Here’s what VOYX BD-104 earphones might include or be like, based on similar models:
Feature Likely Value / Behavior
Connector 3.5 mm audio jack (standard, compatible with most phones, laptops, etc.)
Drivers Possibly dynamic drivers, size might be in the 10-12 mm range (common for earbuds at mid-budget).
Sound / Frequency Response Probably about 20 Hz to 20,000 Hz — standard range for music listening. Lower end for bass; upper end for treble.
Sensitivity / Loudness Somewhere around 90-100 dB/mW is typical in this class — loud enough for most listening, but not high-end audiophile level.
Cable Standard length (1.2-1.5 m maybe), probably a round cable (unless VOYX has flat/tangle resistant design). Cable will have plastic insulation; might include inline microphone + remote.
Microphone Likely included, since most VOYX wired earphones have a built-in mic on the cable for calls.
Controls Probably a single button or few buttons (play/pause, answer/reject). Might not have advanced controls like volume up/down if budget model.
Build / Comfort Light plastic housings, silicone ear tips (if in-ear style) of different sizes for comfort. Decent fit but not premium materials.
Noise Isolation Some passive isolation (from design and ear tips if in-ear), but not active noise cancellation.
Impedance Likely something like 32 ohms or similar — to work well with phones without needing high voltage.
