Pulsar eS HE 70 specifications and in-depth review

Pulsar eS HE 70

Manufacturer: Pulsar

The Pulsar eS HE 70 is a 75% compact mechanical gaming keyboard built around a fully aluminum construction, giving it a solid and consistent feel in daily use. It connects via USB with a detachable cable, supports adjustable feet for ergonomic positioning, and includes per-key RGB backlighting across a standard ANSI layout. The keyboard ships without a wrist rest and is not designed specifically for Mac systems, though it uses a standard keycap layout that accommodates most replacement sets.

At the core of the eS HE 70 are Raesha Magnetic Switch hall effect linear switches, with an actuation force of 55 g and an adjustable actuation range spanning 0.5 mm to 4 mm, enabling rapid trigger functionality and analog input support. The switches are hot-swappable and sit on an aluminum plate. The board operates at up to 8000 Hz polling rate and supports full N-key rollover. Keycaps are PBT double-shot in an OEM profile, and a rotary dial is included for on-the-fly input adjustments. The keyboard measures 311 × 124 × 45 mm, weighs 967 g, and is backed by a 3-year warranty.

Pros
  • Actuation distance is adjustable from 0.5 mm to 4 mm, giving users precise control over how sensitive each keypress feels
  • Rapid trigger and analog input support are both present, enabling more responsive keystroke registration
  • Hall effect switches are hot-swappable, allowing switch replacement without soldering
  • Both the case and plate are made from aluminum, providing a rigid and stable typing surface
  • An 8000 Hz polling rate ensures very frequent input reporting to the system
  • The detachable cable makes transport and cable replacement straightforward
Cons
  • No wrist rest is included, which may be inconvenient for extended typing sessions
  • Media controls are only accessible through the Fn key rather than dedicated keys
  • Dual actuation is not supported, limiting certain advanced input configurations
  • USB passthrough is absent, reducing desk connectivity options
  • The keyboard does not have an onboard display for settings feedback
  • At 967 g, the weight is relatively high for a 75% form factor keyboard
Who is this for?

This keyboard is well-suited to users who want precise input control, particularly those who benefit from rapid trigger and adjustable actuation in fast-paced gaming scenarios. The hot-swappable hall effect switches and 8000 Hz polling rate make it a solid fit for users who actively tune their hardware setup. Its aluminum construction and compact 75% layout also appeal to those who prioritize a rigid, space-efficient desk setup without sacrificing a standard key arrangement.

Who is this NOT for?

Users who rely on dedicated media keys for quick audio or playback control may find the Fn-layer-only approach inconvenient during daily productivity work. The absence of a wrist rest and the relatively high weight of 967 g could be a drawback for those who need a lightweight or ergonomically complete solution out of the box. Additionally, users looking for Mac-compatible layouts or USB passthrough for desk peripheral management will find this keyboard lacking in those respects.
