HIFIMAN SUNDARA review

Whether to use wired or wireless headphones is a hotly-debatable topic that often divides opinion. This time I am going to show you all the ins and outs of two wired devices Sennheiser HD 650 vs HIFIMAN SUNDARA. Both of the chosen headphone models are open-back and have an over-ear wearing style.

Features

The special thing about HIFIMAN SUNDARA is an incredibly wide frequency response which is 6 Hz - 75 kHz. Comparatively, the device Sennheiser HD 650 has a range of 10 Hz - 41 kHz. Another point worth noting is the distinction between their levels of impedance. The headphones produced by HIFIMAN have 37 Ohm, while the product of Sennheiser has 300 Ohm. The difference between the rates of sensitivity is less considerable since the first appliance has 94 dB and the second one — 103 dB.

Sound

Sennheiser HD 650 provides an incredibly natural, smooth, and absolutely non-fatiguing sound. The low mids are raised ever very slightly, giving the device some lush and warm feel. The mids are incredibly realistic and natural, and make instruments sound like they are supposed to sound.

HIFIMAN SUNDARA has an amazing wide soundstage, with more lateral extension than depth. Bass is very detailed and well-textured, with different layers being presented coherently and without any negative interactions between them.

Comfort and design

Let's start with comparing their audio cables. HIFIMAN SUNDARA comes with a detachable wire which is 150 cm long. The cable that you get with Sennheiser HD 650 is twice longer — 300 cm, and it is not detachable. None of the devices has a microphone, therefore making phone calls with these headphones might be uncomfortable. The weight of the model HD 650 is 260 g and HIFIMAN SUNDARA weighs 372 g. Although both devices are not very heavy, they do not fold which lowers their portability.

Pros

  • Incredibly comfortable to wear because of the special elliptical design adapted to the shape of the ears

  • Specially modulated connecting audio cable produced of highly conductive OFC copper, with pretty low handling noise, i.e. low structure-borne sound sensitivity

Cons

  • Pads compress and wear out faster than others
