The Technics EAH-AZ100 and Sennheiser MOMENTUM True Wireless 5 are both premium true wireless earbuds with strong reputations. They share a near-identical sound sub-score and similar battery claims, but they ask different things of your wallet and deliver different trade-offs in everyday use. This head-to-head works through the data from the HearWiki database to help you decide which one deserves your money.
Price and positioning
The Technics EAH-AZ100 are priced at $250, while the Sennheiser MOMENTUM True Wireless 5 cost $305. That is a $55 gap, which is not trivial at this end of the market. The Technics sit in the upper-mid premium tier, undercutting many rivals while still offering LDAC support and a 10 mm dynamic driver. The Sennheiser, by contrast, ask for a clear premium and lean on their brand heritage, a 7 mm dynamic driver and a full suite of aptX codecs including aptX Lossless.
Positioning matters here. The Technics are aimed at listeners who want high-resolution audio without paying the absolute top price. The Sennheiser are for those who value lossless Bluetooth transmission and are willing to pay extra for it. Neither is a budget option, but the Technics are the more accessible of the two.
The scores, side by side
The headline HearWiki scores are 86/100 for the Technics EAH-AZ100 and 83/100 for the Sennheiser MOMENTUM True Wireless 5. That is a three-point gap, which is meaningful but not dramatic. The Technics lead on ANC (8.6 vs 8.3), battery (8.7 vs 8.2) and value (8.1 vs 7.5). The Sennheiser lead on calls (8.7 vs 7.8). Sound is a dead heat at 9.2 for both.
These sub-scores are category summaries from published reviews and recorded specifications; they are not a weighted average of the headline score. The headline score reflects buyability across review consensus, price and availability. So the Technics' higher headline score comes largely from their lower price and stronger battery performance, not from a sound advantage.
Sound
Both earbuds score 9.2 for sound, which is exceptional. The Technics use a 10 mm dynamic driver, the Sennheiser a 7 mm dynamic driver. Driver size alone does not determine quality, and the scores reflect that these two are very close in published listening impressions. The Technics support SBC, AAC, LC3 and LDAC, which is great for Android users with LDAC-capable phones. The Sennheiser support SBC, AAC, aptX, aptX Adaptive and aptX Lossless, which is better for Android users who want lossless quality and for devices that support aptX.
If you are on an iPhone, both will use AAC, so the codec difference largely evaporates. On Android, the choice comes down to whether you prefer LDAC (Technics) or aptX Lossless (Sennheiser). Neither is objectively better; it depends on your phone and your ears. The published reviews suggest both deliver rich, detailed sound with strong bass and clear highs, so you are unlikely to be disappointed by either.
Noise cancelling and battery
Both have adaptive ANC. The Technics score 8.6 for ANC, the Sennheiser 8.3. That is a small but consistent lead for the Technics in published comparisons. The Sennheiser's ANC is described as effective but not class-leading, while the Technics are often praised for their ability to adapt to changing environments.
Battery life is where the gap widens. The Technics offer 12 hours on a single charge, or 10 with ANC enabled, and 28 hours total with the case. The Sennheiser also claim 12 hours without ANC, but drop to 6 hours with ANC on, and 40 hours with the case. So the Sennheiser case lasts longer overall, but the earbuds themselves die much faster when you use ANC. If you commute for an hour each way and leave ANC on, the Technics will last nearly two full days, while the Sennheiser will need a case recharge after about three days. The Technics' 10-hour ANC figure is a clear practical advantage.
Both support wireless charging. The Technics are rated IPX4 and the Sennheiser IP54, so both are fine for workouts and light rain, and the Sennheiser add dust protection.
Calls and everyday use
The Sennheiser lead on call quality with a sub-score of 8.7, versus 7.8 for the Technics. That is a notable gap. Published reviews suggest the Sennheiser handle wind noise and background chatter better, which matters if you take calls on the street or in open offices. The Technics are not bad, but they are not at the same level for voice pickup.
In everyday use, the Technics offer multipoint pairing for up to three devices, while the Sennheiser support multipoint as well, though the exact number of simultaneous connections is not recorded in the database. The Technics use Bluetooth 5.3, the Sennheiser Bluetooth 6.0. Bluetooth 6.0 is newer and brings better efficiency and range in theory, but in practice the difference is unlikely to be noticeable for most listeners.
Touch controls on both are described as requiring a learning curve. Neither is a clear winner there. The Technics include no ear tips in the box, which is a minor inconvenience if you need a different size. The Sennheiser's fit is generally praised, but that is subjective.
Which one should you buy?
If you want the best battery life with ANC on, a lower price and LDAC support, buy the Technics EAH-AZ100. They are the better value for most people, especially commuters who leave ANC enabled all day.
If you prioritise call quality above all else, or you have an Android phone that supports aptX Lossless and you want lossless Bluetooth audio, buy the Sennheiser MOMENTUM True Wireless 5. They cost more and their ANC battery life is poor, but their voice pickup is clearly better.
