This article covers AudioQuest Forest 48 2.1 HDMIケーブル.

Overview

The AudioQuest Forest 48 2.1 HDMI Cable (1.5m) is a high-performance cable designed to handle the full bandwidth of HDMI 2.1, supporting up to 48Gbps data transfer. It enables 8K/60Hz and 4K/120Hz video, along with HDR10+ and Dolby Vision, while also supporting eARC for high-quality audio return. With its high-purity copper conductors and low-loss dielectric construction, the Forest 48 strikes a balance between affordability and signal integrity, making it a strong choice for home theater enthusiasts, gamers, and professional AV integrators.

Connectivity & Compatibility

This cable is fully compliant with the HDMI 2.1 specification and backward compatible with earlier HDMI versions. It works with any device featuring an HDMI port: 4K/8K TVs, projectors, game consoles, PC graphics cards, and AV receivers. The 48Gbps bandwidth ensures support for the highest resolutions and refresh rates, including 10K professional video. eARC functionality is fully supported, allowing lossless audio (Dolby TrueHD, DTS-HD Master Audio) to be sent from the TV to an AVR or soundbar without additional cables. The 1.5m length is ideal for most setups, keeping the cable run short to minimize signal degradation.

Product Info

The AudioQuest Forest 48 2.1 HDMI Cable was introduced in late 2020. It sits at the entry-to-mid tier in AudioQuest's HDMI lineup, offering premium build quality at a more accessible price point than the higher-end Pearl or Cinnamon series. In Japan, it is widely available through online retailers and select electronics retailers, with a typical street price around ¥23,000. The cable comes with a limited lifetime warranty when purchased from an authorized dealer, though the warranty terms may vary by region. No additional accessories are included beyond the cable itself.

Best Use Cases

  • Home theater owners with 8K displays: If you've already invested in an 8K TV or projector, this cable ensures you're getting the full 8K/60Hz experience with HDR. The 48Gbps bandwidth also future-proofs your setup for upcoming 10K sources.
  • Gamers demanding high refresh rates: With HDMI 2.1 consoles (PS5, Xbox Series X) or PCs using RTX 30/40 series GPUs, the Forest 48 enables 4K/120Hz with VRR and ALLM. The 1.5m length is perfect for connecting a console near the TV or a PC to a monitor.
  • Professional AV integrators: For installations requiring reliable, certified HDMI 2.1 cables at a reasonable cost, the Forest 48 offers consistent signal integrity. Its flexibility and low-loss design make it suitable for in-wall or rack setups.
  • Audiophiles using eARC: If your AVR or soundbar supports eARC, this cable unlocks the full potential of lossless multichannel audio from streaming apps or Blu-ray players, without needing a separate audio cable.
    That said, if you're only using older 1080p or 4K/60Hz devices without HDR, a cheaper HDMI 2.0 cable will suffice. The Forest 48's higher cost is justified only when you need the full HDMI 2.1 feature set.
