Switch your Sony headphones on before you plug them in — you’ll get noticeably fuller, more reliable wired sound. Also pick LDAC for top fidelity or LC3 (LE Audio) for lower power and steadier Bluetooth, and use Sony’s Sound Connect app to change codecs and bitrates.

Turn the headset on before you wire it One easy improvement is a small habit change: switch the headphones on before you plug in a 3.5mm cable. When the headphones are off, their digital signal processing is inactive and wired output can sound thin and distant. Power the headphones first when you’re listening via a wired connection; only leave them off if the battery is nearly empty and you must get any sound at all. Pick the right codec for wireless listening Bluetooth audio quality depends on the codec your phone and headset negotiate. Common options are SBC and AAC, while many Android phones also support LDAC and the newer LC3 used by LE Audio. LDAC can deliver the highest fidelity on a steady link because it sends more data, but it uses more power and needs a strong radio environment. LC3 (LE Audio) usually uses less power and often gives higher effective bitrates than SBC or AAC on Android, so it can offer steadier links and better battery life in many situations. Sony’s app exposes an "LE Audio Priority" option to prefer LC3 on compatible devices. Use Sony’s app to tune performance Sony's Sound Connect app makes switching codecs and bitrates straightforward. There’s a toggle to prioritise sound quality on Android and bitrate choices for LDAC so you can opt for higher rates when fidelity matters or lower rates to save battery. The same headphones will behave quite differently depending on codec and bitrate: higher LDAC rates reveal more texture and dynamics, while lower LDAC rates or SBC can sound more compressed. Practical trade-offs for everyday use Not everyone will use LDAC all the time — it’s best in stable radio environments (home, office, near your phone) and when you prioritise top detail. In busy, congested areas (commutes, city streets) LDAC can drop packets and stutter; LC3 or AAC tends to be steadier there. For long listening sessions where battery life matters more than absolute detail, LC3 is often the better choice. Why small changes make a big difference The improvements come from two factors: active digital processing in the headphones (which restores fullness when enabled) and the codec/bitrate negotiated over Bluetooth (which affects how much audio data reaches the headset). Together, powering the unit before wired use and choosing the right codec via Sony’s app usually delivers the biggest audible gains without upgrading hardware.
