## Questions & Answers

**Q: Will this work with a regular TV?**
A: As long as your TV has an AUX audio output jack, the Relay will work with it.

**Q: Will I get audio lag or lip-sync delays with my headphones?**
A: Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs.

**Q: How are the volume levels?**
A: You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.

**Q: How long does it take to fully charge the adapter?**
A: It only takes 1.5 hours to fully charge the adapter.

**Q: Can I connect my phone to the Relay via Bluetooth?**
A: No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth.

### ⭐⭐⭐⭐⭐ 簡単
*by ゆ***ん on July 14, 2025*

簡単！すぐ使えました。

### ⭐⭐⭐⭐⭐ 機内でコード気にせず普段のノイキャン、快適！
*by A***ー on September 25, 2025*

快適です。機内で映画見てても全く遅延気にならないですが、電子ピアノに変換プラグ経由で接続すると多少遅延を感じます。でも機内で映画見る時は気づかないレベルで、出張多い皆さん必需品です。

### ⭐⭐⭐⭐ 程よい大きさ
*by A***ー on May 28, 2025*

簡単に接続ができ、本体も程よい大きさです。機内放送とは若干の遅延がありハウリングしますが、普通に使う分には問題を感じなかった。
