Frequently Asked Questions
▶ What is the difference between TWS and normal Bluetooth headphones? TWS (True Wireless Stereo): two completely wireless in-ear headphones with no cable between the two pieces. Connection: one BT chip per earbud, one master connection to smartphone. Advantages: maximum freedom of movement. Disadvantage: smaller batteries (3–8h talk time), charging case needed. Normal BT headphones: cable between L/R or neckband, larger battery (8–40h). |
▶ Which Bluetooth audio codec is best for telephony? For telephony (bidirectional), codec is less decisive than for music playback (unidirectional). Telephony-relevant factors: latency (lower is better), microphone quality and HSP/HFP profile support. HSP/HFP (Hands-Free Profile) is the Bluetooth standard for telephony. For music playback: aptX HD and LDAC offer highest quality. |
▶ Why does my Bluetooth headset sound worse during calls than music? Bluetooth supports simultaneous audio playback (A2DP profile, up to 320 kBit/s) and telephony (HFP/HSP profile, only 64 kBit/s). During calls, the headset switches from A2DP to HFP (narrowband mode). Headsets with wideband speech (mSBC codec) in HFP profile improve voice quality to HD level – provided smartphone and headset both support wideband HFP. |
