Listen for clear voices, balanced sound, useful volume, stereo presentation, and repeatable rattles or distortion. This is a practical listening check—not a calibrated measurement or a hardware diagnosis.
Set up a fair comparison
- Choose a quiet, familiar setting. Use the same room and listening distance for each phone. A familiar spoken passage and music excerpt make differences easier to notice than unfamiliar material.
- Make sure sound comes from the phone. Disconnect Bluetooth headphones or speakers, casting, USB audio, and other external routes. Confirm that media volume is on, then start at a low level.
- Keep the comparison consistent. Use the same audio, phone orientation, distance, and approximate perceived loudness on each device. A louder phone can seem clearer or fuller even when the difference is mainly volume.
Listen for the qualities that matter
Speech clarity
Play dialogue, a podcast, or another familiar spoken sample. Check whether words are easy to understand and voices sound natural. Raise the volume gradually and note any buzzing, crackling, or loss of clarity. If a voice becomes harsh or difficult to follow, compare the same moment on the other phone at a similar perceived level.
Music and tonal balance
Use a familiar music passage with voices and a range of instruments. Listen for whether any part of the sound seems unusually weak, boomy, thin, or distracting. If a tone sweep is available, it can help you notice repeatable rattles or changes across tones. It is only a listening aid: loudness changes during a sweep can be normal, and the sweep does not measure calibrated frequency response.
Useful volume and unwanted artifacts
Increase volume in small steps and note the highest level at which the sound remains acceptable to you. Listen for repeatable rattling, buzzing, crackling, or clipping. A single odd sound may come from the recording or surroundings; replay the same section at a moderate level and check another sample before treating it as a meaningful symptom.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Stereo and everyday positioning
Listen while holding the phone and while it rests in a position you would actually use. Notice whether your hand or the surface blocks an output and whether stereo presentation remains useful in your likely orientation. Phones can route audio differently, so an unexpected result from a left/right channel test alone does not prove that a speaker is broken.
Compare phones on the same checklist
| What to compare | What to listen for |
|---|---|
| Speech | Intelligibility and clarity on the same spoken passage. |
| Music | Tonal character on the same familiar excerpt, not just a synthetic sweep. |
| Volume | The useful level before artifacts become objectionable. |
| Artifacts | Repeatable buzz, rattle, crackle, or clipping at ordinary listening levels. |
| Orientation and stereo | Whether the presentation works in your likely grip and placement, and whether an opening is easily blocked. |
These checks help you decide which phone sounds better for your own use. They do not produce a comparable laboratory score: room acoustics, distance, orientation, playback level, and the recording can all influence what you hear.

What a listening check can—and cannot—establish
A browser-based audio test can play voice and tone material, but playback alone cannot provide calibrated loudness, frequency response, or a distortion percentage. Nor can it identify which component caused an artifact or certify that a phone is healthy. TestingPhone.com puts the limitation plainly: “A result describes what this test observed. It does not automatically diagnose the component inside the phone.”
Formal testing controls the stimulus, device position, room or fixture, and measurement equipment. RTINGS describes testing speakers at a defined distance from calibrated microphones, setting output to a target level with pink noise, and averaging repeated measurements for frequency-response results; its methodology also considers soundstage and dynamics. Those controls explain why a store-floor comparison is useful for personal preference and obvious repeatable faults, but cannot stand in for a calibrated result.

Published tests may report maximum output, frequency response, distortion, dynamic range, crosstalk, or channel behavior. The measurement method matters as much as the headline score. AnandTech’s 2013 smartphone-audio article is useful for understanding these categories, not for current model guidance. ITU-T Recommendation P.313 (June 2015) sets out electro-acoustic requirements and methods for mobile handsets, headsets, and speakerphone sets, including receiving and sending levels, frequency response, noise, sidetone, stability, echo path, and delay. It is standards context, not a consumer pass/fail checklist for media-speaker quality. ITU-T’s mobile handset methodology also illustrates that controlled speech and frequency-response results describe a defined reference setup, not every listener’s media playback experience.

If a formal sound-level result matters, an ordinary smartphone’s built-in microphone is not suitable for accurate measurement, according to ITU’s 2024 technical guidance. The guidance says a validated app paired with a high-quality external microphone may form a system meeting key class 2 sound-level-meter requirements; use a tested combination rather than assuming any phone or app is accurate.
