Roku Premiere is a compact streaming media player that turns a non-smart TV into a Roku-powered home for popular apps. It supports HD, 4K, and HDR, includes a simple remote (with channel shortcuts), and can be controlled with the free Roku mobile app for voice search and private listening. The main caveat is that your TV still needs an internet connection and you may need to adjust to learning the Roku channel interface.
JLab Go Air Sport true wireless earbuds are built for active workouts, with earhooks for a more secure fit and IP55 sweat and dust resistance. They also offer long total battery life, multipoint Bluetooth 5.1, and three on-bud EQ modes (Signature, Balanced, Bass Boost), but buyer feedback suggests the sound and controls can take some setup and EQ tweaking to feel “right.”
The iFi iEMatch+ is a 3.5mm analog attenuator designed to reduce hiss and tighten up volume control when using IEMs or low-impedance earbuds with phone receivers, body packs, or other audio sources. It can help you hear more clearly at lower listening levels, but it is not a true “volume booster,” and some setups may trade hiss reduction for perceived changes in tuning or sound quality.
