Rated 5 van de 5 door uit Verslag na ruim 5 jaar gebruik. Ik gebruik deze headset thuis, om (loop) geluiden van de bovenburen buiten te sluiten. Ik ben zeer gevoelig voor externe geluiden (syndroom van Asperger) en draag deze headset daarom 24 uur per dag (yup, ook 's nachts). Ik geloof dat ik de earcussion gemiddeld eens per jaar heb vervangen; het binnenwerk wordt nu onderhand wel erg vuil maar heb het onlangs gewoon zelf eens schoongemaakt ('t zijn vooral haren en stof die er in komen). Het schuimrubber in het binnenwerk lijkt onderhand iets te beginnen te verkruimelen. Omdat ik deze headset non-stop gebruik zijn batterijen een no-go. Ik heb daarom een headset met LEMO plug aangeschaft zodat ik de headset ook via een externe kabel kon voeden (zelf een voedings kastje gebouwd; de plug waar de headset in moet is los te koop). Hier blijkt echter een probleem te zijn: de aarding van het audio signaal en ground van de voeding gebruiken dezelfde kabel in het snoer! Dat veroorzaakt hoorbare geluiden bij veranderende belasting van de headset; met name de blue-tooth, maar ook de knipperende LED die aangeeft dat de headset aan staat geeft een zacht maar hoorbare hum dat vooral irritant is omdat het elke seconde aan en uit gaat. Ik kon daarom blue-tooth niet gebruiken. De power LED is niet te horen wanneer je ook muziek op hebt; maar omdat ik de headset ook 's nachts ben gaan gebruiken vond ik de volgende oplossing: Ik heb de 6-polige LEMO plug vervangen door een 7-polige plug (zie foto's) hetgeen mogelijk bleek omdat de headset kabel weldegelijk 7-polig is! In de blue-tooth unit zijn echter de twee draden voor massa aan elkaar gesoldeerd (een lagere impedantie voor de ground wire verlicht dit euvel ook, uiteraard), dus ook die moeten worden gescheiden. Ik neem aan dat Bose geen keus had omdat er geen 7-polige aviation plug bestaat. Desalnietemin leek me dit interressante informatie voor de wat technischer koper. Ik gebruik nu zelfs een 10 meter lang verlangsnoer en heb geen last meer van de knipperende LED of zelfs de blue-tooth. Verder spreekt het voor zich dat ik deze headset de maximale beoordeling geef. Comfort is 100% (dat het uberhaupt mogelijk is de headset zo veel op te hebben!). Geluids kwaliteit is voldoende voor mij (je hoort inderdaad een zacht ruis, maar dat hebben alle noise-cancelling headsets); mijn eigen tinitus is momenteel harder dan het geluid dat de headset maakt ;). De duurzaamheid van de headset lijkt me ook wel bewezen; ik heb slechts eenmaal zo'n riemklip gebroken omdat ik plots opstond en het ding ergens aanvast zat dat niet mijn riem was.

Accessories FAQs


What makes the A20® Aviation Headset different from other products on the market?

The A20® headset offers an unmatched combination of clear audio, noise reduction and comfort, combined with the advanced features that pilots value, such as Bluetooth® audio streaming, customisable audio prioritisation, auto-on (selected models) and smart shutoff. In addition, Bose® has significant experience engineering mission-critical communication headsets used in a variety of applications, including unique headsets for military air and ground operations, the NFL and consumers worldwide. Bose® was the first company to introduce commercially available, active noise reduction headsets to the market and has over 25 years of experience providing headsets for critical communications globally, with 16 service centres worldwide.

Can I listen to music or other audio wirelessly via Bluetooth®?

Yes, the Bluetooth® music experience is the best way to listen to music wirelessly and provides Bose® quality sound. You can also stream warnings and alerts from your favourite apps. In addition, the A20® headset also has other Bluetooth® profiles, including hands-free calling and multi-point, which allows you to connect to more than one wireless device simultaneously.

Do I need to do anything to optimise the performance of my headset?

No. The headset constantly adjusts to the noise environment and automatically optimises the performance it delivers.

Why is TSO important?

A Technical Standard Order (TSO) is a minimum performance standard for specified materials, parts and appliances used on civil aircraft. When a company is authorised to manufacture a material, part or appliances to a TSO standard, this is referred to as TSO authorisation. When a company receives a TSO authorisation, it is assured that the product meets these minimums in both design and production. Bose® Corporation meets all and exceeds many TSO requirements.

Can I comfortably wear eyeglasses and hats with the A20® headset without impacting the headset's performance?

Yes. The earcups' supple leather-covered foam cushions are designed to provide an effective acoustic seal even over glasses. You should be able to wear your glasses comfortably without significantly diminishing the headset's noise reduction benefits. There is no need to calibrate or recalibrate the headset to maintain optimal performance. The headset adjusts automatically.

Does the A20® headset have auto-on or auto-off capability?

Yes, the aircraft powered version of the A20® headset has both auto-on and auto-off capability, so when the avionics have been turned on, the headset will turn on automatically once aircraft power is detected. Battery-powered versions of the headset have auto-off, but require that you press the power button to turn on the headset.

Can I convert my 6-pin plug headset?

Adapters are available from Bose® to convert a 6-pin connector to either a dual G/A plug or a U174 for additional connection flexibility.

Can I switch the boom microphone from the left-hand side to the right-hand side?

Yes. The boom mic can easily be swapped from the left- to right-hand side (or vice versa) by unscrewing two screws and repositioning the mic onto the desired earcup.

Are original Aviation Headset X® accessories compatible with the Bose® A20® headset?

Not really. While these cushions and parts may be forced onto the A20® Aviation Headset, they have not been designed or implemented for this product.
