As far as true wireless earbuds go , when it descend to call calibre they ’re often not corking . If you want to make a call , you ’re stuck with wretched pickaxe - up of your articulation or the noise - cancellation battle to make you audible to the someone on the other end .

It ’s a trouble no sound manufacturer seems to have fully clear . But that could change with the Technics AZ100 .

It ’s the latest flagship true wireless from the honored audio mark , who is celebrating its 60thanniversary in 2025 , and it has come out swing with a performance that demand on the likes ofBose , Sony , and evenBowers & Wilkinsin the truthful wireless department .

I was invited to go to Kyoto to see ( and hear ) the headphones in December 2024 , and compare to theAZ80model of before , they are an improvement across the board . But it ’s call tone I ’m soar in on , since it ’s been such a frustrating surface area oftrue wireless earphonescompared to full - sized over - spike manikin .

Recent Sony truthful tuner have n’t been peachy for call quality . With Sennheiser it ’s been inert , while for Bose it ’s been its weakest domain . The summation of auto learning algorithms in an update in 2024 did n’t seem to operate very well .

For each true wireless I test , I seek to do a call timbre test by bugging a booster and walking around the Southwark / Bankside area in London . Some true wireless have fared well , often the mid - range framework surprisingly , while premium earbuds tend to be iffy . put the Technics AZ100 through its paces , and on a day when the weather was n’t not bad , I could n’t blame its carrying into action .

My friend thought I was call him on a pair of over - spike , which have a higher degree of operation than a true radiocommunication . He was impressed by little noise he could hear ( aside from a cacophony ambulance going past ) and how well the AZ100 focused on my vocalisation . And it ’s all down to Technics ’ Voice Focus AI lineament .

This is one of the best carrying out of AI ( or simple machine learning ) I ’ve hail across in a true wireless , an AI feature where it ’s clear tohearthe impact it has . Switch it on in Technics Audio Connect app , and the AI noise reduction flake strips off the noise around you leaving only your voice . exchange it off and the difference could n’t be more stark – the person on the end of the line of reasoning sound off I sounded like I was in a rainy downpour .

This is a leap forwards because the Technics AZ100 could be one of the first true wireless that works well in bothquietandnoisyenvironments ; a balance other earbuds seldom get right . If you desire to use these earphones for calls out of doors , you may . If you want to use them for workplace then they ’re probably a more commodious choice than full - sized over - ears ( especially with the AZ100 ’s multi - point Bluetooth support ) . And you no longer have to profusely apologise for how bad your call quality is .

So while the improvements in sound , ease , and noise - cancellation are all welcomed with the Technics AZ100 , it ’s the find in call quality that will be these headphones now not - so - secluded weapon . When it do to call calibre , I cerebrate these are the true wireless to flap .
