Why does my DSA awarded headset/headphones/mic not work as well as I want or expect?

Entry level audio.

DSA-awarded audio equipment is usually very entry-level.

Microphones

Any "shotgun" Mic, for instance, may be labelled as such, but the Andrea SG-110M, and other similar Microphones is specifically only barely able to qualify as such.

We have tested multiple and they work as intended/in line with their specs.

If you try to record someone in a noisy/echo-filled auditorium with this mic, it will not work. If you try to record the entire auditorium or one person a few feet away, it will work.

In addition, examining the mic, we have found that in most DSA funded "shotgun" Mic's the polar patterns in the insert are for a unidirectional, cardioid mic. Not a shotgun.

When we test them in a relatively/under a few db environments, we find they work okay to pick up a single voice.

But are, by design not Omni directional. So once the lecturer/subject moves out of the capture field, which the further away they are can be very small, they will be muffled/hard to hear.

What this does mean is that a better Mic may be needed, but we can only supply what the assessor/student has agreed to and DSA approved.

Headsets/Headphones

With both Microphones and headsets/headphones as well, the noise cancelling features that are inbuilt will again be very entry-level/rudimentary, passive noise cancelling, not active. Expecting a £20-50 headset/headphone to have the same active cancelling features and abilities as a £300-10000 pair of headphones is not realistic.

It is worth taking a look at this article in order to get some good general tips for training these apps with the entry level equipment that DSA funds/awards.

Entry‑level headsets usually compromise on drivers, microphones, materials, and DSP, while mid‑tier and premium models add better components, stronger passive isolation, and advanced ANC. Using Andrea (entry‑level), Sony (mid/premium), and Bindy (budget/office‑grade) makes the differences very clear. No page content from your open tabs is relevant to this topic.

Below is a clean, structured breakdown you can use for procurement, training, or internal standards.

🎧 Tiers of Headsets: Entry‑Level vs Mid‑Tier vs Premium

🟦 1. Entry‑Level Headsets

Examples: Andrea / Bindy basic office headsets, Sony WH‑CH520 / WF‑C510 (budget line)

What defines this tier

  • Small, inexpensive drivers (28–32 mm)

  • Basic microphones with limited noise rejection

  • Minimal passive isolation

  • No ANC or very weak ANC

  • Plastic build, light but not durable

  • Limited frequency response → thin bass, harsh highs

  • No tuning DSP → inconsistent sound between units

Limitations

  • Struggles in noisy offices or lectures

  • Voice pickup is often nasal or compressed

  • Poor for long calls (comfort + mic fatigue)

  • Not suitable for audio/video editing

  • Short lifespan (hinges, pads, cables)

Best for

  • Basic use

  • Low‑noise environments

🟧 2. Mid‑Tier Headsets

Examples: Sony WH‑CH720N / WF‑C710N (mid‑range ANC), Bindy “Pro” office models, Andrea USB‑SA / NC‑250 USB bundles

What defines this tier

  • Better drivers (32–40 mm)

  • Directional or dual‑mic arrays

  • Improved passive isolation

  • Entry‑level ANC (Sony mid‑range is decent)

  • More comfortable materials

  • USB soundcards (Andrea) that improve mic clarity

  • More consistent tuning

Limitations

  • ANC is noticeably weaker than premium

  • Mic noise suppression still struggles with:

    • keyboard clatter

    • HVAC rumble

    • multiple talkers

  • Build quality is better but not “lifetime”

  • Sound quality is good, not reference‑grade

Best for

  • Hybrid work

  • Moderate‑noise offices

  • Users who need “good enough” ANC without premium pricing

🟩 3. Premium Headsets

Examples: Sony WH‑1000XM5 / XM6 (flagship ANC), Bindy enterprise ANC models, Andrea doesn’t really compete in this tier

What defines this tier

  • Large, high‑quality drivers (40 mm+)

  • Multi‑mic beamforming arrays

  • Class‑leading ANC (Sony XM series)

  • Strong passive isolation from premium pads

  • Advanced DSP for tuning, call enhancement, wind reduction

  • High‑end materials (memory foam, metal hinges)

  • Long battery life

  • Bluetooth multipoint, LDAC, transparency modes

Limitations

  • Higher cost

  • ANC can slightly colour audio (important for editing)

  • Heavier than entry‑level

Best for

  • Travel, commuting, open‑plan offices

  • Users who need excellent mic clarity

  • People who value comfort for long sessions

  • Anyone working in noisy environments

🧠 Key Takeaways for Procurement or Technical Standards

Entry‑Level

  • Cheap, replaceable, but poor isolation and mic quality

  • Good for low‑noise environments only

Mid‑Tier

  • Solid balance of cost and performance

  • Suitable for most hybrid workers

  • ANC is “fine” but not travel‑grade

Premium

  • Best ANC, comfort, and mic performance

  • Worth it for noisy offices or travel

  • Sony XM series is the benchmark

Active vs Passive noise cancelling.

Active and passive noise‑cancelling headsets solve the same problem in very different ways: passive blocks sound physically, while active uses microphones and electronics to cancel noise. Both approaches shine in different environments, and most modern premium headsets combine them for the best overall isolation.

🎧 What Passive Noise Cancelling (PNC) Is

Passive noise cancelling is simply physical sound isolation. Thick materials, tight seals, and over‑ear designs block external noise before it reaches your ears.

How it works

  • Uses earcup padding, clamping force, and materials to block sound.

  • No electronics, no microphones, no processing.

  • Works best on mid–high frequencies (voices, office noise).

Strengths

  • No battery required.

  • Zero latency, zero risk of audio artefacts.

  • Often better for studio monitoring because it doesn’t colour the sound.

  • Works consistently regardless of environment.

Limitations

  • Less effective against low‑frequency rumble (engines, HVAC, trains).

  • Comfort varies depending on seal and clamping force.

🎧 What Active Noise Cancelling (ANC) Is

Active noise cancelling uses microphones + digital signal processing to generate an “anti‑noise” signal that cancels incoming sound waves.

How it works

  • External mics capture ambient noise.

  • Internal processor creates an inverted sound wave.

  • The two waves cancel each other before reaching your ear.

Strengths

  • Extremely effective against low‑frequency, constant noise (planes, buses, tube rumble).

  • Adjustable modes (transparency, adaptive ANC).

  • Great for travel, commuting, and open‑plan offices.

Limitations

  • Requires battery power.

  • Can introduce slight pressure sensation or hiss.

  • Performance varies widely between brands and models.

  • Less effective for sudden, sharp sounds (clattering, speech).

🧭 Which Should You Choose?

Since you’re in London—where commuting noise and open‑plan offices are common—ANC tends to be the bigger quality‑of‑life upgrade. But if you’re doing audio/video editing, passive isolation is often preferable because it avoids DSP coloration.

A quick rule of thumb:

  • For travel / commuting: ANC

  • For studio accuracy: Passive

  • For all‑round everyday use: Hybrid ANC + good passive seal

  • For maximum silence: ANC + strong passive isolation (e.g., over‑ear ANC models)
