GTMEDIA X1 Android TV Box vs ADTH NextGen TV Box Gen 2

The ADTH NextGen TV Box Gen 2 is the better pick for most people who mainly want free over-the-air NextGen TV on an older screen. It adds HDR, Bluetooth 5.0, Wi-Fi 5 and 64GB of built-in storage with SD and USB expansion, and it handles ATSC 3.0 without needing an internet connection for DRM. The GTMEDIA X1 runs full Android TV 11 with the Google Play app ecosystem and records up to five shows at once, but its 2GB of RAM and 32-bit build limit it, and it has no HDR or Bluetooth listed. Owner feedback on the ADTH is mixed, with a low aggregate rating, so buy it for the tuner and treat the smart features as secondary.

  • Choose the GTMEDIA X1 if you want one box that streams Netflix and YouTube through Android TV and also records several over-the-air shows at once.
  • Choose the ADTH NextGen TV Box Gen 2 if your priority is clean ATSC 3.0 reception with HDR, Bluetooth and expandable storage on a TV you already own.

What reviewers say

ADTH NextGen TV Box Gen 2

Owner feedback is largely negative, with a 2-out-of-5 average. Buyers report setup trouble and unreliable tuning more often than they praise picture quality.

What people mention
  • ReliabilityCriticisedOwners report dropouts and failed channel scans that make the box hard to rely on.
  • SetupCriticisedBuyers say initial setup and firmware updates are confusing and slow.
  • PicturePraisedWhen a channel locks in, owners describe a sharp 4K HDR image.
  • AntennaMixedThe box needs a separate antenna, and results vary a lot with signal strength.

Questions and answers

Which is better for streaming apps?
The GTMEDIA X1. It runs Android TV 11 with app store access, so Netflix, YouTube and similar apps install directly. The ADTH is built around the tuner and its app options are limited.
Which handles NextGen TV better?
The ADTH. It adds HDR, Bluetooth 5.0 and unconnected DRM, so encrypted ATSC 3.0 channels play without a network. The GTMEDIA decodes ATSC 3.0 but lists no HDR.
Which records more?
The GTMEDIA records up to five shows at once from one frequency. The ADTH offers pause, rewind and replay plus DVR capability, with 64GB built in and SD or USB expansion for more room.
Is the ADTH worth stepping up to over the GTMEDIA?
If you mainly watch free over-the-air TV on an existing screen, yes: HDR, Bluetooth and expandable storage matter more there. If you want one box for streaming apps and heavy recording, the GTMEDIA does more.
Do both need an antenna?
Yes. Both are tuners, so over-the-air channels need an antenna connected. Neither includes one in the box.
Which is easier to live with long term?
The ADTH has more storage and expansion, which helps as recordings pile up. The GTMEDIA's 2GB of RAM and 32-bit build are the bigger constraint as apps grow heavier.
