This article covers AudioQuest Forest 48 1.0m 8K-10K 48Gbps HDMIケーブル (3.3フィート).

Overview

The AudioQuest Forest 48 1.0m is a premium HDMI 2.1 cable designed for 8K and 10K Ultra HD video transmission with a blistering 48Gbps of bandwidth. It achieves this through four balanced audio/video pairs, each operating at 12Gbps, ensuring a powerful and immersive experience. The conductors are made from Long-Grain Copper (LGC) with a thicker layer of silver plating to improve noise dissipation, placing superior metal on the outside where it brings the most benefit.
This cable is 1.0 meter (3.3 feet) long, making it ideal for short runs between a TV and soundbar, A/V receiver, or gaming console. It features direction-controlled conductors: the arrows on the plugs indicate the correct orientation toward the TV (or source) for optimal RF noise reduction. If you demand top-tier video and audio fidelity without breaking the bank, the Forest 48 is a compelling choice.

Connectivity & Compatibility

The Forest 48 fully supports the HDMI 2.1 specification, including 48Gbps bandwidth, Dynamic HDR, and enhanced Audio Return Channel (eARC). It can handle 8K@60Hz and 4K@120Hz without compression, making it compatible with the latest gaming consoles (PS5, Xbox Series X) and high-end GPUs (NVIDIA GeForce RTX 30/40 series) that feature HDMI 2.1 outputs.
All 19 conductors are direction-controlled, and the eARC conductor pair is internally oriented opposite to the video pairs to ensure premium audio performance. The standard HDMI Type-A connectors are male on both ends, and the cable is designed to be plug-and-play—just follow the arrow direction. The cable is also backward compatible with earlier HDMI versions, though you will lose the benefits of 48Gbps bandwidth.

Product Info

The AudioQuest Forest 48 sits in the mid-to-upper-mid range of AudioQuest's HDMI cable lineup. It is not as expensive as the flagship Pearl 48 or Diamond 48, but it carries a clear premium over generic cables. Released around late 2020, it was one of the early 48Gbps-certified cables on the market and remains a solid choice. The manufacturer offers a limited lifetime warranty (requires proof of purchase). No accessories are included beyond the cable itself, which comes in a simple yet elegant branded sleeve.
In terms of market positioning, the Forest 48 strikes a balance between advanced technology (LGC silver-plated conductors, direction-controlled shielding) and reasonable pricing for the high-end segment. It is targeted at enthusiasts who want verified 48Gbps performance and better noise rejection than standard cables, but do not need the most exotic materials used in AudioQuest's top-tier models.

Best Use Cases

  • Home Theater Enthusiasts: If you have a 4K/8K projector or large OLED TV connected to an A/V receiver, the Forest 48's robust shielding and direction control reduce the risk of signal interference from other cables or Wi-Fi devices. The eARC support ensures lossless Dolby Atmos playback. However, if your setup is simple (e.g., game console directly to TV), a cheaper cable may suffice.
  • PC Gamers Targeting High Refresh Rates: With an RTX 4090 or similar HDMI 2.1 GPU, you can push 4K@120Hz or 8K@60Hz with VRR. The Forest 48's certified bandwidth ensures no chroma subsampling or dropped frames. It also works with DSC, which some monitors use to achieve higher refresh rates at 8K. For 1080p gaming, this cable is overkill.
  • Audiophiles Using eARC: If you route TV audio over eARC to a soundbar or receiver, the Forest 48's dedicated direction-controlled eARC pair minimizes jitter and noise in the audio signal. This is especially noticeable with high-resolution multichannel content. Users with basic stereo setups won't benefit.

Things to Consider

The Forest 48 is a premium cable with a price to match. At around ￥25,000 from Japanese retailers, it is several times more expensive than a standard HDMI 2.1 cable. If you do not have HDMI 2.1 source and display equipment, you will not see any difference in picture or sound. The cable is relatively stiff due to its thick gauge and shielding, so routing it in tight spaces may require some care. Also, keep the direction label in mind when connecting.

FAQ

Q: Do I need this cable for my PlayStation 5?
A: The PS5 supports HDMI 2.1 (up to 48Gbps), so the Forest 48 will allow it to output 4K@120Hz with HDR. However, many cheaper certified 48Gbps cables also work. You pay extra for AudioQuest's build quality and noise rejection, which may be noticeable in high-end home theater setups.
Q: Is this cable compatible with my older TV that only has HDMI 2.0?
A: Yes, it is backward compatible. You will get 4K@60Hz as before, but the extra bandwidth and shielding are unused. For an older TV, a standard High-Speed HDMI cable is sufficient.
Q: How long does this cable last?
A: With a limited lifetime warranty and durable connectors, the Forest 48 should last through many years of use. The silver-plated conducto
