unbalanced (except old onkyo dp-cmx1 using balanced output) can drive it to full potential. However, it's possible with a DAC with balanced...
hd 660s2 has also been revised to match the legendary hd 600 & 650, resulting in an impedance of 300 ohms. the coil offers a high magnetic force and electrical damping for a clean impulse response. it also increases sensitivity over the entire frequency spectrum by using th...
If you got satisfied volume with 58x, you'll be likely to get similar volume with 6xx due to sensitivity is pretty close. Impedance is not really relevant with smartphone due to OTL/OCL circuitry Device tested Motorola G Power 2023 (headphones jack only) Motorola G Stylus 5G 2023 (...
Sensitivity 96 dB SPL/mW Impendance 65 Ohm A alexmshore macrumors member Nov 3, 2011 32 35 UK Sep 9, 2013 #17 The HD800 at 300Ω is meant more for big production equipment which can put out that sort of power, for example a professional live music desk. This doesn't mean you...

The HD 650 utilizes a 9.8' detachable cable made from a highly conductive OFC copper with low handling noise and low structure-borne sound sensitivity. The headphones can be used with high-output mobile devices and excel with high-quality stationary hi-fi components such as SACD, DVD-A, and...
