Many owners love its clear dialogue, easy setup, and room-filling volume (up to 100W peak – view specs on Amazon). However, common feedback points to minor limitations: the included wall mount kit can feel basic and rigid, and the stock HDMI cable may occasionally contribute to sync or connectivity issues on non-TCL TVs.

This guide draws from “frequently bought together” patterns on Amazon to recommend practical accessories that address these real-user pain points. All picks are under $30 (prices as of December 10, 2025; check for current deals), highly rated, and focused on enhancing setup, reliability, and performance without breaking the bank.

Why These Accessories?

Amazon data shows the S45H often bundles with new TVs, and buyers frequently add specific accessories post-purchase. Reviews highlight:

  • Desire for a secure, non-bulky mounting solution to replace the basic included hardware
  • Need for guaranteed-reliable cables to maintain stable eARC connectivity and avoid audio drops
  • Optimization of power and placement for cleaner home theater management

These upgrades keep your total spend low while fixing the most-mentioned gripes.

Essential Accessories: The Fixes

1. Upgraded HDMI Cable (Certified eARC Reliability)

Using the HDMI eARC connection is crucial to unlock the S45H’s full potential, including Dolby Atmos processing. If you encounter the occasional sound drop or setup hiccup (especially when pairing with a non-TCL TV), the community often points to the cable as the weak link.

A certified Ultra High-Speed HDMI 2.1 cable provides more than enough bandwidth to ensure the eARC signal is flawlessly maintained, prioritizing stability over a basic, shorter cord.

  • Why you might need it: To ensure rock-solid stability for eARC/CEC control and eliminate the risk of intermittent sound drops or sync issues often associated with budget cables.
  • Amazon Pick: Highwings 8K 10K 4K HDMI Cable 48Gbps 6.6FT/2M – Around $7
  • Pros: Reliable 48Gbps bandwidth, certified eARC support, durable braided build.
  • Cons: Fixed length

2. Universal Soundbar Wall Mount Bracket: The Stock Kit Fix

Your S45H comes with a basic wall-mount kit, but many users find the hardware flimsy, leading to a loose or insecure fit. The lightweight nature of the S45H makes it ideal for no-stud solutions that are easy to install and provide better stability.

  • Why you might need it: To replace the rigid, poor-quality stock kit with a secure mount. This is also a fantastic preventative measure to keep the bar safe from accidental bumps, kids, or pets.
  • Amazon Pick: Mount-It No Stud Sound Bar Wall Mount (or similar) – Around $23
  • Pros: No-stud installation (uses small nails/pins, for drywall/renters), height/depth adjustable for perfect alignment, highly secure
  • Cons: Weight capacity is limited (though fine for the 4.5lb S45H).
  • Tip: Look for VESA-compatible mounts if your TV is on an articulating arm, or a No-Stud solution for the easiest installation.

3. Power Management & Surge Protection

The stock power cord is often short (around 5 feet/1.5m), which can limit placement options, especially when wall-mounting. Instead of a simple extension, upgrade to a surge protector with a flat plug.

  • Why you might need it: Solves short cord length issues, maximizes limited outlet space behind the TV, and protects your new electronics from power spikes
  • Amazon Pick: SUPERDANNY Flat Plug Surge Protector Power Strip 6ft Ultra Thin Extension Cord (or similar) – Around $17
  • Pros: Flat plug design, integrated surge protection, multiple outlets for other components (TV, streaming stick)
  • Cons: Bulkier than a simple extension cord

While HDMI eARC is the preferred connection, some older or budget TVs may not have a reliable HDMI ARC port, or you might need a secondary audio source. An optical cable provides a guaranteed, stable digital audio connection.

  • Why you might need it: Essential Plan B for TVs without eARC. It delivers lag-free digital audio and is praised by users with older setups who prioritize stability over higher-bandwidth features.
  • Amazon Pick: Warrky Optical Audio Cable, 6ft / 1.8m Optical Cable for Soundbar – Around $8
  • Pros: Crystal clear digital audio, works universally with almost any TV/soundbar combo, very affordable
  • Cons: Does not support high-resolution audio formats or CEC control (you’ll need the S45H remote for volume)

Bonus Accessory: Replacement Remote for TCL S45H Soundbar

The stock remote is functional, but many owners end up purchasing a backup because the small size makes it easy to lose, or they prefer a dedicated remote when CEC/T-Link control is unstable. This is a practical, quick-fix purchase for convenience.
